## Description

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: Very high quality. - Very good quality product. Fit with absolutely no issues. Would highly recommend opening the unit to fill with more grease. Also it it worth mentioning that if you intend to use the included metal spur gear that it will also require grease as the motor gear is metal. I ran it for a minute after installing and found that it was very loud before adding grease.

## 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

### ⭐⭐⭐⭐⭐ Very high quality.

Very good quality product. Fit with absolutely no issues. Would highly recommend opening the unit to fill with more grease. Also it it worth mentioning that if you intend to use the included metal spur gear that it will also require grease as the motor gear is metal. I ran it for a minute after installing and found that it was very loud before adding grease.

### ⭐⭐⭐⭐ Shipped dry! Make sure to get grease!
*by K***R on April 25, 2023*

As other reviews stated, assembly ships dry. The screws holding it together were loose, thankfully I was pulling it apart anyways. It has some nice weight to it. It is louder than stock but that's just how metal gears sound. Only ran it twice now and it holds up decent. I suspect low gear is lower than stock as it's slower than stock, however it remains to be seen if has more torque. Over all would definitely recommend. I needed new transfer case gears and a new tail housing. This was the best bang for my buck so far.
