904 Valve Body

bobscuda67 said
The odd thing about the way it shifts is that the 2-3 shift is fine at low speeds and the 2-3 and 2-3 shift at wot is perfect. But at half throttle it has a flare on the 2-3 shift, 1-2 shift is quick as it should be.

I took the valve body out last night and started checking the kit install I did.
What I'm thinking is the cam on the TV is not pushing fast enough. I have the TV fully compressed at wot but it doesn't touch it at idle. I have a Edelbrock carb and their throttle extension. Maybe the ratio for moving the TV linkage is to slow. I have another post trying to find out the length of the Miller measuring tool used to set the cam stop.
Thanks for your help guys.

TP shouldn't cause a flare. Also there needs to be some clearance between the TP lever & the valve. It's unlikely its worn that much or not moving it fast enough. You would have to be constantly in & out of it all the time to wear it down that bad.
My 727 had a similar problem the 1st time I did it back in High School & we found it had a leaking kick-down servo. I learned alot more about trans overhauls since then.:banghead::violent1:
Do the shift valves (& all the valves) in the vavle body move freely in their bores?
It could still be a front clutch piston seal too. I know you had it done over before but it may have failed again. That's usually the most common cause of a flare. Also check the fit between the shaft & the drum & also the alignment of the feed holes. Any excessive clearance or misalignment will cause problems.
