4l60E binding in 1st gear question.I have a 4l60E that is what I would describe as binding in 1st gear, manual low or drive range.What I mean by binding is it takes excessive pedal to move forward and the rear tires will actually lock up/slide when letting off the pedal.As soon as it shifts to 2nd, it will immediately unbind, feels like a rubber band snapping..reverse, 2nd, 3rd, and OD is all good.Band clearance is within specifications.*Any ideas on this one? I dont know history on transmission other than it was rebuilt by a well known shop years ago and has been sitting. I finished the project car it was in and found this problem. So far I have switched valve body with known good valve body of the same year 94. Also removed transmission and checked everything sprag, clutches. Exc. Ive built over 20 4l60e's never had a problem like this. And yes the trans is getting power and ground signals. Thanks in advanced for the help.
