5410 Transmission won't shift in Cold weather

My 5310 had this problem, drill a 1/8 inch hole thru the bottom plate and let the water out, cured my problem

My 5303 would do the same thing. I took the cover off the bottom [4 bolts I think]. I warmed the area first with a propane torch as I didn't have electric where the tractor was kept. A lot of water came out as cover came loose. No problems after that. The place I bought the tractor from replaced the rubber boot just before I bought it so it must of been cracked.
