I only know TCI builds this

Well I have been having fun with the TCI kit, ended up chatting to their only support crew and found out that it is an obsolete kit. So what is out there is all there is.
So carried on looking and found that Quick Time now make them ( Few ) .
Only thing now is it says "The Quick Time Automatic Bump Start Kit for Powerglide Transmission is used on circle track vehicles not using an electric starter. This hydraulic actuator bolts on in place of the servo cover allowing you to apply the clutch band to push or bump start the engine on a direct drive Powerglide automatic transmission."
SO, does that mean it won't work at all with a torque convertor. OR how much difference would there be in running the box as a direct drive, like the circle guys do???
Damm, thought this was getting easier, and now I have more questions. Sigh Sorry.
