1st gear has a quck shift and "pops" into 2nd. Can i avoid 1st alltogether and start in 2nd without damaging trans?
SOURCE: I have a 99 GMC sierra with a 4.8L 4L60E trans and
THe 4l60 is an electronic produced shift trany, It sounds like the place to start, is to see if you can shift it manually. Starting out in first and work your way up as the vehile speed increases. I have a question for you. Did this problem occur all at once or over time? I would say most common reason is shift solinoid problem, But could be many other reasons like, sticking valve in valvebody, bent or worn linkage, improper fliud pressure to pistons, etc. with your help and imput we can probably narrow the problems solution down.
