hey Guys,
TCM is bad on my 2009 Bucket truck gmc topkick.
the original service number was 25978353 A50
the new one i got service number 24256861 is an acdelco t14 replacement
the operating systems are different and cant swap trans segments.
Can anyone help with a calibration for this truck, was trying not to have to get it towed to dealer.
thanks
kurt
