 What's happening YouTube? Thanks for tuning back into the channel today. As you can see we got some more Duramax goodies coming right your way After doing a couple of the performance upgrades on the last Duramax video We've kind of found a couple of little shortfalls with it in the first one Obviously, we kind of knew this going into it is going to be the transmission So we're going to do it a little bit by little bit. Eventually. Yes We will go to a full trans build on this thing for you guys and we're going to show you every step of the way So the first little upgrade that we're going to be able to do for you guys is we're going to be putting a shift kit in there This is a trans go. I believe it is a SK Allison trans go junior shift kit It's got a couple of valves in it got a couple of springs that we're going to change out It's really not going to be that hard We're going to show that even you know the DIY we can guy can get this kit all done It's not that hard at all. So stay tuned. So what exactly is a shift kit and what does it do for this transmission? Trans go says this is supposed to fix and reduce the driving complaints such as a Couple of different codes when it goes into neutral under high boost conditions The two three shift the three to four shift under high boost is you know has issues They say that you'd also see it stuck in a gear Sets different trouble codes and it's supposed to just in general shorten up your shifts and make them nice and crisp That is so that's what I'm hoping it'll do It'll be able to hold those clutches a whole lot easier be able to keep me from you know burning this thing up too fast Like I said, I know we're eventually going to do the trans full rebuild and build on it But hopefully this will get us through to that time and give you guys an idea of what it'll do So first off we're going to have to be draining the fluid out of here now because a couple of months back I did change out the filter the fluid and everything on the trans. I'm going to be saving what I have in here So the first thing we're going to need to get to do is a 15 millimeter to Drain our fluid out of the Allison trans here They do make it nice that they do have a nice Drain plug right here to be able to drain everything out for you So you don't have to you know drop the pan get this super big old mess everywhere So that kind of makes it nice for us to be able to get started So we'll get this drained out and then there's it looks like we'll see four eight 12 or 13 of these 13 millimeter bolts to be able to drop the pan here So we're going to drop that so we can get access to our valve body There we are guys we got our pan all dropped now We've got access to our sump filter which we will also replace because I didn't replace that one when I did the fluid and filter change We're gonna get the little gasket off here. The factory gasket is a nice hard rubber gasket with Metal rings around where the bolts go so that is actually going to get cleaned and reused So let's just set that one off to the side and then we're going to get this sump filter off Doesn't look like it's gonna be too bad And then I'm gonna put a picture up onto the screen of the bolts that you're gonna want to remove to be able to Get that valve body out So now that we dropped our sump filter off now We're gonna be taking off our harness and we're actually gonna be leaving the harness in the vehicle It's kind of just gonna you know hang down back here and we're gonna be able to take all these clips off So you've got kind of one hidden up here two three four five six solenoids one solenoid is up here One of the sensor connectors is this blue one right here and then the larger Looks like six or eight pin is here on the back side So we're gonna be taking all of these off and then this whole harness will just kind of swing back out of the way Also there guys, there's these two little tabs that are right here I'll see if you can see it right here that hold that harness connector into place And it's actually held in by these little pin clips We're gonna put those back in because they also hold those solenoids into place So they're up on your screen. I've got a picture from the Allison manual and the highlighted yellow bolts there are gonna be the ones that just hold the valve body into the case The other ones we're gonna take apart later once we get the actual valve body out But right now we're kind of just taking the valve body down out So we don't want to have to take out more than we really need to and then back up here We've got the two other gold color bolts right here that hold the spring retention In for the shifter, so we're gonna take those out first and Then take our spring retainer here for the arm out now the pin there in that arm As we're lowering it there is a pin that goes into the little shift arm Make sure you get that one pulled toward the driver's or the passenger side out of place You can see kind of right here that little shift arm. That's gonna be pulling out towards the passenger side So now that we got the valve body out here on a work surface We're gonna be taking out all the rest of these eight millimeter bolts except for we don't need to take out This little gold one right here There we go guys the two halves are separated It took a little bit of prying because there is dowel pins that go on to the bottom side here I kind of like to leave all these bolts into place But those dowel pins you'll kind of just have to wiggle back and forth to get everything separated And so we've got the upper the lower and our plate So now what we're gonna do we're gonna work on our upper case half here We're gonna pull out one two three four five of these bolts out of place the one that has this tube That goes across here. We need to pull this plate and this connecting tube up out Just takes a little bit of prying So there's our crossover tube And then this plate right here will come right up out of place And that's actually what holds in these two solenoids that we're gonna be working with so then There's gonna be two springs that are right here and you'll kind of we want to be very careful also because there's two Plungers probably won't be able to see but right here. That's right underneath those springs those plungers push up on the springs So make sure we don't lose those So now what we're gonna be replacing is we have our a Shift a solenoid valve in our B shift solenoid valve Without flipping it all the way over and losing all of our screws We're gonna just gonna set it up on end here to be able to get access to these valves And they're gonna be a little bit tricky There we go actually just use the little Screwdriver here grab the end. So that's gonna be the one end to the valve on the A side There should still be a valve in there, this is just the end plunger and then there is the B One as well And then these what do you think the tolerances are that they'll just fall out? So we're gonna just gonna kind of put it down onto the end here and We'll get these to fall by prying just a little bit to get them to fall out Just like that There we go so next we're gonna be kind of drilling out some of the relief the drain holes in our Spacer plate right here the kit comes with this point one two five inch drill bit I believe that's close to like eighth inch so on the actual plate here you will then flip it over and it will be this tiny hole right here and That tiny hole right there See how close we can get here It shows it very good in the instructions, but those are the two holes. So we're gonna drill those two out Yeah, we don't want to get any fine metal in the transmission So we're gonna clean these off really good And then we're gonna get a little bit of just scotch right pad or something just to make sure we don't have any Edges or anything like that and we'll clean this thing all off with brake cleaner then as well All right, so in the kit it comes with a pair of valves It comes with a pair of larger springs a pair of smaller springs as well as a couple of check balls Now these check balls nothing came out check ball wise when we took all this apart This is all added in there. So on the B side right here. There is gonna be one with a ridge to it So we're gonna put our check ball in we're gonna put our small spring Into the end of that and then our large spring over that one We're gonna put our other one together to this one's gonna be go into the B valve The other one is gonna go into the a valve now This is the tricky part in that this spring side is what goes into there first So we're gonna kind of want to hold the valve body up with a partner And then be able to slide these up into there get a little bit of coating of Transfluid just to help them slide up in there a whole lot easier and then we're actually gonna reuse the end little Retainers that's gonna go in there as well that one will go into the B And then that one will be there for the a so let's get these put in So now that everything is set back in there nicely into place We're going to go ahead and put back in our two retainers The A side is looks like it has a spring on it and the B side does not Just like so guys All right, so now we've got all of our valves seated in there with our end plungers when you push on these if you Have everything seated correctly the a one here on the outside is going to have a harder spring press than the one On the inside make sure there's no binding no, you know little harsh grinding areas that they press in nice and easily So we're going to be reusing the same two solenoids right here We're gonna be putting them in and putting everything back together just as we just took it apart Looks like we're all seated back together now when we go to tighten these back up They all of these 8 millimeter bolts are going to be evenly tightened Usually what I like to do is start in the middle and kind of work around in a circular pattern going out All of these are going to be torqued down to 9 foot-pounds So we'll get to torquing these All right now when we go to head and put this thing back up into place like we said before that shift arm You got to make sure you get it into the correct area on this shift cable or the shift area into the notch And then align your dowels get it set back up in there and then we'll start putting some bolts back in and Then actually once you get all of these up into place These bolts are going to be the same exact foot-pounds as it was when we took the two halves of the valve body apart 9 foot-pounds to put all these back in as well So next we're going to fill up the trans back up with the fluid that we took out of it check it We'll probably have to add another quarter So right around there now trans go they also say that you need to do some kind of a trans Relearn so their version of relearning the trans I'm a read-off sheet right here for you So start by making at least six that sets of light throttle up shifts through the years next make six sets of shifts at one third throttle then half throttle then three-quarter and so on Treat down shifts the same way by starting with light throttle and working up the full throttle when the shifts are quick and smooth Hit the tow-haul button and start over with the relearn So that sounds, you know pretty simple at that during the relearn expect some clunks bumps and or short flares Especially during the three four shift bumps and flares are normal during the relearn always do the relearn So seems like it's pretty easy Relearn usually takes about two hours worth of driving to fully initialize So I guess we're gonna have to go out driving for a little while. Oh darn So we'll go do that after we get her all filled up here So now after you get the whole vehicle filled up with fluid mine took about one extra quart So after you save all that it'll only take that much that you lost You want to make sure you get it up to full operating temperature on the transmission and on these diesels It takes a little bit of time So you want to get it up to at least over a hundred hundred and fifteen degrees on the trans temp Before you start doing anything then you can either a start to do the relearn just like I said They for them to do the slow stop style relearn or if you have access to a scan tool They have what they call a quick learn function on the scan tool We'll which it'll run through a couple of the solenoids get some of the air out of that valve body and Just allows it to go through a learn process just a little bit faster So now that we've got the trans up to temp We're gonna be doing a couple of normal quarter throttle pulls on it and we're gonna see how much better this thing shifts This one's gonna be a quarter throttle pull Not too bad at all. The shifts are actually a lot nicer, especially that two to three shift It's a whole lot crisper now that I you know have been feeling this thing with the power that it has now So now we're gonna get up and try a half throttle pull very nice Compared to what this trans was doing before I had in all this power to it without having you know The proper shifting and the proper thing pressures for the trans it was struggling a lot. This is a lot nicer guys Now for our three-quarter throttle pull That one to shift had a little bit of a flair to it But when it actually engaged into gear it was very solid it held the gears really well It worked pretty nice. I think we're just gonna have to end up driving this thing a little bit more They usually say these Allison trans like to have a couple hundred miles in them before they really start You know learning and getting in back into their swing before this So we'll give it a little bit of time before we do any like real hard pulls on it After driving a little longer I'm just falling more and more in love with this truck with all the power adders that we're putting on to it We're just you know finding those little short falls here and there Which we kind of already know that the Duramax has a couple of shortcomings when it comes to adding power to it So now when we're at like full pull at full boost on the throttle and like fourth fifth gear We start cutting out check engine light comes on and we got a low fuel real pressure code So we're gonna be doing a couple of more small Upfits here and there to be able to get rid of those and like so we're not gonna go into just a massive quick build All of a sudden we're gonna go in through it step by step Just to be able to show you guys the process and what you guys are gonna find in each step along the way Well, that's about all I've got for you guys today Appreciate you guys tuning in.
