how do you change the tranny fluid on a 5 speed?

[Drummer]

well being that it's spring and i put almost 50,000 miles on my tranny i think i should change the tranny fluid, the only problem is i'm not sure how to just for the fact that i don't see any plug or anything like that. Do i have to suck it out?

There's a drain plug on the lower portion of the tranny case. Looks like a cadmium plated bolt, about the same size as the engine drain plug bolt.

 

I think you can re-fill the case by removing the speed sending unit, as it provides a larger opening.

 

and of course, use the dipstick to check for the proper level.

thanks a lot.

BTW, the owners manual on my '92 calls for specific GM Syncromesh transmission lubricant (not 5W-30 engine oil or ATF).

 

The earlier FWD Muncie trannys used engine oil, but not the Getrag.

[Drummer]

Yeah i know that you can only get it from the dealer or so i was told.

Fill up the trann via the dipstick.......just make sure you can get the dipstick out before you drain!

If you would like to avoid the Stealership for synchromesh oil.

[Bake82]

I dis agree with Kevin. run ONLY GM Sycormesh in your Tranny. It's not THAT expensive considering you only need 2-3 quarts. Go to GM and do it RIGHT!.

 

 

This is one of those things you should use GM parts only.

- Meets GM Specification 9985648 and Chrysler Specification MS-9224.

- Suitable for use in GM manual transaxles and transmissions requiring GM Part No. 12345349 or 12345577.

 

 

My rebuilt 282 shifted excellent on this fluid.

 

 

But as always, use whatever fluid you please.

Every auto parts store I've been to stocks Pennzoil Synchromesh fluid.

[Bake82]

25 a quart? it's like 8 bucks a quart here......thats why I said use GM syncro....

[Drummer]

yeah it's like 8 or 9 a quart pretty cheap for GM.

i use Amsoil Synchromesh. If it's a light to medium-duty use 282, the Pennzoil or GM stuff will be fine.

 

 

Of course, my Cobalt's uses synthetic ATF...weird, huh?

Many manual transmissions require ATF.

i paid $15 for 2 quarts at the dealer

not usually synthetic and it surprised me since most getrags require synchromesh. it actually isn't a getrag, though. the 2.4 and 2.2's have getrags, but the 2.0 has the saab fgp35

It's probably just GM covering their asses. I'm sure a Corvette would run fine on conventional oil yet they require synthetic for the high performance LSx series of engines. Synthetic fluids would be a great idea for any transmission because it's not like the average driver actually changes their transmission fluid, especially in manual transmissions. Even for those drivers that follow the recommend maintenance schedule, transmission fluid change intervals are quite long.

i've heard from some people in the oil business that pennzoil's synchromesh lacks the friction modifiers that the GM fluid has.

 

the stealership here was $14 per quart but only needing 2, it was cheap insurance. plus if you bend up a 1/2" copper line right you just made a huge fill tube that you can stick into the dipstick hole and toss a gear oil spout on the bottle and you're good to go.
