4l60e issue I'm looking for help on my transmission issue. I have a 4.8l and 4l60e from a 2000 chev 1500 2wd swapped into a 1986 s10 blazer 2wd. The transmission will go into drive but it won't shift thru the gears automatically. Manually I can shift thru 1,2 and 3 as well as reverse. But it won't automatically shift and slips above 2000 revs when in drive. I've taken it to a transmission shop and they said the transmission itself was all clear and that I have a wiring problem. When using an older snap on code reader on the obd2 I can see the VSS and TPS reading clearly. I can also see the solenoids clicking on and off. Any ideas on how to fix this would be much appreciated.
