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
