GLOBACTAluminum Transmission Gearbox with Stainless Steel Gear Set Low Range 40.3:1 Reduction Ratio Transmission Gear Set for 1/18 TRX4M Upgrade Parts (Black Red)

Very nicely made, came with everything you need to do a complete bolt in swap. Bought for a color scheme build and even though the color red on transmission is off a little from desired red it still looks, works amazing. 10/10 i would buy again in a heartbeat.

Good quality no meshing issues like other reviews stated

Vet nice and will made

Quality of this gearbox looks to be top notch, and the black with red anodized accents is really impressive in person. First time I assembled the gearbox, it felt as if the gears were sticking at certain points so I loosened it, and re-tightened, but that didn't help. Finally, I took it all back apart and cleaned the grease out out of case and gears. I then bathed the gears in 100% alcohol and scrubbed them with a toothbrush. Now after reassembling a third time it runs perfectly, so my guess is that there were some tiny shavings from machining left over.
