It's just another failed attempt at GM trying to build a diesel . . .
factory gearing has it cruising 65mph@2,500rpm in OD 4.10 gears & 30" tires.
Truck is real gutless doggy slow sluggish puke, that is also very unreliable only reason the diesel is still around is because i owe money on it other wise that 6.5 would have replaced by now 22 failed parts in 15 break downs over 18 months.
shame too only got 139K miles on it body is in awesome shape too boot . . .
I dug my little 88' Comanche out the weed's after sitting 5 years tossed on the road been a great truck performs flawlessly. . .
GM can build gas engines they can't build diesels period !
I'm a big fan of AMC's & GMC's my first GMC failure was diesel go figure . . .
I'll never ever never OWN a second GM diesel powered truck.
