    The older stock 3906 E Maxx has a 2 speed transmission.

    Traxxas P/N 3998 is a two speed conversion kit for the E-Maxx 3905/3903/3908. It's about 45 bucks and comes with all the instructions.

    I have that in my Maxx and is very useful when you need some extra torque.

    I do have the newest e-maxx 3908, so it dossen't come with the two speeded one. Can you please link where i can find the kit? i do found it quite boring to not be able to crawl. the diffgears just spin when it can't move the tires.

    Putting in thicker diff oil will help reduce the "Diff out" effect. I personally run a mixture of Silly Putty and thick diff oil.

    You can also spool the diffs. This locks the diffs so there is no slipping. Bad side effect is that you can tear up the gears inside the diff if you drive it a lot on non slip surfaces like roads or parking lots.

    I have a 2 speed kit if you are interested in it. Send me a pm if you want me to dig it out. It is new and never used. I also may have a TQ rx and tx. I will have to check on the rx and tx.
