94 caravan Tranny problem

Hi, I have a 94 caravan AWD, I have been having some problems with the trans shifting funny, I was heading out of town and it would down shift out of over drive then back in, and when i got to my destination doing like 25 to 35 it still was like around 2500 to 3 grand rpms, I reset the ECM and it seems fine but alittle hickups on the way home but not as bad, It seem to happen when the temp is in the single digets. But not to sure, TPS? I have changed the filter this past summer and put the right fluid in...so.....Help please

Your transmission is engaging into what is called the LIMP MODE. This mode is to help from further damage to tranny.

Check all the connectors to the input and output sensors, the solenoid pack, and the TCM (Transmission Control Module) which I believe is located on the passenger side firewall, for corrision and or looseness. Also check the electrical connector going into the top of the solenoid pack for any oil or moisture. Is the solenoid pack leaking any fluid??

If all appears fine you may want to install new input and output sensors, they are about $16.00 a piece at auto parts stores.

Here is a site with a photo that shows location of all the tranny compotents:
