EASY FIX!

Your Schro's are going bad in the 4WD HIGH Trans Case. This sucks i know. But i had the same problem berfore.

Unit will continue to work good in low range since the stress is less then on the HIGH range. I would never use the 4WD HIGH anyway...doesnt do much on the street...just tears up the gearing and schros.

Hope this helps,

THanks,

Mark

What makes a 1995 Turbo Diesel GMC Yukon accelerates on it own?


There should be a control unit on top of the engine that controls this to keep the engine at a certain temp which runs off the engine block temp sensore. I would try changing the sensors first located on the drivers side front of cylinder head and in the goose neck on top for one of the thermostats.It wouldn't be a bade idea to change the thermostats too at the same time.

I have a 2004 GMC Envoy XL and the high range 4x4 mode will not engage. The AWD system works just fine as well as the 4x4 mode in low gear. What is causing this?


Is the Service 4WD light coming on? Do the light on the 4x4 selector switch indicate the proper selection and are on steady after a few seconds? If there is no Service 4WD light on and the selector switch light are correct, the only place for the problem to be is the Transfer Case. Has the Transfer Case fluid been changed at 50K mile intervals? This is very important.

Bit of a long shot, but check the output of the throttle position sensor with a multimeter.

Also, check that the low range switch isn't continually reporting that you are in low range. The gearbox computer adopts a VERY harsh shift pattern in low range, holding gears until approx. 3500 RPM and even then producing very hard shifts.

Try unplugging the connector that carries the low range sense signal from the transfer box under the vehicle and see if that makes a difference.

Slips out of gear when in 4WD


Check the oil level in the shift on the fly (sotf) part of the axle thats the left of the front one - it holds about 1 pint of gear oil and gets missed at service time .

2004 f250 won't shift into 4wd low range.


I'm pretty sure the truck has to be at a complete stop with the transmission in neutral before it will accept your low range input selection. Unlike 4wd high.

4wd high range does not lite or engage


I had the same problem with my 98 sierra 4x4. Turned out that the electrical activator on the transfer case was not working. It will still go into 4 low but not 4 high. Replace the electrical switch on the transfer case and it should work again.

4 wd low range will sometimes engage 4wd high will never engage


I had a very similar problem with my 98 gmc 2500. The 4 low would engage - though the upshifts were erratic, but no 4 high though the light sometimes came on. I changed out the electric shift solenoid or whatever it is called, on the transfer case and it worked fine after that. A fairly simple fix that can be done in 15 minutes. Hope this helps.
