Marlin Crawler has been rebuilding Toyota transmissions for over 30 years. Through our vast driving experience and mechanical expertise, we have developed advanced Heavy Duty rebuilding techniques and unique internal upgrades that increase the transmission's durability, longevity, and performance.

Our rebuilt transmissions far exceed Toyota OEM standards. Because of this, we rebuild high quality transmissions for many Toyota Dealerships, countless Competition Rock Crawling Buggies, Baja 1000, Desert Race classes 1450 & 7s, Off-Road Stadium Race Trucks, and Drag Supra Racing Teams. The prestige of our transmissions has been featured at numerous car shows including multiple entries to the Specialty Equipment Market Association (SEMA) Show and the Canadian Off Road Expo.

W56-A, -B, C? D...?

These letters are not used by Toyota, so where did they come from? Back in the mid 90s Marlin realized he needed a better way to distinguish between the many different W56 transmissions Toyota used from 1985-95.

After having compiled the world's first and only RF1A Transfer Case Bible, Marlin created these now highly popular letter designations for the W56 transmission. The rest as they say is history!
