Have a growl in the tranny in my 46 burb and was wondering if there is a more modern tranny (with synronizers) that will adapt or bolt right up to make it drive better. Its a 4 speed on the floor

You can use a '49- 54 SM-420, but you may have to change the bellhousing to accept the larger pilot gear retainer. Alternately you could have your bellhousing bored to fit the SM-420.

You well have to change the bell housing to use the SM-420, but that's the easy part your driveshaft and torque tube is 1 9/16 inches too long. Good Luck

It would probably be alot easier to use a 1941-47 pickup or suburban 3-speed. It will bolt in without any modifications. The 2nd and 3rd speed gears are sycronized

Another option would be to put in a 1946 3 speed on the floor. They have syncro in 2nd and high.
