Okay, I just can't pull the trigger until I explore both options. So I'm still looking for someone that is running a 4r70w with a baumman controller. Really want to see how smooth they are under normal driving circumstances, and then how well they shift when hauling ass. I've never had any experience with a performance automatic.

I swapped in a 4R70W out of a 94 F150 into my Mark VII several years ago.
I have the Baumanator, which is now obsolete, The next generation is the Optishift. If the Optishift is indeed superior to the Baumanator, the holy sh$t.
You have complete control over shift RPM, shift firmness and when the converter locks up. Shift firmness is a function of TPS, so you can program it to shift comfortably when you're putzing around, but the deeper into the throttle, the harder the shift.
You can taylor the WOT shift RPM for each gear.
Not only can you lock up the converter when you want...in any gear you want...but you can even program the time differential between the tranny dropping into O/D and the converter locking.
I'm telling you a programmable 4R is second only to boost or big cubes for the fun factor.
There are still thousands of 4R70Ws behind the up to 99 V-6 Mustang and some of the later F-150s that have the Windsor bell house pattern.
The big drawback is the shifter situation. For you Mustang guys the easy fix is swapping in a 94 up shifter or an aftermarket.
The 2nd drawback is the price...but it's worth it.Originally posted by danielhv View PostOkay, I just can't pull the trigger until I explore both options.
