CJ7 manual tranny fluid??

[Yotacrazy]

1983 CJ-7 T-5 tranny, what fluid does this take..The manual stated a "Chrysler manual lube part # so an so"...I would assume since it's a T-5 that it would take ATF but just not sure..Thanks

[mossrocktj]

so is it chicken or fish?

Torch off.


Hey crawl under there pull the fill plug, stick your finger in and if red its ATF, if it brown and smelly like a girl named shelly then it's 90w.

[trkklr77]

do you know what the "A" in atf stands for?

put it in if you want, its not going to hurt it, or some 80-90 gear oil is my favorite.

just so you dont think im full of it, a 205 tcase is listed with different fluids for different vehicles, runs any thing from 10-30, 80-90 and atf depneding on the vehicle manual.

The issue is, he changed it a few weeks ago and used what he thought went it but doesn't remember what the fluid looked like when he drained it..He did all the fluids that same day..PS..I know the difference and how to tell, just need to know what it's supposed to have in it..Thanks

I know you're not full of it and I sure as hell know what the "A" stands for..Borg Warner T-5's typically take ATF is why I asked.

The vescosity of the chrysler oil is similar to ATF, too bad IIRC it costs 9 bucks a quart.

There are issues with not using the chrysler oil, it has something to do with dergents or stabalizers or some other additive. Not using the recommended oil can and most likely will carrode the bronze syncros. I've heard this happen in the t-5 and I've seen a 5-speed muncie (similar to the Getrag 260) in a chevy truck blow within 500 miles after the non-GM oil was put in.

Unless someone can say they run their t-5 with the non-Chrysler oil and it has survived, i would go with the dealer recommended oil.

Better yet, throw that t-5 on the curb and at least get a ax-15...or a muncie 420

I appreciate the knowledgeable answer, unlike others..I know the T-5 in our street rod is from an S-10 and we run the GM fluid for that exact reason..This isn't my truck, just trying to help a buddy out..Thanks again

Using synthetic 75w90 and it works much better on several vehicles that synchros where wearing on .

I ran 75/90 for 8 years no problems Sold it when I repowered and the new owner reports no problems. There are 2 versions of the T5 and some will use ATF. As I understand it, it depends on your mainshaft bearings(taper or ball) and the variance was in the '82-'83 series CJ's

That figures..It's an 83'..Thanks for the info..

[grljeeper]

Ditchpig is giving you a good option or you can run ATF does not have to be Chrysler's

[conefoot]

I've been told that Chrysler tranny fluid is ATF#4. Certainly in reference to AUTO trannys though.

You can use a 50/50 mix of atf and mineral spirits..

Excellent, that's what's in it now..Appreciate all the help...

[ElGuapo]

if it is a world class t5 dextron 2 transmission fluid
if non-world class t5 like mine you could use 80w-90

[BildoStyle]

mine is about to come apart and the 75/90 will be put in. I lost 5th and rev is messed up, fells like the linkage is broke or something similar. Anyone have an ax-15 for sale?
