A-5 trans code P0701..?

Recommended Posts

New to the board..

lookin' for info on the dtc P0701..

3500 Duramax-Allison crew cab dually..

ses light comes on only when towing in high gear..and only when going up

hills ..couldn't read the code with a cheap scanner or a snap-on scanner..

had a buddy with auto tap software who could read the code..

am I looking at high gear clutch slip or tcc slip..?

any info would be greatly appreciated..

thanks ahead!
