No reverse gear and slippage in Drive 2nd gear.
I posted earlier about rebuild kit for 4l60e transmission in 1995 GMC Sierra 1500 automatic 4X4 5.7 litre engine. I have major slippage in reverse gear, if I rev engine to 4000 rpm range reverse will finally engage but truck shudders. I am now getting slippage in Drive when shifting to 2nd gear at about 35 - 40 mph when I stop accelerating. The truck has some shuddering when accelerating from a dead stop but this does not happen all of the time. Anyone else experience this and does it sound like a needed rebuild?
