Puegout transmission

[pederl]

I know it's spelled wrong. I have a 1989 4.0l 5 speed, I need to change the transmission fluid, do we have a page to show this tran and specs on it? Thank you.

I just call it a BA/10, or junk.. the guys at a auto parts store should be able to tell you what you need.. sry i wasn't much help

You need a Haynes repair manual.

What do you need to know?

 

Don't believe the first gear spec everyone seems to use,

like 3.39:1, or something.

 

I've had 4 BA 10-5's,

the early 87-88's I had were ~4:1 first gear,

the 89's I had were ~3.75:1

 

When my 4wd 10-5 finally died,

I grabbed a 2wd 10-5,

swapped the 4wd output adapter in place of a 2wd's tailcone,

then cut the output shaft down to fit.

(2wd output shaft is splined all the way down to the speedo gear location).

 

The later 3.75 10-5's seemed more durable than the earlier 4:1's,

I changed the gear oil often, and extended the breather tube to keep the pukey from puking gear oil at highway speeds.
