WOT = no Overdrive anymore?

WOT = no Overdrive anymore?
1992 Camaro Z28 with a 7004r (with Transgo shift-kit).
Recently I discovered that it doesn't want to shift to (I believe is overdrive) when I floor it; just goes into the redline).
I can shift into each gear without any problems
- Park = no problems
- Reverse = No problems
- DRIVE = No Problems
- Overdrive (D) = No Problems
- 2nd Gear = No Problems
- 1st Gear = No problems
They all appear to work fine. If I put it into DRIVE and then shift into (D), it successfully lowers the RPM's so that seems to work.
HOWEVER if I WOT, the tach just goes into the red and doesn't shift out 1 last time to decrease the RPM's like it used to.
WHAT can this be? A clutch? Pad? Throttle Linkage? or could this mean my Valve Body is GONE and needs replacing? (which I assume means I have to buy another shiftkit?)
The transmission was rebuilt twice already:
- Shift Kit
- Gasket and Seal set
- 9 Friction plates replaced (Kevlar)
- 9 Steal clutch plates were replaced
- Band H/D replaced
- Bushings replaced
- TV Valve replaced
- And a re-manufactured torque converter replaced
This was all done in 2006 (8 years ago)
What type of $$ are we looking at and what do you think is the problem?
Thanks

Re: WOT = no Overdrive anymore?
Basically I FLOOR IT.. It jets forward but it goes INTO the red before it shifts one last time. I have a shift kit so I can FEEL that last shift, plus you can see when the tach jumps back.
Before I BELIEVE it was around 4,500-5,000 when it had it's last shift once FLOORED the gas pedal. Now it's all the way into 7,000 for a few seconds before it finally shifts one last time.
The car is at the dealer and the transmission technition took the car out on the freeway with me in the passenger seat. And he says it's shifting normally except for the last and SUSPECTS that it might just be the TACH NEEDLE incorrect and so it looks like it's in the red..
I donno I don't see that being it.. But perhaps because it goes into the 7,000 fairly quickly..
Before this "problem" I woud floor it and it was get a shift early on that would just SHOVE you into the seat.. Now it GAINS SPEED but without that SHOVE on that shift (Shift 2 or 3?) not sure how to tell..
