Question about 1999 GMC Yukon

1 Answer

My Yukon has 226,000 mostly highway miles on it.

My Yukon has 226,000 mostly highway miles on it. It is on its second transmission. I'm recently the second owner. I know the first owner so the trans info is correct. It was changed about 80,000 miles back..My problem is I went to take off from a red light and the transmission...or maybe a bit further back in the drive shaft..made a loud clunk sound. Then I lost all forward gears. No D L L1 etc. and I even tried 4High and low..nothing..but I still had (have) reverse gear. I can shift and go backwards but not forward. Is my tranny shot? Thanks....Owner in Omaha

2007 GMC Yukon Denali engine reduced power


there are 2 conditions that will trigger this SAFE MODE that the engine is running in. The first is transmission over temperature when the sensor in the transmission senses over-temp situation it reduces engine output to no more than 1500 rpm. The second is low oil level in the engine, which will also limit engine rpm to 1500. One of those sensors is bad or the wiring for one of them is damaged. This SAFE MODE is designed to protect the engine or transmission from further damage.

I just brought a yokon XL with 226,000 miles for $4,700 the engine light came on saying service soon is it worth it?


You can take the car to any autozone or advanced auto parts. Tell them your engine light is on and you would like it tested. They will come out to your car and find the exact code and tell you what is wrong with it. It doesnt cost anything, it may be an inexpensive fix, and at least you will know what is wrong with the vehicle.

It sounds like your fuel filter has got to the end of it's life and needs to be replaced. Once the fuel filter get's to dirty, the fuel pump can no longer keep the proper fuel pressure to the fuel injectors to have them work properly. The fuel filter should be replaced once a year or 30,000 miles to ensure that it's always clean. A dirty fuel filter will make the fuel pump work harder and shorten it's life time causing a costly fuel sending unit replacement. Good luck and be safe.

Hesitation / missing / car shakes


Hello;
The problem is most likely break down of the spark plug wires. The demands on the spark during acceleration and load destroy the wires as they age. I would start there. Hope this helps.
