Gary, Doc, Shiden.... etc.. I've heard mention on this group before of why not to have a 4L60E flushed. My 2000 GMC Sierra SLE 4x4 has 59,800km (35,000 miles....yeah i'm from Canada) and dealer suggests that I have the tranny flushed. Tranny has not yet been touched and works great. Are there reasons not to have this done? Please fill me in. Could you please give me suggestions? I never haul anything other than my 500 lb snowmobile...about 2-5 times per season. Oh yeah and my secretary to lunch every week.....but she doesn't count as heavy hauling! Thanks for your time, Glenn
