I have a 92 youkon and the flywheel is broke but i need to know what type of transmission i have so i can fix the problem.

Our 2002 Yukon has 74,000 miles. Recently, it's started a worrisome thing. When we accelerate from a full stop, for example at a traffic light, the car seems to make little "chugging" type noises. My husband describes them as almost like little hiccups -- not the sound, but the frequency because they aren't constant and once you get above about 15 mph they stop. We've noticed that this only happens in 4WD, not 2WD,and it seems to be getting more frequent. Accelerating quickly or slowly doesn't seem to matter. We've had our service station look at it 3 times and they can't find anything and say the car is in great shape. What should we do?

My air conditioniner only works on high speed and it blows a little bit when ur on the highway and does not always work the rear air always works good though

Only a very small amount of fuel comes out of the line when I turn the ignition. I can hear the pump, so I guess
it is not the pump relay.

Could the pump be bad if I can hear it? (only stays on
for about 5 seconds)

Oh, I have opened up the fuel line between the tank and
the filter, so the filter is out of the system.



do you have a diagram on the procedure to r&R evaporator?
I am going to do this project my self as I have more time than money.

While we were out or town "service 4wd" light came on. It had done this before when we hadn't used the 4WD in a while, so on a back road in Yellowstone we shifted into 4WD Hi and Low, everything did fine and went back into 2 normaly. Warning went off. The morning we were going to leave to head home we loaded up and put the vehicle in reverse to back out of parking place and the transfer case was in neutral. Would not go into 2WD immediately. We shifted into 4Hi then to 2WD, backed up to unlock 4WD and everything seemed to be fine. When we were two blocks from hotel, pulling onto the interstate it shifted back into neutral. After conferring with our family-all of whom are in auto repair-we drove home in Auto 4WD. When we got home transfer case would shift into and out of Auto, 2WD and 4Hi seemingly normaly-just would not stay in 2WD. Trying to shift into 4Low it would clunk like in tried to shift in and then back out. On dealer recommendation replaced transfer case when that didn't solve the problem replaced accuator. Now we seem to have Auto 4WD (at least in the 2WD app) and 2WD. Wont shift now into 4Hi or 4Low. No codes show. Any suggestions?
