ive been told my tranmission is non serviceable. would it be worthwhile to replace the fluid or not ? i have around 200 hours on a 2004 model lt180 with the 2 cylinder kawasaki engine and freedome mulching deck. i have a flat 3/4 acre lot.

i do pull a thatcher in the fall.

could i use a boat oil pump to suck the quart or so of oil out of the top fill plug and repalce or take the tranny out and turn it over to drain ?
