Been fighting this thing for 2 weeks. Would appreciate any troubleshooting advice. The vid link explains it better than i can in text. Thanks for any help.

 

Sorry for the audio. going to work on that...

 

Out of curiosity would a bad hybrid battery cause the transmission to not go into gear? Would disconnecting the hybrid battery then allow it to go into gear off ICE to show that the battery is the problem?

 

Need the HV battery to start the ICE, so that approach won't work. Have you scanned for the voltage of all the modules or the battery pack?

 

13.8-14.2 After i start the vehicle with nothing running.

 

The only gears i can get even with manual is neutral and park. any other way to troubleshoot to see if its not the transmission? Codes arent saying anything transmission related and the problems came on suddenly with no warning. I had first gear for about an hour then after it sat i had nothing and engine rev problems.

 

Probably should continue this here... What harnesses are you talking about on the other thread? Locations would be awesome. I looked underneath the truck while i had it in the air but didn't see 2, only the one, unplugged it and replugged it and it didn't help. Are you talking up top from the battery?

Did a quick vid on the problems with the codes on screen and talked about it a bit:
The volume sucks but its easier than typing it all out.

 

Rear passenger side of transmission has 2 connectors that are twisted on/off. Right above the 4th bolt (from front to back) on the passenger side of the oil pan.
If you can sometimes get the engine to run, is the battery charging during this time? Check the radio for the screen that shows the hybrid status.

Another thing to check is the Aux Transmission Fluid Pump. Can you hear/feel it running while the engine is in Auto-Stop mode? It is the small motor between engine and transmission, just in front of the transmission oil pan. If not, troubleshoot the wiring up to the Aux Fluid Pump control module.

 

i Haven't had this go into auto stop since this all started so i have no idea. and the screen just shows engine idle and doesn't show charging.

 

Any tricks to getting the top connector to go back in? been fighting it for an hour. no bent pins just cant seem to get it to seat in place.
