Sup everyone, like the title says my TCM on my 07 TBSS is not getting read by HP tuners. I just put house of boost procharger on and i was just about to get it tuned when the guy tuning it brought this to my attention.

I never messed with the transmission. I had to drain the radiator fluid if that has anything to do with it maybe.

My shifter is stuck in park also and the only way to get out of it is to press on the solenoid switch or whatever its called at the right side base of the shifter. I think this problem is related to the TCM failing to read. We disconnected battery and TCM plug but it still fails.

Maybe someone had a related problem. ANY help is GREATLY appreciated because I have been waiting 3 weeks to get a tune for my newly procharged tbss.

 

When flashing the tbss controllers you have to do a "write entire" not just a "write cailbration only" or what your describing can happen..

 

HPTuners version 2.24 can now do a write only
