do yourself a favor and buy a service and owners manual for that machine before you tear it up.
also.. if you don't know what's int here.. i'd give it a full service.
utf meeting m2c134d can be put in all 3 sumps.
hyds fill under front of seat, diffy fill aft of seat. trans fill on tranny by shifter.
you COULD use 80w90 in trans and diffy.. but not in hyds. utf easier.. 1 fluid to buy
