Van was working fine, lost power to wheels. Gear shift lever works fine, transmission does not engage in any gear (R, D, 2, or 1). When moving shift lever RPM's increase slightly but transmission never engages. Relay appears to work need TCM pinouts.

Hi,

Have you checked the basics? Is the fluid clean and full? Have you checked fuses? Is the shift indicator showing the correct gear?

I attached the entire schematic for the transmission. I had to break the schematic into three parts so you could read it. I did overlap them so you can follow them. Let me know if this is what you needed or if you have other questions.

Also, let me know if you were able to retrieve any trouble codes.


Take care,
Joe

That went out. Fluid level is fine, correct color no burnt smell. Had a P0700 with no other codes. I disconnected battery for an hour to reset all. Same symptoms, no R, or forward engagement. I visually inspected all harnesses and connectors, appear ok. Relay is clicking when key is turned on. Have not pulled wheel well to inspect TCM.
