Changing Manual Transaxle Gear Oil

The process in this video applies to all import FWD/AWD cars. Honda, Mitsu, Nissan, don't matta...

Oils and torque ratings specific to the AWD and FWD turbo Eclipse are outlined in addition to tools to do this job. This is considered elementary, yet most people have a service center do this for them. Like many of those people eventually learn, it's best to do this yourself. If you've ever wondered how to do this, here it is.

Its the fill plug I can't find I have to assume its on the side but the one I can find isn't even close to 17mm

@RSXKane The fill bolt is on the front of the transmission (if you're standing at the front of the car). It's oriented about 8" up from where the fill bolt is, and should be directly to the left of the shift fork.

The bolts you don't want to risk taking loose are the 3 14mm bolts lined up with each other. There are spring loaded ball bearings behind them. The fill bolt is by itself.

I'm trying to do a fluid swap but I can't see the fill bolt I've lookes jacked the car up and looked and there is 1 bolt but its really small and pretty low on the transmission the car is a 97 gst

[Jafromobile]

@RSXKane The drain bolt on manual transmission cars should be at the lowest point of the transmission case when the car is level. It's a huge bolt. 24mm or 15/16" I think. I have another video about AWD fluids that covers this in less detail, but in 1080 HD. It's in my Trans & Clutch series.

I have an 87 nissan nivara 4wd manual. Changing gears up is fine but changing down in2 2nd and 1st is really hard, i really have to force it in.

Could this be because my i need to change the tranny oil?

[Jafromobile]

@orgasmoman69 Yes, absolutely. Or it could be low. BUT... If you change the gear oil with the recommended fluid and it still shifts like a Choda Boy, that indicates the syncro's are worn. Changing to a different fluid might resolve the issue.

A small amount of friction is actually necessary in a manual transmission. When you shift, it's what lets the syncros do their jobs to change the speeds of the gearshafts so you can easily shift. If the gear oil is too slippery, they might not work.

[RustyXIII]

Since you change yours often, this might not apply to you, but people doing it the first time should ALWAYS loosen the fill plug FIRST. Finding out that the fill plug is stuck/seized on tight after draining the tranny fluid can be very annoying to say the least.

@Dosalt I'm positive that it is possible to remove any car's drain/fill plugs. Perhaps you've run into an aluminum oil pan? If so, the process is still the same, but you have to be careful not to strip the bolt or the pan when installing and removing the plugs.  Those pans are expensive to replace. EricTheCarGuy covered this sort of thing. The way you asked your question sounds like you've found a bolt you don't have a tool for, like a 10-point socket or a Torx? You'd just need the tool.

[RSXKane]

@Jafromobile i finally found the right bolts but it looks nothing like yours the drain plug is on the back side of the transmission but it didnt really fix my issue it helped a little with the new syncromesh oil but some times its still tough as hell to get in to first

could this be a broken mount? i think perhaps the one on the back side of the motor is broken and maybe everything is miss alined by a small amount

thx for the help before and any help u can give me

[chris2756832]

I think my car doesnt have much gear oil left, i have the same car as you except its a GST, it won't go into gear anymore meaning it wont move, i had a "mechanic" tell me it was the slave cylinder, which i replaced already and it still doesnt work, I'm gonna try to see if it has oil or not, i know metal shit is gonna come out because when first learning to drive standard i grinded the bears a bit too much

[gerjaison]

Looks efficiently done!

[MrDumess]

good advice man im going to do this on my 1999 eclipse only feed back in my opinion is clean ur working area u dont want your parts with dirt and shit
