Traxxas 3695X Pro-Built Magnum 272 Transmission

The Traxxas 3695X is a Pro-Built Magnum 272 transmission that arrives ready to install, precisely assembled to Traxxas' exacting standards. Rather than sourcing a housing, gears, shafts, and bearings separately and building the unit yourself, this comes complete and ready to drop in.

That matters more than it first appears. A transmission rebuild is one of the more involved jobs on an RC vehicle, with shimming, gear mesh, and bearing seating all affecting how the finished unit runs and how long it lasts. Getting any of it slightly wrong produces noise, drag, or premature wear. Pro-Built components remove that risk entirely: the assembly work is already done correctly at the factory.

Pro-Built parts save time and make it easy to restore like-new performance with factory-fresh components, ensuring the model delivers the performance, durability, and fun it had when new. For a vehicle with a worn or damaged gearbox, this is the fastest route back to running condition.

The package includes 76T, 83T, and 86T 48-pitch spur gears, giving three gearing options out of the box so the final drive ratio can be matched to the vehicle and running conditions without buying gears separately. Genuine Traxxas part.
