Service 4WD light came on last night, causing shifting problems
On my 1999 GMC Yukon Denali (5.7L V8 ~213k miles) The Service 4WD light came on last night while I was driving, ever since the light came on when it tries to shift from 1st to 2nd the engine almost dies due to the rpm dropping so low, it has a fair amount of acceleration loss compared to before...- Chris_B
