well i have had so many problems with my 4l60e i was looking at putting a TH400 in.. well i drive the car a lot and i was searching and saw they have a overdrive unit that you can put on the tailshaft, they look pretty cool.. i was wondering if anyone else has one, and have you had any problems with it..

A 4L80E would be a lot cheaper as well and you'd go faster. A TH400 and a Gear Vendors Overdrive would consume as much parasitic loss as two transmissions - you'd lose a huge amount of power going that route. That and a GVO is very expensive by itself. The 4L80E would be more efficient, a lot cheaper and just as strong.
