Review: Solid - As others stated add marine grease to the trans mine was dry. Direct fit everything worked no issues. Metal spur is alittle loud so I may switch back to plastic till that dies. Not bad at all for the price update: 2 days later let my 13 year old daughter mess around and some how she blew it up making a ticking noise try one more time if it die will go back to stock
Review: Heavy duty - Good 2 speed

## Questions & Answers

**Q: Does this come with everything the new one has to convert the sport to two speed?**
A: Yes it comes with the two speed gears pre installed and the two speed fork and shaft for the shift servo but you will need to buy a servo and mount to operate it. 
beware: the metal spur gear is very loud compared to the stock one I run the plastic gear because it cuts down on noise. Hope this is helpful.

**Q: Will this fit the trx4 sport?**
A: Yes,but make sure grease all gears. I found it a little dry

**Q: Does this fit the TRX4 k 10 high trail?**
A: Absolutely and it's a fantastic transmission less play and less noise than stock I believe they are even hardened metal gears not the Traxxas "metal"

**Q: Does this fit the T-maxx 3.3**
A: Yes it fit

Good 2 speed

### ⭐⭐⭐⭐ Nice metal motor…
*by D***H on March 7, 2023*

I have the sport edition and I had to do a lot to lock the gear so I didn’t have to mess with it coming unlocked but it was simple just copied everything from the stock plastic motor but it is a little loud but I don’t care and I’m starting to hear a clicking sound after about 4-6 hours of use truck still runs fine . Alright price for this metal motor.
