Re: overdrive trans
I can usually find used 4L80Es for around $500-$800. I use the Baumann Optishift TCU for around $500. I've never been able to make a 700R4 live behind my Pontiacs, and my racing transmission builder, Mike Stewart of Mike's Transmission - http://mikestransmission.com/, will not build one for my hot rods because they will not last with the torque I make...but, he has built me TH400s that handle my 1500+ ft-lb blown Pontiacs. The 4L80E is basically a TH400 with OD...keep in mind, it's not the horsepower that kills the trans, it'll be the torque.
