Ok so I'm thinking of building my '01 SCrew and I was wondering if I would be able to do a manual conversion, and if so what is the best performance tranny out there for the 5.4l in a manual. If I can't go to a manual what is te best performance automatic. Oh yeah i should mension that it needs to be able to handle ~750-900 hp. I plan on doing a 5.7-5.8L stroker from ModMax, with heads and cams, and also upgrading from an intercooled procharger p-1sc to an intercooled D-1sc at ~20 psi. thanks for your help

id say stick with a built auto..

 

yeah that's what im thinking now cuz the performance manuals are really expensive and yeah the auto is stronger stock anyway. thanks for your input.

You may have a hard time getting a 4R70W built to handle that much power.

 

Maybe and maybe not. Depends on who he talks to

That is a lot of power though and it would have to be done up right. Darn few could do it. But again, you have to talk to the right people.

the 4R100 could be built to handle that power more easily than the 4R70W. but it is possible to build the 4R70W enough to handle that power.

 

It has been done a time or couple dozen or so.
