Hereís the walk through for the 2.5 T-Maxx transmission 3 speed conversion.
Itís quite long so I am posting it in 5 parts.
If you attempt this mod please be careful with the power tools or whatever tools you use and wear your safety glasses.
I canít be held responsible for any damages you may incur to yourself, the transmission or your Maxx. Higher speeds will result in more damage in the event of a high speed crash.
Take your time and read it thoroughly. I will be happy to answer any questions you may have.
