Unit works, but it EXTEMELY loud. I did open it up and install grease as the unit doesn't come greased. I'd rather put new bearings in a stock traxxas transmission than run the aluminum one. Do not recommend.

This is a great transmission. Everything on or in this is metal including the spur gear and clutch piece that changes the transmission from 1st to 2nd gear. It is really smooth. Smoother than the stock transmission from Traxxas.

Very well built the shifter fork on the internals is made of aluminum instead of plastic like the Traxxas brand. Also has a metal spur gear. Make sure to crack the case open and put some Grease on those gears and on the rear cover for front and rear output shaft they just have factory oil from when the parts were made

I was weary about this product but its fantastic. The shift fork is all metal unlike the traxxas one. Machine quality was fantastic. Been running it hard for about 2 months now and ive been super happy with it. Just be sure to open it up and pack it with marine grease as it comes assembled with zero grease inside. The unit fit right in my TRX4 with no issues whatsoever. Shifts smoother then the factory traxxas transmission as well.
