I.E. cmp sensor/cmp performance?

Also
pulled
U0101. He says this is failure to communicate with transmission control module.
Thoughts?

Said that it ewally could be part of the problem. He did not seem convinced.

I have just posted in your other post about my 06 HHR with a U0101 code. I had to replace the TCM trans control mod. $156.00 with tax, 1/2hr labor for reprogram of new mod.

 

Thanks! I'll take a look.

I'll bet that if you go to your local Salvage Yard, you can get it in hand for around that $55 Ebay bid. Seems to be an incredibly popular GM item, just about every GM model with a 4 or 6 built in the 21st century.

 

the P0013 & P0014 codes are covered under this posting - https://www.chevyhhr.net/forums/how-tutorial-library-21/camshaft-position-actuator-solenoid-valve-replacement-w-pics-p0010-11-p0013-14-a-28779/

the symptoms are CEL on - codes P0010/11/13/14 - hard shifting of the tranny.
