460 industrial clutch ta problem???

have a 460 industrial gas. i think the clutch or ta is bad. put it in gear runs great, start pulling a hill.... yup slows down to a crawl!!!! tried to move some dirt, got a scoop, started spinning, tried backing out, put it ta low, sounded like a starter spinning with out ever hitting the flywheel! clutched it and put it back into high, sounded the same. turned the engine off and moved the lever back and forth a couple of times, started it again, and it was fine. (did not try to put it back in low again)

moved a couple of more buckets again with the same result..... slows to a crawl when i hit a hill (does not make a diff what gear i am in)

so.... is it the clutch, ta, or both? worth fixing or pass it down the road?

i checked the price for parts. not too bad except for the ta. how bad of a fix is it? or rather splitting the tractor at home? did my little mf35. not that bad. the 460 is a lot bigger tractor!

thanks for the help.

cnks thanks again for all teh help so far!!!

thanks every body for you help!!!

now if the ta is bad or slipping it could cause the same problem? i thought it was only working when placed in low and there had no effect on the regular drive line? or am i not understanding? (i vote for not understanding, thats why i am posting asking for help!!)

it holds going down hill, no over drive/ rev.
