Quick question, I currently have a 4R70W tranny in my car. Would I need to change the ecu in order to run a 4R75W which came in the automatic Mach 1's?

short answer is no your ecu will work just fine with it. long answer is that its actually the exact same trans with stronger internals for a higher torque capacity.

Thanks bro. As soon as I find a tranny I'll let you know so we can set something up, if I don't find one I might have to rebuild my current one though.
