you can get guide from many sites.. i know few
error codes/ fault codes, wiring diagrams, schematic diagrams, torque specs, engine info, switches functioning, assemble, disassembly, complete refurbish, repair, installation every single thing is covered
within seconds u can get the access and it's totally illustrative complete

how much does a trans control module cost and what is necessary to complete replace

The TPS ( THOTTLE POSITION SENSOR) tells the engine computer and trans how far you are pushing the gas pedal. Its mounted on the side of the thottle body. It will make the engine surge if it is failing. Have replaced this part many times for this problem. TCM (TRANS CONTROL MODULE) control trans shifting. The tps is and one of the input sensor for shifting.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

po700 is the code in the pcm,telling you there is a code in the tcm( trans control module) po605 is a internal tcm error replace and program the trans control module

The short answer is no

the list of replacement parts would most likely exceed $8000, trans, trans control module, engine control modules, complete engine & trans wiring harness, trans, modifacation to the firewall, complete pedal assemblies, and the complete engines were different if look at the specs at dodge.com

p0700 is a generic trans. code, so the problem if it is in the trans. would require further trans diag. so i would scan trans specific codes first. but in most cases when a chrysler tells you it is an internal controller fault you can believe it. just make sure which controller it is telling you has a fault!

Bob your trans does not have a gov. it is all electronic, will be glad to help on anything in future if needed. thank you

I have a 1993 Caravan with a 4speed trans.. I had to replace the transaxle control module. I paid $50.00 for it at a auto salvage yard and It corrected the problem. My trans would either go into limp mode or act like it was in Neutral.
