Will a motor & transmission from a 1998 intripid with a 3.2 motor go in a 2001 intrepid with a 2.7 motor? will that bolt up & work without having 2 change bunch of wiring harnesses & stuff?

I am not positive, but I would initially say no. Chrysler set all important modules to the VIN of the vehicle at the factory. There is no way to mix and match tings like the BCM, ECU, TCM, or even the SRS module. They all communicate with each other and if one of them is from a different vehicle then the whole car will go into limp mode. Physically one will take the place of the other, but without transferring all modules with the engine and trans it will not run properly.

2001 dodge intrepid 2.7. Code p0605. Changed tcm started car no service engine light. Pulled out but wouldnt shift into 3rd or overdrive still. Service eng. Light came back on now what do I do?

I can't remember what a PO605 code is off-hand, but I do know that it is a PCM code, and not a BCM code. There are 2 different computers.

42Le trans. will not shift out of ow gear need to locate TCM

If you are looking for the "TCM" it is pretty fair to assume that you have not yet scanned your computer network for fault codes. How do you know the problem is not being caused by something simple like a speed sensor? Just asking!

There is no "TCM" on a 2002 Dodge Intrepid. The transmission is controlled by the same computer module that controls the engine. It is called a "Powertrain Control Module" or "PCM".

What do i need to replace to fix error code p0700 on a 2002 dodge intrepid

(DTC) CODE # P0700....Transmission Control System (MIL Request) Translation: Transmission Control Module (TCM) Malfunction or Failure. P0700 Information Code The Transaxle Control Module (TCM) monitors the malfunction of sensors and actuators relating to transaxle control. If any malfunction is detected, the TCM informs the PCM by sending a signal (P0700 code). P0700 means that a code has been set in the TCM. This code is for information ONLY. If this code is present, check for transaxle codes. So basically, the P0700 code is telling you to check the TCM for a transaxle DTC. The TCM can not turn on the check engine light so it has the PCM do it.

I hope this helps....let me know if I can assist further !!

My 1999 dodge intrepid is stuck in low gear code p1768 is what i am looking for

Dodge: Relay always off (relays are stuck open) Dodge: Relay always off (relays are stuck open) Dodge: Relay always off (relays are stuck open) Dodge: Relay always off (relays are stuck open) Dodge: Relay always off (relays are stuck open) Dodge: Relay always off (relays are stuck open) Dodge: Relay always off (relays are stuck open) Dodge: Relay always off (relays are stuck open)
P1768 TCM (tranny control module) relay output always off
Okay what it means is that the PCM (engine computer) is not seeing the relay for the TCM
turn on. Can be as simple as a new relay, should be in the fuse panel next to the battery under the hood, switch if you can with another identical relay and see if it makes any difference, If it doesn't then you probaly have a broken wire somewhere in the harness between the PCM/fusebox area on the drivers side .

I have a 2002 Dodge Ingtrepid with a P0700 failure code. They said its the Transaxle control module. Can someone please tell how to fix this problem?

P0700 is a genetic code for the TCM has lost data connection from the transmission. Check all the fuses and wire harness to the TCM from the transmission. If everything look fine from the transmission to the TCM, then the TCM may have gone bad. One way to find out if it's the TCM is to go to a good transmission shop that can test drive the car while it's hooked up to a scanner which would indicate if it's the TCM or the wire harness or transmission it self. Note: one of the biggest flaw the intrepid have is that the wire harness to the shift solenoid is in the transmission, surrounded in the transmission oil which corrode the wire harness. Good luck and most transmission shop will trouble shot this free of charge.

2002 Dodge Intrepid- check engine light came on gave me trouble code PO700?

This code indicates an automatic transmission control problem. The presence of this code means that the transmission control module or TCM has detected a fault and relayed it to the PCM. It could be a TCM related solenoid has failed or is damaged or the TCM itself could be faulty. Best wishes.

Where is the tcm for 2002 dodge intrepid people say behind the driver side headlight but the dealer told me that was the pcm not for the trans. so what is the truth i know that the tcm i bought is smaller...

I too have a 2002 dodge Intrepid, after 10 minutes of driving the car, when i make a stop it won't shift properly, in order to make it shift, i have to turn the ignition off and back up again!
If anyone can help me locate the TCM that would be great.
I'm ready to drive it off a cliff
Thanks in advance!
