Trans has 78k I haven't changed the fluid iv only had it about 5k miles I jumped the shift pressure up 3psi and shift quickness down 3 and jumped the shift points up a little my first thought was valve body if I just drive normal it's fine the fluid is a little low but not bad I drove it for about 5 hours today and did fine all day
