does anyone know about the 6L80 that came in the M1151A1? I seem to have an issue with the shifting = meaning that it seems to need some accelerator pedal release each time I need a higher gear. The fluid is fine and red. I serviced it with a new filter and re=usable gasket. One note is that the gauge panel is missing and I was wondering if the electronic speedo had any input into the transmission control box. I was thinking that it had no idea where the pedal or speed was. It seems to be the same wether I am in overdrive or any other position. It is quiet similar to a new trans etc
