OK, sounds weird but could it be done?

This is an "out there" idea but what would happen if you removed the torque converter from an auto and replaced it with a manual clutch?

You would need to make up an input shaft that suited the auto and had a normal manual transmission input shaft at the front for the clutch plate to slide on. You would need a throwout bearing ect but nothing too hard to create.

The TC only allows slippage when revs are low. and engages drive at a preditermined level of revs rise.

This would allow you to decide at what revs the car started to move forward, then you could let the auto do the changing or use a "tiptronic" type device to shift gears.

Think about full power up and down shifts without lifting off the throttle.

The TC has little to do with pumping oil for the trans so the trans should still operate.

This has come up as I want to run a manual in my next project but the transmission is almost 2.5 metres behind me so a gear lever is as bit unwieldly.

This could give me the best of both worlds, as the vehicle will have a heavy rear weight bias and this would allow me to drive sensibly or drop the clutch and see what happens.

At this stage I'm looking at using a 1UZ but I can go up to a Chev 454 within the RTA rules in my State so things are still a bit open.
 
Hmmm i suspect not? The TC absorbs a lot of shock on shifts so even if possible to set up it may not last long?
 
In the middle of the night I figured out the TC drives the pump and if the TC was replaced by a clutch the pump would only work when the clutch is released.

You could get around it by driving the pump with a cage around the clutch and use a Howe concentric throwout bearing but it's starting to sound bizzar and impractical.

Maybe I should have thought it through a bit more.

Not sure the ZF would take much more power than the A340 and I was actually wanting a auto transaxle but finding one is harder than it looks.
 
I have seen it done somewhere but cant remember. The gearbox was fully built to suit though so wouldn't be cheep.

Whats wrong with using cables to connect a shifter to a manual. There are plenty of front wheel drives that use cables between the shifter and gearbox. I would have thought a transaxle would be set up like this anyway.
