Re: Duramax/Allison downshift?
Ehh, there's not really up grade per say to those injectors, just the design of them the body's crack and leak fuel. Some people get 80k out of a set, some 200k. Mine were replaced at 72k when I bought my truck and we're failing at 170k when I eventually sold the truck.
The 5 speed alison is a great trans, in stock form if maintained. If there's been a tuner on it, and towed while the power was turned up that can cause issues internally. Once it limps once, it's just a matter of time until it does it again even easier.
