Hi Ben,

First of all, make darned certain that the adjustment is right on the control lever.

Then, I'd sure check that foot-n-inch to make sure it is closing along with the operation of the two capsules up in the hydraulic control (reverse the two capsules temporarily) just to be on the safe side. However, these "usually" would affect both directions.

When only one direction is a problem, you've got a 90% chance that either the feed pipe to the reverse regulator is split/leaking or the reverse check valve is leaking by.

Sounds like this is kinda sporadic and you can temporally override it by hitting the "clutch" pedal. This action kinda rules out the "split pipe" thing, the upper capsules and would more fall right in line with either a bad/leaky foot-n-inch valve or what I'm saying about the reverse check valve.

Those pressure regulators and check valves really take a beating, but like I say, if the problem is only one direction, that narrows it down to just the check valve. A pressure regulator would make 'er limpy in both directions as both sides would loose drive oil.

The check valve will run somewhere around $170 from CaseIH and can be swapped out in about 20 to 30 minutes.

Also, these trannys are tougher than you would think. Really, really have to abuse ‘em to make the things fail and if you have good drive in one direction, your troubles are minor because all she needs is just a little tuning up.

I’m just betting that you have a bad reverse check valve. If you want to go to all the trouble of making sure, reverse the two check valves. The “problem” should change to the forward direction instead of reverse.
