2006 Chevrolet Silverado 3500 LT 6.6L 1-2 & 2-3 Shift
Posted to GM Transmission on 1/4/2011 4 Replies

This is an Allison 6 speed tranmission that has an intermittant harsh shift between the 1-2 shift and 3-4 shift. The rest of the time it shifts very well. The fast learn procedure made no difference. What pressures should I be looking for on the Tech 2 scanner...
