 Hello boys and girls welcome to another episode of the Subaru Ice Racing project. A little heads up on this one it's a it's longer than usual it's because there's a lot of talking involved in this one could be boring but I decided to include everything that we recorded and that includes pretty much getting ready for a swap for a different transmission and rear diff because as some of you may know we do have issues with the center diff which is garbage at this point but we get to the bottom of it how and why it it broke some of you may be doing a swap from an older Subaru this is going to be a 98 to 99 could even be 2000 not sure but definitely 98 99 legacy GT transmission and diff we're going to fit that in into the 06 impresa 2.5 so stay tuned for that so as always like subscribe we do need subscribers as you can see sitting on what 600 something as soon as we're done with this car we're going ice racing then quite possibly rally cross and then come spring summer time it's going to get autocrossed on pavement and then maybe we're going to do all kinds of modifications weight reductions and whatnot remember everything is as cheap as possible and we might even take it to a track day we'll see it's going to be slow but still so thanks in advance and enjoy the video all right guys after pondering on what this is these pieces here what it used to be these we know that was that big c-clip that held on the actual diff plates in right here would be the very last thing that we that you would install to hold this in place but then what is this at first we thought this is pieces of gears because we had you know missing teeth like this chipped off teeth on both gears in this last case so on that basis we took apart the transmission now we went through all the gears on this part of the transmission and these are good pinion ring gear everything looks good it actually not even that dirty just apart from oil being having a few tiny tiny metal particles but no chunks at all in this part of the case so nothing got stuck in any oil passages nothing this is all clean you can here see no chips every single tooth is intact no overheating signs or under races from bearings i'm going to show you how these gears work here are your gear selectors okay there's three and basically as you switch gears with this guy here if this goes in out and then turns well not you know twists slightly as you move the gear lever left or right to select either reverse fifth one or or second and that's this guy here right right can you see so this guy she won't be able to move this probably okay a little bit so this is side to side right there are springs inside there and then this will move up and down like that so that's your main shift gear selector so this part this guy would sit right in here right there so right now all of these are lined up one two three and i'm going to turn so this shaft is the main shaft coming out of the engine let's say right that's your power here so right now although this turns this is still neutral because what i gotta do just hold it in place see i can still spin the this shaft so ever wonder why wheels if the car is lifted and even the if the car is in neutral on manuals the car is neutral but the wheels still spin this is why because this still spins as you can see freely although i can still you know hold it in place if i let go it will spin anyways so let's say i'm going to start with reverse i'm going to move this lever this way is that reverse i think that's reverse let's try move this forward this might be fifth i'm not sure actually so now i gotta take it back to neutral let's push this one for example there see how slow much slower this yeah that's what i was fifth so this is if that's reverse fifth fourth third first second so this is second so you gotta spin this much quicker to make this move so if i move this back come on now it's not easy i'm still not in gear this could be second yeah that must have been second and then you move this centered lever back and forth this just means that it's not in gear all the way it also helps to have the case on so although this is not loose anyway well when we were driving the car man my fingers all the gears were going in with no issues at all i mean you know it's on the previous episodes that's more or less how manual transmissions work basically these guys here are synchronizers also the way they work is that you have that these extra plates inside here so this is this is it right here one more there so you got two on each side here there's one on that side same thing on here and then one here if i were to choose what gear is that i can't spin this maybe i can see watch this shaft here see it spins slower now i'm just going to spin it back and forth it's just easier it started spinning much faster now it's in slower faster as soon as you start even pushing on this this this will kind of pre-select well not pre-select but see now wants to go in gear well i don't want it to it will push on the gear next to it and kind of grab match your speed will start spinning the shaft or the gear you're about to select before the gear even is in that's why you don't need to kind of match your you know rev up the engine to put a gear in like in semi trucks for example semi trucks will not have these so that's it that's basically more or less how this works to take this this shaft i can just lift off lift up this will come off and to remove like these forks here there are pins inside you got to knock them out and these selectors will come out then you can remove this guy all these and then it's just a bunch of pressing out and in bearings gears and whatever if you were to do a full service on it you would be replacing all these different bearings all right so now i'm going to show you what went on what we suspect is the issue here so this we know that's the broken c-clip or c-clip whatever however you want to call that so the differential this is what came out there this is sealed inside these plates that's your actual diff that's your lsd there's a bunch of them as you can see they're all glued together with this silicon smelly stuff then this will apart go apart you got more i just didn't put all these back together it's just time consuming there's no point this is i mean this should be you know more oily looking color not black so this is burnt this heated up oil turned black and these spider gears come on now this one turns freely but these teeth on it are slightly actually chipped off so not slightly but you know this is this is garbage this one although it's got less damage on the teeth it will not turn so something happened to this guy and here there's damage here you got it's got some sharp edges here and there so so the mystery what is this and there's a you know bunch of little pieces so this was a kind of a clip i guess we i can't you know i don't take these all apart on a daily basis so don't quote me on names or whatever that this but this used to be some kind of a clip i at first i thought it was a washer but this used to be a clip where it would go right here that's where it used to be and it used to be on the outside imagine this being in here like that and you got space right here right okay so now this actually can spin that that clip was right in between the spider gear and kind of at the body of the diff right on both sides so what we think happened was the rear wheels most likely were being dragged or were understood on the road the front was lifted after the accident the tow truck was like whatever you know let's work for me this is junk anyways he saw the the car the if you're watching this video first time there is a picture in the episode one how this car was actually damaged it was front passenger side so going back to the tow truck tow truck guy he said effort so instead of lifting the whole car he just dragged it basically that's what destroyed this diff this just pretty much exploded forced out the clip and all these all these were in this casing right here you can see still more parts right over here so none of this actually got through to the transmission which is good news a diff like this is about 600 at the dealer and a bunch of bearings whatever would wouldn't make sense to not change these bearings so you could just get a diff get these two shafts with the broken teeth right there's two of them pressing new bearings just the end of the you know this the second part the end of the transmission put all that together and it would be good you know but look actually went to get a transmission he's had for some time now and it's from a 98 or a 99 legacy and the rear diff is also different and because the gears are different in the transmission we would need to change the rear diff as well and he's got that also so he's gonna bring that i'm gonna put this one back together i'm not i'm not gonna be torquing anything or sealing up or whatever just slap it all back together so it doesn't know these bigger parts don't get lost all the bolts it's all gonna go back i'm gonna put it aside and inspect the new old transmission all right guys so this one is back together and we do have a replacement from a 98 older model we got a diff yeah i put it inside yeah we might actually keep that transmission for a rear wheel drive we're gonna we can weld the anyways so these gotta come out so we can test fit the CV axles so yeah without see the original axles they there's a pinhole here that's how the axles attach through a pinhole the oil was fine on this we did drain the oil looks good this mount cuts to go these look identical the same same colors even cool same colors all right so these will stay i don't know what that wire is for maybe it was uh oh i know what that might have been because this is the same as a sti i think 95 sti uh case okay and sti has a dccd five speed oh yeah maybe okay but i don't know i'm just making that we're just making things up all right uh the the slave cylinder well slightly different but as long as the mounting is the same we can reuse that one we're gonna check on that later oh yeah this is gear gear ratio 411 that's why we need to change the rear diff speed sensor this guy here different wiring okay we're gonna undo this one we've got three wires on the you know this transmission two wires on this one so i don't know so next step for us is to take these out and uh test fit the CV axles it should be fine i mean Subaru doesn't change things often it's like you know Honda Civics and Ford focuses there you go transmission will go right slave cylinder slag will work that's what we need oh yeah actually we need we need to still check all the attachments for the the fork the shifter shifting fork thingy throughout bearing see if that's gonna fit lose we need a sleeve oh it's weird this yeah this is worn but maybe doesn't come out like that too far okay so this shaft is worn right over here and i think there is a fix you put a yeah there is different different bearing and sleeve yeah like a sleeve so that may be a problem okay so that's number two that we need to figure out next day boys next day this is the legacy transmission it seems like it's it's gonna still gotta take these out but we're gonna try to take the front diff we're gonna take this apart is what i'm saying because we only have gear one and two this will not twist this way it will this way but one that way it's stuck so we're missing one and two that's where we're gonna take this apart and see what's going on could be an easy fix update so we took the very rear part out everything looks good the diff is nice and clean that's the clip that disintegrated in the other transmission no that's a different well but well that's that one is a spring but this one is whatever same and i think the Subaru updated this one on the newer diffs so this is a 98 99 uh so this is just a c clip well it's similar it's different but it's similar so in the other one what happened was as it was dragged by this uh genius tow truck driver this is what was missing in the other one those big chunks that's these guys here these are this is a spider gear and this on both sides was missing basically so anyway so that that's that so uh in between the case and the spider gears there are these i don't know column washers so this is good all the gears look good we're not even going to worry about the uh any of the bearings because we would have to adjust stuff and whatever and we went through all the gears on this one and we do have one and two which is this guy here so it's actually pretty clean inside we're going to take this scrape this gasket off get a new one we took these out for no reason so look who's going to put these back now and the problem lays with this guy here this is this is your lever that goes outside this goes right in here and we were having issues would not go slide this way we would have the reverse and fifth third and fourth but no first and second okay so it would just not twist that was the main issue so this is on the outside of the box okay this goes in here actually like this way this piece slides onto this shaft and this guy goes in here right and this is what uh springs back this is the spring that makes your gear stick stay in the middle as you can see it's not in the middle well as you look at it like that it will push in this way but it will not this way anymore so we're going to take this apart there's a c-clip here see what it's what's inside and if this is not going to work out then we may end up taking the other one out and try and see if it fits in here or just we're going to have to buy a new one basically that's you know that's probably what's going to happen okay a little update I did take this apart there is a c-clip all of this comes out there are two springs inside one big one in the tall one so neutral fifth reverse or neutral and also third and fourth and then first and second this will have to be spring loaded because as you look on the old one or the 06 there's no play you know to go to fifth and reverse or second and third first and second there's no play at all this part of the housing is different this this guy is over here on the 98 update you do have to take the the middle case off to get to the shifter take that out and here here it is then two screws one 14 here two 10s here and then from the inside you can kind of push it out right you push it out and this is it so you see the difference see how this one is in the middle and this one is not like there's stuff missing or it should be at least you know pushed in this way we could just use this one but we you know we kind of worry that this because okay this and this these two stay in here right this one is from this one and this one is from this one this slides as you you know try and select move the gear lever up or down and so this thing slides back and forth and this one is much wider than this guy as you can see and we worry that I mean they are almost identical if we were to use this one or this one on the 98 then this sliding it's not so easy you have to trim this down tiny bit and widen it yeah most likely widen it so this as you can see as you you know select one or whatever gear you want this will slide out right almost out of it so this the length of this ensures that you're staying you know doesn't slip out on this one and it could and you may not be able to push it into this groove right groove whatever and then you know go back come back to neutral so this could be a problem and we can't use this shifter because it's totally different this one works like that you know totally different so yeah so we're going to figure this out and we're going to do another update okay so this is a 99 2000 rs that's how these this mechanism looks like inside so what we're going to do we're going to kind of risk it what I talked about just now so this is the 06 it's already in fits right in and now you can see see it going back on its own and then we gotta hold this it okay see that's the spring working this way and that's the other way so this is this is good it should stay in there we're gonna put this back together test it see if this guy here will stay in there that's that's the worry this guy will stay in here okay so while Lucas is torquing down the transmission which is 12 mil bolts go 18.1 18 or where I just do 19 foot pounds of torque plus or minus 1.4 so we can just do 19 and then the 14 I know it's just a 10 mil but it's really the 14 mil bolts bolts go at 29 and I have been working on this part of the shifter so this goes in and slides more easily okay so I'm probably gonna do a little bit more filing with this little file here I mean if you ask me this is probably okay but just to be safe a little bit more I also rounded up the edges tiny bit here we got a clean case that's it for this one thanks for watching see you soon
