I got a 03, Auto, with 20's and have just a little over 115,000 miles on it and have not had no problems with this truck what so ever so it has been a good truck to me. I have changed the oil as required and pull a landscape trailer quite a bit during the busy season. I'm ready for its maintenence overhaul or tune up. I have noticed some delay on down shifting and even more so on acceleration, I'll floor it and doesn't jump like it should to, maybe a 2 to 3 sec delay, sucks for those light to light sprints. So I know things arn't not as crisp as new so can't compare. Sometimes the shift from P to D or other, I can hear the electronics clicking longer or sometimes it will stall from not completly going into gear. Which I think its just wear. Other than normal oil changes and maybe a tranny shift kit what adjustment is needed for some to bring this beast in shape for another 100,000 miles.
Thanks Gabe

 

I need to do a good trans service this spring too. What do these higher mileage transmissions need to keep them keepin' on.
