RCLIONSCNC Aluminum Metal Transmission Case Gearbox with Steel Gear for TRX4 T4 1/10th RC Crawler Car

Received it quickly. Opened it up and added grease. There was a small amount but I wanted more. Looks solid and if you add the prices for the stock gears alone, it is more than this. Haven't run it yet as I am waiting on some parts, but looks well made and fits perfect.

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.

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.

Verry verry loud when driving even after i took it apart and greased it intirley

Nice upgrade to stock. Same exact item as this.Benedict Harry CNC Aluminum Speed Transmission Case Gearbox for 1/10 RC Crawler TRX-4Ask me how I know. 😆It does come dry. Don't be shy with the grease. Runs smooth in both high and low gear.

This trans is awesome I love that the 2 speed gears are all in there. It's worth the money just because of that. I replaced my trx-4 sport trans with this and it is great. I also choose this over a 2 speed kit because I hate Traxxas servo's, and I wanted to use a mini savox as the gear shift. To conclude this trans is very strong and I like the aluminum case.

Very smooth and works great. Only complaint it's very loud

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
