Awhile back my trans was stuck in 2nd mode, it still is. I know that I may have missed something but I have redone all the grounds and even added some new ones. I have replaced all the solenoids inside the pan and replaced the wiring harness. I am at a complete loss now why it is still in second mode. Is there any mechanical issue inside the trans that could cause it to stay in second. There has never been any code stored for a reference where to start and yes I have checked and even replaced the TPS. It will shift if I ground the 1-2 and 3-4 solenoids.
