I have a 2002 ad with a 6.6 diesel. My transfercase started making noise about 2 months ago.I checked my fluid and it was low,so i added fluid but could not find a leak.I then thought maybe the slip yolk seal was bad,having owned a jeep with one i know how the leak,this did not seem to stop the noise.I have 92000 miles on this truck and i went to change the fluid and found it had a burnt smell and it was like paste.Ill probrably have to replace the transcase but im not sure how tough a job it will be or whereto buy one reasonable,any suggs or has anyone had this prob?

Check your tranny fluid as well if your tcase is low. im assuming it's an automatic. your case could very well be leaking from the gasket that mates the case and tranny. They break down after a while and need to be replaced around the 100k mark. Or it may just be that the bolts have losened a bit and when the truck goes over bumps and such the drivetrain flex is opening up the gap due to the loose bolts causing it to leak while driving but not visible or obvious when the truck is parked and your under it. (this happened to mine once). Pasty ATF is an indication of water making its way into the case, so check your tranny to make sure its not similar. As far as replacing the tcase, Piece of Cake. You can find one for about 300-400 from a junk yard usually with a warranty. First, drain it. then, buy a gasket, pull the driveshafts off, and pop off the bolts mating the case to the tranny,allong with any electric harnesses. Use a floor jack to support the case while you unbolt it. then pull it off and lower the jack. A splined shaft will pull out of the tranny and ur' done. put on a new gasket with some sealer and insert the new case. To replace I usually just get under it and muscle it back in without a jack because mating the splines is hard with it on a jack. It should take about 30 minutes.

We were orginally thinking along those lines, especially after changing the fuel filter. The old fuel that drained out of the old fuel filter was the color of Coca Cola. We changed the filter twice that month, both times the excess fuel was Coke colored. While waiting for it to die, we removed the air filter and watched the injectors spray fuel until two seconds after the engine died. So, we are fairly certain we have the right amount of fuel at the right time. The problem is weird b/c it dies just like someone turned the ignition off. I believe our next step is replacing the ignition module. Apprecate your thoughts!!

I am in the same situation. They tightened up a few bolts and told me there was nothing they could do. They told me that the problem exists in only V6 models made in 2006. They gave me a notice sent to them by Chevy that addressed the problem. My advice to you is to take it to every local dealer and give them an opportunity to fix it! If they can not fix then they need to do something to make things right. The problem was not disclosed before the sale of the vehicle, therefore they are liable. P.S. Keep all of you paperwork and make sure they capture your complaints on that paperwork. Good luck!

Update, the headlights in my truck have mysteriously started working again. Periodically they will go out, but I simply turn the switch back to the parking light area and back on again and the lowbeams seem to work. Highbeams work as normal. My guess is that it is a short or connection problem somewhere. Hope this helps, its not right, but bareable for now.

Engine miss under load

Hello. I'm new to this forum and have a 93 Silverado with the 5.7 L engine (throttle body). It misses badly under a load (mainly going uphill). It misses a little at idle but the miss under load is making it almost undriveable. I had this problem about 12 months ago and did a complete tune-up which fixed it for several months. I had new plugs installed (they were already fouled) and replaced the MAP sensor a few weeks ago. This time the fix lasted less than a week. Oh yeah, have changed fuel filter to no avail as well. I need some help as to where I should go now... ERG system? ignition? timing? Any advice would be greatly appreciated!

did you check the oil pressuse switch, i think if the oil pressure drops the oil pressure switch will cut off the power to the fuel pump, or the oil pump is not producing enought pressure, its worth a try if everything else is ok
