kickdown rod dilemma - throttle not opening fully SOLVED !!!

66fyssh said

Fluid is good. I just rebuilt it during the swap. It runs like a raped ape with the Kickdown rod adjusted but the throttle won't go all the way open.

My plan is to drop the pan and increase throttle pressure at the valve body. I just wanted to see if anyone had any other ideas before I do that.

I think you're on the right track with that, but it bothers me that the transmission slips without good throttle pressure. It should not slip....that is unless something is wrong. Even with the throttle pressure linkage chunked in the ditch, if the transmission is in good shape, it WILL NOT slip. At least not right away. It will simply shift very early. If it slips, something's up.
