pederl Posted October 26, 2011 Share Posted October 26, 2011 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. Quote Link to comment Share on other sites More sharing options...

jpnjim Posted October 27, 2011 Share Posted October 27, 2011 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.
