Traxxas TRX-4M 2-Speed Transmission

Transmission Overview:

Traxxas® TRX-4M™ Two Speed Transmission. This transmission is designed to enhance the crawling capabilities of the TRX-4M™ by offering a selectable high and low gear option. This transmission provides a low gear for increased rock-crawling torque and a standard high gear ratio for general driving, making it versatile for various terrains. It comes fully assembled with a Titan® 180 motor and includes a mounting bracket for easy installation. The transmission features a manual shifting lever that allows users to choose between low gear (32.7:1) and high gear (9.9:1) settings, providing flexibility based on the driving conditions. This setup integrates seamlessly with the vehicle’s stock components, including portal axles, making it a valuable upgrade for enhancing the performance of the TRX-4M.

Matt H Verified Owner Tuesday, May 20 2025 (4 months ago) Traxxas TRX-4M 2-Speed Transmission Add this to my TRX-4MT along with the upgraded motor and ESC. install was easy. the lever can be hard to move at times if you don’t take the Body off. Can’t wait to get the shifting servo installed. Shawn Lesko Verified Owner Monday, Apr 21 2025 (5 months ago) Traxxas TRX-4M 2-Speed Transmission If you don’t want to buy two TRX4Ms – one for crawling and one for bashing – enter this two speed. For those serious about crawling, beware, it raises the CG. For those that bash and want to occasionally crawl, I question its durability. In my own bashing of a TRX4M Bronco(modified as follows: no brass, Traxxas brushless system, metal diff gears, metal driveshafts), I have already stripped internal transmission gears. View all reviews
