Classic Moose Posted July 4, 2015 Report Share Posted July 4, 2015 I have a 1938 Plymouth truck that i put a 4 speed crash box out of a 1948 ish dodge tk. I'm wondering if theres an upgrade to a synchromesh 4 speed that bolts to the truck bell. I'm new here in fact this is my first post and I'm still learning my way around the site. classic moose Quote Link to comment Share on other sites More sharing options...
B1B Keven Posted July 4, 2015 Report Share Posted July 4, 2015 Welcome!! Pics please. Yes, get a 4 speed from a '52 or newer truck. They are sycrhoed' in 3rd and 4th. Quote Link to comment Share on other sites More sharing options...
classiccarjack Posted September 25, 2016 Report Share Posted September 25, 2016 I picked up a 410 transmission that was in a 1951 Dodge. It's 3rd & 4th gears are synchronized. I am not sure if there is a later transmission out their that will fit and had the parking brake on the rear. I am putting this transmission in my 1937 Dodge ME 32. My PT57 will start out with the fully synchronized 3 speed. I know where to pick up a three speed out of a 1940 Dodge Truck. You will need to use the bell housing out of the 1940 to make it work. The Three Speeds and 4 speeds use different bell housings. Quote Link to comment Share on other sites More sharing options...
