Looking for recommendations transmission builder in Denver for 4R70W Hi Denver, I live in Colorado Springs and can't find what I need here. What I need is a transmission builder that is comfortable building transmissions that go behind high horsepower motors. If you know of someone, please let me know.
Specifically, I am looking for someone to build me a 4r70w transmission that will go behind a supercharged 351W with output to the flywheel of \~420 hp/460 tq.
