I bought my 96 Dodge 5.9 3 months ago and after driving a month the transfer case went out. The guy I bought if from said he could get one cheaper than I could. So I waited and waited finally get new one in and there is no place to plug the speed control sensor into. It would only go into 4L so they put the truck into neutral so when we took the original t case out it leaked out a bunch of trans fluid from transmission. It does drive forward and reverse but it's like stuck in first gear and won't shift is there an adapter for the speed control sensor? It's a 2001 t case that I was given. I do not have the t case number because he took 5he old t case made adjustments or rebuilt with new one I am not certain. He dealt with boyfriend who is now ex boyfriend. And the guy I bought it from won't talk to me.

 

You got the wrong transfer case installed. If you have a '96 Ram 1500, you will need a 231 transfer case from a '94-'97 1500. If you have a '96 Ram 2500, you will need a 241 (either DLD (light duty) or DHD (heavy duty)) transfer case from a '94-'97 truck with an automatic transmission. You should be able to find one via car-part.com, as they list inventory of salvage yards.

 

Technically correct but the speed sensor on the transfer case has nothing to do with the transmission operation. This is still the 4xRH generation and the speed sensor is only for the speedometer. Was transmission fluid added after a bunch leaked out ?

 

DerTruck is correct regarding the transmission issues. I only addressed the transfer case issues you were experiencing and didn't really read into the transmission issues you mentioned. Another question - do you have a check engine light on? If so, what are the codes stored in the PCM (these can be rendered by connecting a OBD2 scanner to the diagnostic port under the dash)? This may provide additional clues as to what's going on.

 

IME if you let most automatics sit with no t-case you'd be surprised how much ATF you lose over time. It's deceptive because ATF is relatively light and somehow seems to just "vanish" -- at least relative to the actual amount lost.

Make sure trans is full in N, parking brake set, engine idling. Preferably at operating temp but if it's that low I wouldn't run it longer than necessary with very low levels. Get it close (say, bottom of "safe" zone), get it warmed up, then do final checks. Do try not to overfill - ATF expands with heat

 

You still have all the various ranges in the t-case, it's just the shift patter changed. See if you can pull a build sheet for your truck from here, it should tell you what t-case your truck originally came with. You need a t-case from a 94-97 truck, of the same variety.
