Anyone have experience with this code??? Transmission Control System Malfunction. My car threw it twice in a week. It has only happened while in autostick

P0700 is telling you the trans has a code. Need a reader to get the actual code. Even the cheapo / free reader at the auto parts store will read the code.

Unfortunately in 2002+ it's solenoid pack related 90% of the time

Get the codes read and go from there.

Autostick merely substitutes for the signals that the PCM would otherwise send to the solenoid pack to control the transmission. The solenoid pack and transmission functionality operates the same whether in autostick or not. Thus most codes below the DTC P0700 are independent of whether autostick is being used.

And always do the valve body with the solenoid pack. You don't want to go back in a second time.

Does speed sensor control make any sense? That seems to be what a code reader says it is.

We have seen speed senors cause P0700. There are 2, input and output. If the output sensor is failing typically the speedo is erratic or inop.

thanks bob. its not the output, so it must be the imput. I have to get the car inspected next month. I plan to have them replace that sensor then. Since I've never had the solenoid packs replaced, I figure I should have them do that too. Would u agree? I don't know if I could do either, but I really don't t have the time. Any reason I should not get the parts from Rock Auto????

If you do the solenoids best bet, is an OEM reman comple valvebody from dealer. Although you can avoid that after looking at built date code on your valvebody. Some only need noids, but this can only be done after removal.

What was the actual code P0XXX ? That would drive my decision.
Due for a fluid and filter change ? Pan would be down, so that would be the time to swap the solenoid if that is indicated by the code.
Solenoid and OEM Reman valve body is recommended if and when the time comes.

(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 cannot turn on the check engine light so it has the PCM do it, which can only be done with a diagnostic scanner. The self retrieval method for Chryslers with the ignition key will not pull up the specific transmission fault codes in the TCM.
