Hello, I have a 1999 Pontiact Trans am, 87,000 miles, (5.7L) V8 with a 4L60E automatic transmission. Yesterday when I tried to drive it the transmission would not shift gears. It was about to redline in first gear so I let off the accelerator and it dropped to around 2500 rpm and when I then reaccelerated it shifted and then the same thing happened in second in which it began to redline and was not going to shift until I let off the gas and let the rpm's come down and then reaccelerated. The transmission fluid is clean and full. It has a clean filter. Where do I begin looking for the problem? Could it be electrical or a solenoid? Or do you think it could be mechanical? Do I need a rebuild or just a repair? Please help. Thank you.
