Jims50chrysler Posted April 1, 2008 Report Share Posted April 1, 2008 Ok This is kinda backwards but......I just finished my rewire for 6 volt then decided I should have rewired for 12 volt, I know, not a bid deal the 6 volt wiring will suit the 12 volt system so now my question is, What will be required for my Fluid drive transmission, would a volt drop work here? do I need to replace all the electric components? Where is the best place to get the components if I need them? All your thoughts and suggestions for the conversion would be helpfull. Thanks Jim Quote Link to comment Share on other sites More sharing options...
windsor8 Posted April 1, 2008 Report Share Posted April 1, 2008 I've questioned the same thing about 12 volts on my 41 Chrysler's Fluid Drive. Maybe some one can give us an answer. Quote Link to comment Share on other sites More sharing options...
bob_amos Posted April 1, 2008 Report Share Posted April 1, 2008 We did a 53 Chrysler a few years ago with the electrically activated trans. We actually inserted a voltage drop in the system where the voltage was fed to the servo, switches and governor harness, as I recall. (If I had the wiring diagram in front of me I could suggest the point of insertion a bit better.) The 53 has been out for about 3 or 4 years and still works fine.

paulbone Posted April 3, 2008 Report Share Posted April 3, 2008 I converted my 48 Coupe with Fluid Drive last winter. I didn't touch the transmission, and she runs just fine. I get much better starting now, especially as the engine was quite tight after I ddi the rebuild. Quote Link to comment Share on other sites More sharing options...
Beto0311 Posted November 25, 2017 Report Share Posted November 25, 2017 Did anyone actually draw out a schematic diagram of how to wire up these fluid drive tranny? Im still driving the fluid drive in my 51 coronet... please excuse me for reviving an old thread... any pictures/schematic/parts list would be greatly appreciated. Thank you for your time gentleman Quote Link to comment Share on other sites More sharing options...
Tubman Posted November 25, 2017 Report Share Posted November 25, 2017 If you have an actual Fluid Drive (like "paulbone" above), I don't think you have to do anything. However, if you have the semi-automatic transmission that was called "Gyro-Matic", there is some work to be done. Unfortunately, I don't know what it is. Your car should have one of those two names on it that should tell you what you have. Quote Link to comment Share on other sites More sharing options...

Beto0311 Posted November 25, 2017 Report Share Posted November 25, 2017 Wired up the car to 12v, but when i came across the transmission wiring, it overwhelmed me, so i left it for the last task of wiring. Haven't been able to get it wired correctly to shift normally. Quote Link to comment Share on other sites More sharing options...
Tubman Posted November 25, 2017 Report Share Posted November 25, 2017 I would think someone here knows. Have you tried searching for "Gyro-matic" or "Gyro Matic"? The title of your thread is a little misleading when it references "Fluid Drive". If you don't get any response here, you might try the H.A.M.B. There was a discussion about these transmissions going on over there a couple of days ago. Quote Link to comment Share on other sites More sharing options...
Dodgeb4ya Posted November 25, 2017 Report Share Posted November 25, 2017 1949-1950 Chrysler's name for the transmission is called "Presto-Matic" Dodge called this same transmission Gyro-Matic. Quote Link to comment Share on other sites More sharing options...
Niel Hoback Posted November 25, 2017 Report Share Posted November 25, 2017 I believe my DeSoto said "TipToeShift". Quote Link to comment Share on other sites More sharing options...
Dodgeb4ya Posted November 25, 2017 Report Share Posted November 25, 2017 Tip-Toe is the name for 1946-48 DeSoto There are several more manes for these vacuum and hydraulically operated transmissions for the 1941-53 Mopar transmissions.
