Jj1981 Posted February 21, 2018 Report Share Posted February 21, 2018 Found this in an old dodge school bus on my buddy’s farm wondering if it will fit my 218 only numbers I could find c-3866 thanks Quote Link to comment Share on other sites More sharing options...
Merle Coggins Posted February 21, 2018 Report Share Posted February 21, 2018 (edited) Is there a "1" at the end of that number? C-38661 is the casting number on my spur gear (non-synchronized) 4 speed. Mine has the Fluid Drive input shaft, but I would imagine that the case is the same on the standard version.

Dozerman51 Posted February 21, 2018 Report Share Posted February 21, 2018 One quick way to tell a spur geared NS tranny from helical cut geared S tranny is to look at the location of the drain plug. A spur gear tranny will have the drain plug facing downward at an angle. The helical cut S tranny will have the drain plug parallel to the bottom of the case. 1 Quote Link to comment Share on other sites More sharing options...
dpollo Posted February 22, 2018 Report Share Posted February 22, 2018 It takes a lot of talent to drive the straight cut transmissions. If you need a transmission I would look for one from a 53 or newer light truck which is synchronized in the top 3 speeds. Big improvement !
