It has 103,000 miles on it, I bought it new. I've read the life of these transmissions is btw 120,000 & 130,000 miles. Since I retired I drive it 5/6 thousand miles a year with some towing of a 17 ft aluminum boat. Once in awhile use 4wd. At my age, 72 and as well as it runs I'm hoping it lasts as long as I do.

I've never had the transmission serviced, still running the original fluid and filter and never had a problem with it. Shifts where it should, no slipping, doesn't use fluid and the fluid is still the original color with no burned odor.

Service it or leave well enough alone? If I service it take it to the dealer or to a transmission shop? Thanks.
