no overdrive 4l60e
i have a flt lvl 7 tranny that i had freshened up with ne clutches a few months ago from a local. it does not shift into overdrive. a few weeks before this happened it would jump a couple hundred rpms and then one day it just quit shifting. i replaced the 4th servo. But that didnt help any. it shifts through 1-3 just fine. I have no codes popping up. and i cant figure out what to do next. could it be shift solenoids? even though it has all of the other gears? im at a loss here!!! i need my truck running! its been sitting for likr 5 months. Any help is appreciated.

Do you have stock servos? or aftermarket? With the aftermarket 4th servo it comes with a washer to help pushe on the Eclip at the top of the pin, I've seen this issue before where someone left that washer out and even though the servo was moving it couldn't push on the pin without that washer to take up excessive clearance, I'm most cases if you have 2nd gear and not 4th its a servo to pin issue, maybe the e-clip is missing, I would start by pulling the servos out and making sure everything is in place per diagram, should be an easy first place to start

washer is in there and have a brand new 4th sonnax billet and a vette servo. no seals are cut. this may be a long shot but i had a remote start put in a while back and they were telling me if it was installed wrong it can mess with my transmission. well last summer i got heated when my transmission line blew on the hiway. i punched my steering wheel a few times and shattered the bearings. i had them replaced along with another clock spring. one of the remote start wires had a diode soldered in and the shop that did it didnt put it back on. not sure if over time it could of messed with the electronics inside or something.
