Alright, test drive complete. Lets just say... that was a huge improvement! Definitely a lot less noise coming from the transmission. Took a pretty long test drive...
Down the street to a friend's shop, where it posed for some pictures.

Then down further to the local farm, and then after helping out in the repair shop for a while, she started right back up and drove all the way back without issue.

Well, there ya go folks. Always check your transmission fluid. It could be water, or it could be OEM Hy-Tran that's been there since the tractor was brand new
