4l60E no overdrive...rebuild. still same issue
Ok I got this vehicle only driving n 1 and 2. Shifts to 3 or d would result n more less neutral.
I got this car for cheap and was looking to fix and resell. I pulled the trans expectiong to find either fried clutches or a bad Forward sprag.
I looked the forward sprag over and it was good and cound all the clutches to be burnt and wore to nothing. I bought all new clutches and steels and replaced just to move it down the road.
After replacing first starting the car I stuck it n drive and it made a good solid kick n and then I went back to reverse and then back to drive. tapped the throttle all was good.
After pulling the car out I put it n drive and nothing....I gave it a little gas and it lunged. So I popped the hood checked fluid and there's plenty of fluid. I I tried 1 and 2...and they are solid and drive great. But 3 or d sometime n gear seem to be there...other times not.
While playing with it I did notice if I put it n netural and rev the engine it does creep forward.
anyone have any idea's?
Thanks Jeremy

I'm not sure if this is still true but You used to be able to buy a complete rebuild kit 4 a 700/r-4 4 $60 . A 4-l60 is the same as a 700 except the case is different . Have You considered the shift solenoids ? They do fry once in a while .

As chrisfrost suggests, I would start by replacing the shift solenoids as they can develop electrical problems or get clogged and act intermittently.
Having the car creep a bit with trans in Neutral and engine revved is normal - there is enough friction in the input drum clutches to cause that.
As chevybayboy says, it is critical to know whether the check-engine-light is on.
