[Brightyellow69rtse]

what gear oil do i get for it and how much? ill be picking the motor up next week so im trying to tie up all the lose ends

[Brightyellow69rtse]

i was unaware you put additive in the tranny. i knew the dana took it. thank you sir

[Chryco Psycho]

I messed up , 4 qts of 89-90 oil , no additive , I was thinking diff not trans 

[A383Wing]

my A833 calls for 140w in it

[Brightyellow69rtse]

ahh ok so anything is that weight is fine then?

[Chryco Psycho]

do not use the synthetic gear oil , if it is GL% it is too slippery & the syncros will not grab , 80-90 works great , any make , the factory service manual says you can use ATF but I would only recommend that in very cold climates

[Brightyellow69rtse]

i got 2 quarts of plain old advanced auto parts 80-90 gl5 gear oil today. 5 bucks a quart. should be good right?

[Chryco Psycho]

should work , but I screwed up , you need 4 qts as I stated above .

Oldest myth in the book, synthetics for synchromesh transmissions are formulated with friction modifiers.

I use Red Line 75W-90NS or Red Line MTL in the 833 and it shifts smoother than 90 or 140 and is less noisy than ATF.
