hey there,, I have a 001 that I converted to a t1000 ,,, are u getting the 2 speed version,, the 002 2 speed?? pretty sure they don't make a 3 speed,, I think a company gtb does for the Baja's for like 240 bucks or so,, anyway,,, if u research,, a lot of problems with king motor 2 speeds,, on the site the cars are out of stock I c,, and if u look at buying the 2 speeds separate, right now they are marked down on clearance for 99 buck and say have no warranty due to one way bearing problems etc,, they are not reliable,,, most reviews ive read whether they were king motor, rovan , hpi Baja,, almost all transmission kits have there own issues of reliability ,, and most convert back to single speed,, as far as conversions go,,, the input shaft that is turned by the engine that goes into the transmission I believe would have to be changed,, thus,,, complete transmission tear down will be neaded,,, just look up Baja turtorials on you tube on the hpi Baja,, they pretty much have vid series step by step on there for a complete build.. of a Baja,,,,,,, which the km is based off of ..... ive wanted myself to get a 2 speed,, but any of the kits out there,, ive read on are just not reliable,, and pain to adjust, fix , etc,, and not really too useful if u plan on driving offroad.. would probably be fun for a while for speed runs,, till parts wear out,,
