ok this morning i was picking up a friend to work w/me. and I was fooling around trying to wake him by doing a brake stand in his driveway. :badidea: But my truck reved and wouldnt spin the tires. im going to get a trailer soon becouse i have more equipment than space in this blazer. (worried that it'll slip) but would a tranny Shift Enhancer fix this problem? i checked the fluids. looks fine maby a little too much oil. but any help would be appreciated. i just think w/the torq of this truck it should be easy to spin em up. not that i do that allot.

It has more to do with how the brakes work off the motor. It's easier to scratch the tires without the brake than with.

shouldnt the motor push threw the rear brakes? my ol grand national pushed threw the brakes and would leave a nice smoke show. but i am a newb to the diesels. would the ecu let the tranny slip? how does the brakes work off the motor?

Could have something to do with how your rear brakes are adjusted. Lots of shops set em up too tight.

The brakes are powered by the powersteering pump, via the hydroboost. The more you rev the engine the greater the force powering the brakes.
Not the same as vacuum assist on a gasser, where the vac comes from the intake and when you rev it the vac drops, right?

thx guys, im starting to fiqure diesels out. ill have many more dumb questions in the future. (just got to think some up) but thanks for being a helpful forum
