How good is the 97 TRX300 tranny?

Hey guys,
Bought my first ever four wheeler a few months ago. It's a 97' TRX300 Fourtrax. It was a one owner. Always well maintained. Not a scratch on it except a dent in the top of the tank where a lawn chair fell on it. He never had it in the mud. Used it to give the grand kids rides around the yard. I have a moderately hilly 2 acre yard and hope to be able to use it for pulling carts, sprayers, rollers etc. Will this tranny hold up???

Thanks
