1995 Caravan 3spd

OK I got this Carvan and it only has 1 gear 1st ,no reverse, no nuetral, even when it is in park and you start it it wants to move foward.And it will move in any gear position. So I hook up my Snap-On scanner to pull codes and view data, well guess what no PCM comunication or CCD either. So anyone else run into this? The only systems I can view is BCM and gauges.

You cannot pull any codes from a 3 speed auto , it is strictly a hydraulic unit with no electronics except the feed from the ECM that controls the lockup torque converter . You would only be able to pull codes if you had the 41TE 4 speed auto .

OK but shouldn't I be able to axcess the PCM and view data?

Yes, but it would not tell you anything about the trans, it is not electonically controlled or monitored. Sounds like your shifter linkage is broke.

Depends on what scanner you have , I'm not sure in 95 they had even made it to OBD II which was a standard and at that point it might have been a chrysler proprietary scanner and maybe thats why you can't pull anything .

I have a Snap-On scanner MT2500 one of the best scanners out there in some peoples opinions. I can get into the BCM using the CCD plug under the dash. The other plug on the strut tower drivers side is the one to pull PCM codes.
