Programming of key fobs was tried at a dealer, dealer was unable to get them to work. As for the transmission I wasn't clear so I appologize. The transmission engages, but shifts through the gears very rapidly, going all the way to OD by the time the speed is about 30mph. It also wont downshift if you apply the accelerator to for example try to pass or go up hill. The engine continues to run at the same rpm(about 2200) but the transmission wont engage to a lower gear to accelerate, it will actually lose power. No engine Codes since I replaced the MAP.
The dealership that tried to program the fobs is who told us the BCM was failing. Is a special scan tool required to check for codes in the PCM? I've checked for codes with a OBD II scanner and none have come up since I replaced the MAP. Should I just replace the TPS and see if that corrects the issue?
