My 2670 comes to a dead stop when your going down the road and you push in on the clutch/inching pedal. I left tire marks on the asphalt when I came to a stop sign and pushed in on the clutch. Why would it be doing that?

If it does this only when depressing the pedal all the way in 2nd and 3rd powershift not in 1st powershift, especially with cold oil, C-3 retard is not letting the oil out of C-3 clutch pack quick enough. Back out the screw 1/4 turn at a time and try it. This screw adjusts the shift timing from 2nd down to 1st. All of the shift timing changes with oil temperature. Any more questions, ask them.

You have to pull back the floor mat, remove the plate on the cab floor. (5 screws) Usually there is a fiberglass insulting mat to lift up and you will see the powershift control valve. It is about 12 inches square. You will see two screws that take a 3/8 wrench with a screw driver slot. You will have to loosen the jam nut with a 7/16 wrench. The one closest to the right rear corner is C-3. The other one toward the front is C-2. You will turn out C-3 to solve the problem.
