C4 reverse weirdness - part 2

[GloNDark]

Brief background on the issue. It once was intermittant, and now seems permanent. I drop the shifter into reverse, I can hear a "click" and then movement from the trans but no reverse. Appears to have 1 thru 3 gears.

I swapped out the reverse servo piston hoping the seal was bad and a new one would solve the problem, but no dice.

So I dropped the pan. There was the typical gray sludge in the bottom, but overall the internals "look" to be in ok shape. No broken bands and what not.

However apon removing the valve body and taking the 2 halfs apart I ran into some weirdness. There is a hockey puck shaped item in there, but no check balls. Yah, no check balls. ?? I'm sure this has something to do with my problem at this point.

I then moved on and did the typical air checks on the valves. Everything checked out, and appear operational with the exception of the govenor valve. It blows air straight thru, no fast FAP sound what so ever.

I'm at a loss. Any ideas?

No I've only had my C4 for 1.5 years.
I've dropped the pan at least 5 times, never had any gray sludge.

Now is the time for the Trans-go shift kit. They have detail instructions on how the valve body goes back together. Do the valve body shift kit, and see if that solves your problem.

The grey stuff is clutch plate isn't it??

If there were no check balls. Im surprised it had reverse at all! There needs to be 3 viton balls, 1 in each bathtub and 1 in the corner of the channel plate. The bathtubs are wells for the shuttle balls and 1 is in the valve casting and the other is in the channel plate. The hockey puck is not vital for any reverse function it softens the 2nd gear shift somewhat. The ball in the corner of the channel plate is not needed either, if you omit it the trans will have a firmer 3rd gear shift. The 2 shuttle balls in the bathtubs are absolutely needed for proper function.
