Hmmm well at least the transmission is one of the better ones, rated #1 The GM / Muncie SM420.
The SM420... the crème de la crème, living proof that the greatest things can come in small packages. The SM420 is, in our opinion, the perfect off-road-worthy manual transmissions of all time. This tranny may be long in the tooth as some units are now pushing 60 years in age, but don't let a few gray hairs fool you - this transmission will soak up insanes amounts of horsepower without so much as asking for an oil change every few years. It's lightweight, short and incredibly strong. Oh yeah, did we meantion that the SM420 has the deepest, stump-pulling, granny gear ever available in an OE, retail setting? 7.02:1... now that's deep.
Made by Muncie for General Motors, the SM420 is a die-hard, work-horse transmission that was available in trucks rated from ½ ton to 2 ton. This stick shifter came with fully synchro-meshed 2nd, 3rd and 4th gears making every-day street driving bearable.
