I thought the drive belt was stretched, but turns out the trans was dry with no fluid in it. I used Heavy duty SAE 30 weight motor oil for the transmission fluid. This is my personal mower.

" Mustie1" was the YouTube channel I watched go check out his channel as well. The axel seal part number is tt-187t0134280.
