6V to 12V OD transmission

[50plywood]

I just had my transmission with overdrive redone by George Asche for my 50 Plymouth. I now want to change my car to12V negative ground. I think I have everything figured out except for the OD. Does anyone have any advice on what I need to do for it? I just don't want to mess it up.

actually there are a couple schools of thought here...and a couple ways to get it electrically/current balanced...BUT your prime concern here is what will George back up for use as certain as taxes if there should be a fault he will be called upon to make it good.  I highly recommend you sound this out with him personally.

I agree with Plymouthy, Call George Asche and get his recommendation

Sounds good. I have had it back from him for about a year and am just getting my car back together. I'll give him a call.

There are a lot of us who are running R10's on 12V cars with no changes to the transmission components.  It's a good idea to go 12V on the relays; I actually did my own electrical package using 12V stuff sourced from McMaster-Carr.

I talked to George and that's what he said also. He said I just need to change the relay and suggested a starter relay for a 70's Plymouth. I appreciate the help.

Been running mine on 12 volts for 4 years ....no issues......I used a Bosch 30 amp relay.....available everywhere.....
