If all goes right with the deal I will be picking up an 03 2500HD Duramax with the Alison Trans with 56k on it. This will be my first Diesel and i am curious as to what to expect. I have read alot of guys run additives when they fill up is there or what is the need for this? Also I hear alot of guys talking about waiting to change oil but ever 5-10-15k miles what is a good intervel on a gas motor i have always done it at 3k.
I have also read some people talk about T-case issues are there common problems with them? And i have also heard alot about Injectors what are the signs they are going bad and did GM extend the warranty on them?
Thanks guys for the help I am sure I am going to love this truck just want to make sure I do things right.
