Hello and welcome. My name is ***** ***** you for visiting the site, I will be happy to assist you today.

.

That sounds like the trans range position sensor is bad.

The Transmission Range Sensor (TRS) communicates Shift Lever Position (SLP) to the TCM as a combination of open and closed switches.

.

I can get the test instructions for it and put it in a PDF file, (it is rather large) and send it to your email address for as little as is allowed.

.

You will just have to accept the additional service offer and ENTER your email address in the “ENTER CONTACT INFO” section so that I can see it, Thanks

where is the range sensor located on this trans?

how can we be sure its the range sensor and not the pcm? i dont want to have to drop the valve body to replace the sensor if thats not the problem
Expert:  Jerry replied 1 year ago.

It is above the valve body, (see diagram) and it can't be tested by probing with a volt meter but can be tested with an ohm meter.

.

Each shift lever position has an assigned combination of switch states (open/closed) that the TCM receives from four sense circuits. The TCM interprets this information and determines the appropriate transaxle gear position.

but to remove it, you have to take the valve body out..correct?
Expert:  Jerry replied 1 year ago.

Yes, which is why the file is rather large. It includes the sensor, the test for it and the valve body, thanks

The TCM interprets this information and determines the appropriate transaxle gear position and shift schedule.
