Four problems related to automatic transmission have been reported for the 1998 GMC Sonoma. The most recently reported issues are listed below.
I am the original owner of a 1998 GMC Sonoma purchased new in February of 1999. Vehicle properly maintained driven as a commuter vehicle approximately 7,400 miles per year. It is equipped with the 4l60e transmission, which is clearly defective. 59,000 miles begins to surge and slip. Acceleration is greatly reduced with harsh shifting. Greatly compromising my safety. Entire transmission needs to be replaced at a cost of $3100. 00 GMC will not reimburse repairs to my vehicle. My claims were "denied" by the district representative.
The complaint is about my transmission in my 1998 GMC Sonoma. Engine service light came on so I took the truck in for service. I was told that the transmission needed to be rebuilt or replaced as per the service bulletin. A $2,200-dollar fix. The truck is not quite 3 years old though I have 59000 miles on it. I can tell you that Im the only one that has driven this truck and it has hauled no more than groceries I called the customer care center and gm has said they would pay 40 percent of the repair ref case number: c05710638. At first I thought this was better than nothing. But I believe there is a major problem with the transmission and general motors should stand behind the product due to the nature of the failure, warranty or not. This is not right. This is a major part of the vehicle and should not have gone bad this quickly. I will continue to do all the research I can to show that this failure is not normal. If a service bulletin was issued then I think it was a known problem, gm has admitted that they have seen this problem before but because the vehicle is out of warranty this is all will do.
Transmission was noisy at any speed, dealer determined a bearing needed to be replaced in transmission. Mileage at repair was 30000. At this time bearing neeed to be replaced again.
