Guest lmadsen Posted July 1, 2014 Share Posted July 1, 2014 I have a 1947 chrysler that has the fluid drive transmission. Lately after the transmission shifts to third gear and it won't stay it shifts back down to second. Is there an adjustment or something that needs to be cleaned that would resolve this problem. The car is not driveable under these circumstances.ThanksLarry Link to comment Share on other sites More sharing options...
AlanT Posted July 1, 2014 Share Posted July 1, 2014 It sounds like the governor isn't working right. I'm assuming you have the M4 transmission. Does it do this in both high and low ranges? Depending on how you number the gears, low range would be 1st and 2nd, high range would be 3rd and 4th. Link to comment Share on other sites More sharing options...

If it is the governor can you explain where and it is and what I can possibly do to fix the issue.Thank youLarry Link to comment Share on other sites More sharing options...
Rusty_OToole Posted July 1, 2014 Share Posted July 1, 2014 Check the oil in the trans first, top up with 10 motor oil or TDH tractor fluid, ISO22 or ISO32 grade. Also check wiring from the coil, to the carburetor, to the transmission. Sometimes they get frayed or broken. Link to comment Share on other sites More sharing options...

I found that the wire was disconnected at the carburetor. Reconnected and every thing works great. Thank you again.Larry Link to comment Share on other sites More sharing options...
