rear end question

scale · 09-11-2002, 10:41 AM

I have a 1991 lx coupe aod and i want to know if i have traction lock rear end. I am needing to know if i need to add the additive to my gear oil when filling. If you have traction loc you need to do this but i am unsure if i do. I think i must have it but i want to double check. Also, how many bottles of 80w90 can i expect to put in my rear end?

Thanks alot guys....

It should say on the tag if its posi or not. It will go somthing like this for 3.08 gears: 3 L 08. If theres no L its not a locking diff.

To find out on my car I wrote down the letters on the door tag and went to mustanggt.org they have a vin decoder and a door tag decoder. One of the letters on the door tag tells the decoder what type of rear end you have assuming you have a door tag. If you already know, check it out anyways. It will tell you all about your car.
