#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.
When you couple each of the characteristics of this transmission; a short length, light weight, wicked-low first gear, and superior strength, it truly is the perfect combination for nearly everyone looking to put a manual transmission into their rig. It will fit perfectly in the shortest of rigs, and it can also handle the stresses of a very heavy 4-wheel drive truck that has big-block power within.
Supplies of this transmission are diminishing though, and if you're considering this manual gearbox for a swap, you'd better start looking fast.

• <LI itxtvisited="1">What we like: A super-heavy-duty transmission capable of handling insane amounts of torque. Wicked low first gear. Available PTO (power take off) port. Relatively small package. <LI itxtvisited="1">What we don't like: non-helically cut first and reverse gears made it difficult to shift from 1-to-2, and from R-to-1. <LI itxtvisited="1">What it came in / When it was available: The SM420 was available from 1947 to 1967, but a military version was available up through the early 1980's. These transmissions could be found in GM trucks, busses, heavy equipment and various military applications. <LI itxtvisited="1">Identification: The cast iron top-cover uses 8-bolts to retain it, in a rounded-off "house" shape. There's also a large bulge on the passenger side to make room for the reverse idler gear. It measures 10.4" in length and 17" in height. <LI itxtvisited="1">Quick Specs:
