skip1954 Posted January 5, 2012 Share Posted January 5, 2012 I wanted to ask if anyone would have any images of the m4 transmission and fluid drive in a 1941 Chrysler. All the components were removed from the vacuum to carb to the switches of the transmission, I have recovered most of the parts required to fix the problem. My major problem is that looking at the manuals and schematics, there is not a good picture of the exact locations for the shifting components, I think I am missing a mounting bracket for the switch to the carb and/or throttle, if I could see a picture of existing car with this set up I know I could mount all the components in the right way and the Trans will work as it should. Any information that you have would really help. You just don't find 1941 Chrysler Royals in Southern California Link to comment Share on other sites More sharing options...
skip1954 Posted January 6, 2012 Author Share Posted January 6, 2012 (edited) Please help!!!! Isn't there someone out there with a 1941 Chrysler willing to take detailed pictures of their electrical controls/componets to the fluid drive, so I may get my 1941 on the road. Any help would be good, Thanks Edited January 9, 2012 by skip1954 (see edit history) Link to comment Share on other sites More sharing options...
Guest De Soto Frank Posted January 6, 2012 Share Posted January 6, 2012 Skip,Can't offer you anything in the way of pictures of installations on real MoPars, but, on the '46-'48 versions at least, there was a special carburetor for the semi-automatic cars that had a built-in kick-down switch - a little plunger on the one side, and a terminal lug or female-bullet on the opposite side. There were two different versions of the dashpot that retarded throttle closing: one with a spring-loaded screw in top of the dashpot (actually the top casting of hte carb), the other version has an electromagnet with one or two femal bullet terminals into a little cover that bolts to the top of the carb.There should be a relay that mounts on the firewall, above the steering column, but below (or beside ) the voltage regulator.As for brackets, I think there is a bracket to mount the vacuum shifting servo to the transmission, and a bracket on the other side to secure the outer conduit of the lock-out cable.I will check the factory parts book I have for my '41 De Soto ( which used the same smei-automatic transmission set-up), and if there are any good detail photos, I will see about getting them scanned and sent your way.These are kind of rare, the M-4 being used only in the 1941 and '42 models.The shop manual should at least have a clear schematic for wiring the system.

MarkV Posted January 7, 2012 Share Posted January 7, 2012 I have a '41 Dodge coupe with the standard transmission, I however, do have a fluid drive in pieces if you needed extra parts! And I live in Southern CA! Link to comment Share on other sites More sharing options...
skip1954 Posted February 28, 2012 Author Share Posted February 28, 2012 I wanted to thank all of you for the help with the fluid drive, I am back on the road. I found a place in Torrence, California that was able to do the work. I really wanted to thank Desoto Frank and Rusty O'Toole, thanks for putting up with my questions, it's all down hill from here.My next question is exactly which oil to use (30W non-detergent) ?What is the final conclusion on the tires (Bias- Radial) ?

Rusty_OToole Posted February 29, 2012 Share Posted February 29, 2012 OIl for what? If you mean the engine do not use 30 non detergent. Use a good multiweight detergent oil. Rotella 15W40 is a favorite, or any good brand 10W30.Detergent oils were introduced in 1947, multigrade in 1951. They were the default choice at all garages and dealerships from the fifties on. I worked in a garage in the sixties, nobody used non detergent single weight oil except cheapskates driving worn out oil burning clunkers.Don't listen to the bullshit put out by self styled experts.

Guest fustydad Posted March 19, 2012 Share Posted March 19, 2012 I have a 41 chrysler royal with the original motor and trans. Do you need exterior pics? Link to comment Share on other sites More sharing options...
skip1954 Posted March 20, 2012 Author Share Posted March 20, 2012 Fustydad:Thanks, I have worked out all the problems, I was having with the transmission. Now I am completing the interior restoration. Now I am redoing my front end suspension, the only part I would like to have is the lower control arms, in the near future.Skip Link to comment Share on other sites More sharing options...
