well I'd not touch a early 2000 gm product with your lips, so I guess we're all safe.
enjoy your rattling apart interior and steering that wears out in 60k.
Thanks both of you. It's these reasons i'm not too terribly smitten with the 01 vs truckin down the road in my obd1 454 and 4L80E. As it is for all intents really serviceable / reliable as shit / 9 towing 11 empty / strong fucker / i'm the 2nd owner.I bought my 2001 GMC new with the Allison and the 8'1.
Strong motorpulls hard.
So far I have replaced a Fan clutch, and the 10 foot + cable to the starter.
No replacement cam sensors are availble, seem GM switched to a different style in 02', Raylar has a fix that includes a new style sensor, a new cam gear , and a new timing cover, ( I still have the stock one in there with no problems so far).
Crank sensor requires a double jointed midget to change and if you mess it up removing you will be dropping the pan to remove the broken part. Dealer replaced mine under warranty.
Grease fitting on top of steer idler will cost you a new idler if not seviced.
10 mpg empty or towing,
The shift mapping in tow haul sucks, In tow mode, down hill, stomp the brake and the Allison will down shift 2 gears, tach jumps to 4k right rear wheel tries to lock up and gets scetchy real quick pulling the car hauler with a rig on it.
Love the truck I have decided to keep it as long as I can, New shit way too expensive and I don't need a coal roller'....
Yep.10 mpg empty or towing,
someone last page said it takes 8qtI had an 01 with the 8.1, the dealer replaced the crank sensor under warranty. On occasion I would have to add a quart of oil in between oil changes. Those were about the only two issues I had with the truck.
