I just got a 2002 yukon xl denali. It has 271.***miles its on its 5th or 6th trans and its about to go out. I just sold my 94powerstroke and my 98cummins so i have some money to put in it. I would like to build the trans and then the engine but i just dont know where to start. its not as simple to to mod as my trucks were.

 

either swap in a 4l80 trans or call performabuilt or flt and ask about a built 65e. what trans was in there now? stock 4l60?

 

it is a stock jasper rebuild

 

271,000 miles???

 

+1 on the 4l80

 

yup 271.***miles and still tickin. how much am im lookin to spend on a 4l80
