Did a little searching and I found this on another board, I wasn't aware 32RH had an electronic lock-up version. Can you post a pick of the wiring connection location/type.
1)The TF999 3spd auto was used in CJ & YJ untill 1990,
2)Then in 1991 to 1995, the TF999 was tweeked slightly with an auto-lockup converter and re-named to 32RH
3)In 1997+ the auto-lockup converter was replaced with a computer controlled lockup converter (like the one Flexy mentioned) at this point, the trans. was still called a 32RH.
