| Buy a truck with a known limped transmission Should I consider buying a truck that has a known limped transmission? I have an opportunity to buy a nice 01' that the owner (my friend) said he has limped 3 times. Truck has EFI live DSP5. It still holds tunes 1-4 without problems, still pulls hard without slipping or limping, still shifts perfect. I was thinking of just keeping it on the eco tune and daily driving it. Do I have to worry about the transmission in the future? I can get it for a good deal, but not if I gotta buy a transmission. Guess just wondering how long the transmission will last if no longer abused or tuned as high.

| Each time it is limped, the clutches are slipped and become weaker each time. That being said, ive limped mine twice, and im not very concerned with it. i think it had alot to do with the timing on the junker bullydog. Now in your case, it was probably limped from raw tourqe from the EFI. Im still going to put EFI on my truck because i dont drive it all that hard and i have a somewhat calibrated foot so i usually let off before the 4-5 shifts. All in all, our 5 speeds just aint as tought as the 6 speeds, but if your not stupid with it, i would bet you will be fine for a good while.

| Yeah I am getting a good deal. I just don't want to spend $4000 on a transmission. Id rather put money in my lbz. I just want a duramax daily driver. Which would require the truck to haul around 10,000lbs also. Hopefully the trans will hold up.

| if it is your friends truck, then I would assume you have a fairly good idea on how he has treated the truck and how much and how hard he used the tunes. Limped 3 times is I guess not so bad, but as has already been said, each limp ads more wear on the clutches. I guess caveat emptor - buyer beware!
