TO35 oil leak

There are two seals on the transmission, one is just a bearing holder on the lower shaft and the other is the shaft that goes into the clutch (where the bad seal is likely to be). You can change these fairly easily, but having a shop manual to describe the procedure helps greatly. You have to drop the lower shaft to get the upper shaft out. Once you get the upper shaft assembly out, the seal is inside the outer housing of the shaft assembly. There is a split ring holding the bearings and inner shaft inside the housing and it can be tricky to get out, but be patient, it really isn't that hard.

I do not believe you can do it with out splitting the tractor. That said, I do not believe it is an impossibly hard task for a backyard mechanic. Though I will defer to other who have expierence to provide the help. John UK probally have a how to sheet on the subject.

However, I just started the engine this weekend after replacing the rear seal and I have oil dripping from the bottom of the bell housing. So mine might not be the best advice. I didn't think about the transmission seal. But, I drained the transmission and haven't refilled it, yet. So, I doubt it's coming from there.
