drained and filled up my radiator, motor, and differentials on my 1978 bronco, 400, granny4, part time t-case

question
autozone said :t-case = 80w gear oil
tranny = 50w motor oil
haynes said: t-case and tranny 140w gear oil

what and the heck do i put in my tranny and t-case?>

 

can anyone answer this question for me?

 

try the tranny differential, and axel place. I use 80/90, but I don't think you can go wrong

 

Chilton says 90W for both.

 

Look in the Haynes manual.

 

im just going to go with the haynes manual and put in 80weight gear oil but im glad i didnt go with what autozone said and put in 50w motor oil into my tranny or maybe i should have and the suckers could have bought me a new tranny thinks for the replys guys
