Mopar automatic overdrive for RB engines?

[toolmanmike]

I had a friend ask the question and I had no answer. Did Mopar produce any o/d automatics that will bolt to a RB? All the ones except the diesel Torqueflites were small block case trannys. I read a few threads about Gear Vendors or SMR units. Thanks

The only way to mate a factory OD trans to a BB is with an adapter or an Ultra Bell housing.

Yeah, for a big block your would have 2 .Both would use adapters.Silver State transmissions (G.M.) and the J.W bell like Dipstick said above. We did the J.W. with a 518 behind a 500'' stroker and allot of floor and crossmember work in a 72 B Body back in 2004. Gear Vendors may be the easiest to install.When all is said and done the cost is in excess of $4000 to do the job what ever is chosen.

Also to add, the stock 12'' converter will not fit the J.W. bell housing. I can't remember if the 11'' fits either. I'm pretty sure we had to get a 10 1/2.

Go to this website, and call them. They make an adapter to attach a 904, SB727, and 518 transmissions to a BB Mopar. There is NO transmission cutting or modification, it is a bolt on kit.
