So I just bought a used 2007 impala for around 3k with 241k miles on it, all was good until a few days later however I was driving and stopped at a red light all of the sudden no sound or nothing but my car wouldn't drive. I switched it to second gear and was able to make it home and upon some more investigation 3rd Gear and Drive act as neutral now and I can only drive in 2nd, 1st and reverse. I tried adding ATF, switching the TCM, Changed some fuses thinking about resetting the new TCM because I got it out of a USED 06 impala from the junkyard. Idk how long it was sitting without power. Anyway still no dice. Anything else I should check before pulling out the Trans and trying the solenoids? And no there is no leak.
