Quick question, any ideas how it might be possible to arrange an external hydraulic pressure feed to an automatic gearbox such as a vauxhall cavalier one for example??
I have been toying with the idea of removing the torque convertor from one and altering it to drive through a conventional clutch, but this then also removes the hydraulic pump, which is obviously required for the shift hydraulics.
The idea is obviously to get a hydraulic clutchless powershift box but with a normal clutch for the startline and to avoid the parasitic losses of the convertor.

and as for why you'd want to do this, seems you get the best of both worlds:

Basically, you add a clutch in place of the torque converter and you're left with a planetary transmission that can be shifted without a clutch after launch. It's primary application was in drag racing where you are more concerned with upshifts during the 1/4 mile run.
