Only you can be the judge of whether you need a warrant. Your problems with the General are not warranty issues. That is a result of trail hazards. If you got them covered, consider yourself lucky. The transmission on these are very reliable as long as you follow some basic rules.
1. if you plan on using a winch in deep mud, adding lots of lights and a stereo, get a second battery setup. The trans relies on proper battery voltage. If the buggy stays stock, the single battery is fine as long as it is stored properly when not in use. If you constantly ride with a half depleted battery, your going to have issues.
2. Don’t pulling someone out of the mud while in revers. It’s hard on the clutch packs.
3 If you riding real slow, uphill, and or crawling, put the buggy in low.
If you use common sense and keep an eye on your maintenance, you’ll be just fine. If I owned a Polaris or a Can Am, I would have a big warranty hands down. If your only using the buggy 300 miles a year, you biggest concerns aregoing to be fuel going bad while sitting and the battery going flat or low in charge. Keep an eye on both.
