SOURCE: lost reverse on GMC Yukon Denali vortex drives

WOW sorry to hear that.

this is a common problem with the 4l60e transmission, what has happend is the gear has sheared off the back of the sun shell, you should have lost reverse and if you will watch your tachometer the next time you drive you will notice you allso lost forth gear.

you will nedd to have the transmission removed and disassembled for the new sun shell, make sure you get the hardened sun shell, this is not a rebuild but simply a repair. you can get a stock sun shell for about $65.00 or a heavy duty one for about $100.00, make sure you find a good tranny guy to provide the labor, oh the transmission paper rubber kit "reseal kit" shouldnt be more than about $80.00

good luck

30 MINUTE RELEARN PROCEDURE
  1. Turn ON the ignition, with the engine OFF.
  2. Attempt to start the engine, then release the key to ON, vehicle will not start.
  3. Observe the SECURITY telltale. After approximately 10 minutes, the telltale will turn OFF.

What type of oil pump is on 1999 GMC Yukon V8 5.7L 350? Is it 3/8 or 5/4, I am getting the motor rebuilt.


If you are referring to the pickup screen tube size, it would be either a 3/4inch or a 5/8 inch Most rplacement pumps use the 3/4. If in doubt, buy the pump and pickup at the same time and get both of them in the same size.

How do i set the rocker on a 1999 5.7l vortex stadicly


Static rocker adjustment is done by tightening the rocker down (with the cam lobe for that valve "out of tension"...turn the engine by hand to adjust any that have lobe pushing up on the lifter. Tighten the rocker while turning the pushrod with your fingers. When you cannot turn it easily, turn back a quarter turn or less, till you can turn it again. You will still need to do a "running" adjustment but static adjustment will get you in the "ballpark" for starting engine..
