Time to check some things on the 49 Chrysler Prestomatic M6. Don't think it's working properly. Have never ridden in or driven one that works normally to get the 'feel'. Help where you can please. Starting with a simple fluid change, recommended 10W. Found the access plate on the hump. Bottom plug to drain, top plug to fill. Confusing capacity already. Manual says semi-automatic, 3 pints. That's it?? Fluid Torque Drive is 10 1/2 qts. Is that the converter? Most say don't bother with that.
The manual, and copies of several posts here with tips, will attempt to diagnose the electrical components. The wiring diagram has 6 things, but not where they are located. An 'anti-stall' switch & 'kickdown switch' ..... carburetor? A circuit breaker/resistor 'box, which is on the fender well going to the ignition. Now there's a 'solenoid switch', a 'governor', and an 'interrupter switch'. Are these on the tranny? The attached picture shows 3 things wired in there. Which is which? I guess you can disconnect certain things to evaluate if they are working. And/or check the component itself, some have points that may need cleaning? If you know of a post with testing advice, please provide that. Any pictures of this stuff too. I'm really in the dark here, but ready to give it a try. Thanks if you can keep it simple.
