One guy bought a YXZ and sent his trans out to a company (can't remember the name) and was getting their gear reduction set installed....sounded like at least the first 3 gear ratios were deepened....1st gear ratio was around 40% deeper tho...that would make it better, but I would think it still may need the recluse in it.
The newly released SS model may be the ticket having what sounds like fully automatic capabilities, but will it be low geared enough for seriously low speeds?
