35 mph WOT power loss

Yea im pretty sure it is, its actually been shifting really well the past couple days. I was having flare up issues on the 2-3rd shift, and right now its the best its ever been since rebuilding it.

My valve body does not have the governer ground because I couldn't do it, so there isn't the manual downshift at any speed, but the transmission should do it normally by itself. Ill check it out.


What year is the transmission? It should have the part throttle kickdown unless it's an early one.
