Ok, well, as i wrote before, i used 80w90 in the transaxle and sae30 in the hydrostatic pump, TWO SEPERATE UNITS although they are bolted together. the pump has it's own sae30 and the transaxle has EP90 oil. There are NO NOISES from either apart from the renowned whining from the transaxle which i have heard many people report they have in theirs. The hydro pump was filled to the bream, then some added to the res when it was replaced. the transaxle was filled to the front filler plug as it states to do BUT it was 80w90, not EP90. i will drain it and refill with EP90 BUT as i stated before, it was doing the same thing before i touched any oil anywhere, perhaps the old oil was the wrong sort too. Anyway, i will find out soon enough after i refill it.......Will post again with a result but i think it won't change.
