Just pulled the pan off the truck to investigate the no reverse problem. Found the reverse servo was broken and the lip seal was pushed down.. See pic. Seems to me that might be my problem. Truck is a 92 W150 and it lost reverse just all of a sudden. All forward gears seem to be fine. What do you guys think?

That's your problem and not all that unusual.

Where can i get a replacement? Do they make an updated version so that might not happen again? Here is a better shot of the servo.

Check the transmission/differential section of the swap meet forum for a billet piston, spring and retainer.

You can check local transmission shops too. I'm in the middle of building my 518. All of my parts came from Transtar.

sonnax makes upgraded replacement parts...although they are nothing like the billet ones...but nice to see alternatives to the stock parts
