Does anybody know of any sites that will tell you what the drivetrain specs on different trucks are ? I have been searching and the closest I have found only give you stuff like 4 speed transmission instead of actually what it is.. The trucks I'm specifically looking for are 95-98 Yukons, Tahoes and Suburbans.. I'm looking for what exactly comes in each truck like 4L60e or 700r4 not just 4 speed.. I have found some sites like what I want for the older trucks just not any for the newer ones..
