C6 Lock up torque converter.

[XOLATEM]

By the time you were done you would have a different model of transmission, if I know Ford model number stuff well enough it would be called the "C-6E"

Maybe...back in the day before that screwball Brit that the Ford family put in charge 'fixed' it so we have to have a lift and AC machine to work on our stuff...but that is another story...

Let's say that Ford did decide to add a lockup to the C-6...well...they took the C-4 and added a mechanical lock-up convertor and changed the valve body to accommodate the resultant harsher shifts...they called it a C-5....

It is quite possible that a lockup C-6 would have been a....(Gasp)...C-7..!!!

Think of the possibilities..? Then again..it could have very well been a C-6E !

Fortunately...I believe the E4OD was already in the works...so...they didn't need to do anything of the sort....

The stuff I come up with sometimes....you would think that I had better things to do..?
