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

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

Good 2 speed

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.

Good upgrade.. couple nicks in outside housing like it fell. Laelte shipping.

Fits perfect and did the job without any fuss. You can add a shift servo if you want to shift between high and low gear. Mine arrived in high 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.

Not sure if I got a bad unit or what happened but I had it on the stand just doing a bit of testing after installation and after about a minute it locked up, didn't even get a chance to actually use it andi can't seem to get a message to the seller about a replacement, might want to avoid this one

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.

Just make sure you check the spur gear for tightness. (its the metal spur gear thats loud not the transmission)

Perfect set up same as stock but all metal. Take apart and grease with synthetic

Quality gear box assembly. The only thing I didn’t like was that the internals were dry (good thing I like to take my RC things apart to inspect them before I use them).

Loved it exactly what it is make sure as I did pull it apart and grease it it uses torx head screws T8

Trans works good I recommend greasing before use. The front output shaft was not drilled straight for the grub pin so my front shaf wobbles a bit. Swapped in my stock front output and no issues.
