Has anyone installed a "fluid pump repair sleeve" to prevent the torque converter from draining back into the transmission?

I think it's the TF-2 that has an anti drain back feature. Same dead cellsIf you don't have a shift kit installed in the valve body, you might want to consider this. As good as an old memory serves me, I believe that the TRANSGO kit SKTFSC (its a small improver kit) covered that problem, along with improving shift quality. Again, the old memory cells seem to recall that TRANSGO'S TF-2 & TF-3(full manual kit) also covered that problem. Just something you might want to check out.
I'm no expert by any means but thanks for the kudos. I spent almost 30 years in the transmission parts supply business, selling converters (we built in house), parts and transmission tools. I called on probably 300-400 transmission shops in my territory and had the good fortune to meet a lot of knowledgeable transmission builders. Thanks to what these builders told me over the years, I kept one very important bit of advise from them:Nothing like a “pro” in any line of work!
Sounds like good advice to me.![]()

Found out the repair SPEDI-SLEEVE goes on the "torque converter" hub and NOT the pump. There may be a special bushing out there that takes care of 'drain back' but I'm NOT sure.
I did NOT have this 'drain back' with the first torque converter "TCI" sold me with the Street Fighter 727. The original one they sold me leaked at the weld after very few miles on it. Now, this one causes DRAIN BACK into the transmission. I'm banking it is the VALVE BODY causing the drain back.
At the recommendation of AN EXPERT on this site, I left the car in FIRST gear for a few days and the fluid DID NOT 'blow out' as usual. Problem is that it worked only once. I now have it in FIRST gear again and will start it up tomorrow and see if it leaks during initial start. It usually blows out approx. 2 oz. of fluid upon a cold start. Once the T/C fills up and the engine warms up, no issues for the rest of the day.
After the car is parked for over a day, the transmission overfills from the fluid draining back from the torque converter causing the fluid to escape out of the vent hole during initial cold start. No problems once the transmission fills the torque converter again. ONLY occurs after the car is parked for long periods of time.
The cause could be a worn torque converter hub or the pump bushing. This repair requires the removal of the transmission.
Another cause could be the valve body not functioning properly.
I dread having to take out the transmission again, so, I will work on the VALVE BODY first. I have a feeling that the problem lies in the valve body.
I ordered the SAME shift kit that "TCI" installed in the transmission to make it a MANUAL/AUTOMATIC. I also ordered a PRESSURE REGULATOR VALVE from a different vendor. This new valve is an UPGRADE which makes the transmission react faster to the fluid pressure. My goal is to inspect the valve body and install the new shift kit and hopefully take care of the problem.
I have NEVER worked on a transmission before and I'm really looking forward to the challenge.
ONLY TIME WILL TELL...............
