I have an 05' 2500 4x4. 80% of the time transmission shifts fine, but sometimes when coming to a stop the transmission only shifts down to 2nd gear. It is not downshifting to 1st. Even manually shifting it to 1st does not work. The only way to get it to go back into 1st is to put it in park shut off the motor restart and put back in drive. Then it shifts correctly.:banghead: I have taken it to the Dodge dealership and they say no problems. Sounds like a computer problem? But dealer says its not flashing any codes. Any clues? I'm stumped.
