I lost 3rd and 4th gear in my truck still had reverse ,1fst and 2nd gears. I got a used tranny and put it in and still no 3rd or 4th gear. My original tranny it would go from 2nd to nothing like it was in neutral . This tranny does not slip out to a neutral feeling please help

 

Post your vehicle info please. year/mode/engine and tranny if you know it.

 

1997 silverado 5.7 2wd 4l60e tranny

 

That's how it goes with used transmissions. It's a craps shoot.
