auto transmission for a 1966

[David Johnson]

I think a 700r4 will work, but you will have some minor things to overcome. One is, you will need a vacuum over electric switch. Summit has them or you can rob one off of a salvage truck. Second, there is a brake switch that disengages the lock-up or something when you hit the brakes. That too can be had from a salvage yard. Also, the 700r4 has a different type of kickdown cable. hope that helps.
