I am expecting shift and it does not happen

Good evening.

I would verify that the TPS sensor is working correctly as that is the sensor that tells the module when to shift.

Also, when was the last time you changed the oil/filter in the transmission?? it could have a partially clogged filter.

Okay, you have covered the basics.

These transmissions are known for valve body issues. You will need to have someone check it for you to verify it is just the valve and not an internal failure.

Roy

Yes, that is assuming it is the issue.

NOTE: The oil pump and valve body are removed as an assembly.

1. Disconnect battery ground cable, then remove battery, battery tray, and remote air cleaner.
