Do you mind using a toggle switch to turn on the over drive and lock up? If you don't mind, use a 47rh. For $4-$5k you should be able to get a goerend, Firepunk, or Pro Street Diesel Trans, with a billet triple disc converter, and it'll take a lot. Just for reference, a 47re core with TC is only around $350. A 47rh with TC, expect to pay $500 and up if it works. I like the 47rh because you don't need a controller and you don't have to buy any aftermarket adapters. You can get a diesel A518 found in 91.5-93 dodge cummins trucks, and then get a 46rh gas trans, and have a shop build you a 47rh from the 2 other transmissions. The only big difference will be the 518 cases don't have the reinforcing ribs for the servo on the side. I've seen them brake there on trucks that were all jacked up and had shift kits int he transmissions. Dave Goerend told me he's seen theses type of 518/47rh transmissions break in that area a lot but they were probably being abused heavily.

Here's a thread explaining a 518 being turned into a 47rh.
