I have an 05 Vinson 500 4wd with low range. I was backing out of a mud hole in low range and all of the sudden I have no more tire movement. Forward and reverse low range do not work. Hi range 4wd and 2wd work fine. When I shift into low range and shift the transmission into first, it engages solidly with a slight jolt, just like normal, but when I give it gas, it nudges forward an inch or so then the motor starts to bog like something inside is holdign it back. Any suggestions?

 

Sounds like it's time for a new tranny to me. I know it's not much help and I feel for ya.

 

Sounds like you could have a problem with the sub-tranny. I had to replace a gear and dog in my Arctic Cat (same base engine). Mine would pop as a buddy shifted to low and did not lock it in (shifter was not fully in the notch). Even if it pops out only once the damage is done. It only takes a few thousandths of damage to ruin the undercut on the gears (although your problem is not exactly as I had).

Good thing is the sub tranny is easy to get to by taking the left engine crankcase cover off. Gears are between 40 and 60 bucks a piece and the tranny is relatively easy to work on.

Get a manual (book) and good luck.
