Pretty much bullet proof trannys. Used quite a bit in medium vocational trucks and larger RV's. Being that they run on there own computer you can change quite a bit if you know what you are doing(or know a Allison mechanic). How long it will last will depend on how you drive and how the previous owner did, maintenance, etc
