Seven problems related to automatic transmission have been reported for the 1999 Oldsmobile Silhouette. The most recently reported issues are listed below.
The contact owns a 1999 Oldsmobile Silhouette. While the vehicle was parked the contact attempted to shift into drive gear and it failed to move from park to drive. The contact was able to place shift cable back in place and shift into drive. The vehicle was taken to an independent mechanic who stated the automatic trans axle range selector cable assembly needed to be replaced. The vehicle was repaired. The approximate failure mileage was 154,430.
Hard shifting on multiple occurrences. Seems associated with rapid speed changes. After turning car off and waiting a few seconds, the problem goes away.
After a few hours of highway driving, I pulled into my driveway and went into the house for about an hour. I came out later and drove to the store, and as I was pulling away from a traffic signal, the shifting of gears (auto-trans) was very forceful, bucking the van, like it was having trouble shifting. The first dealership (paul brothers) tried to explain that the fluid level was low by 1 quart, so they filled it. The problem continued off and on until I finally took it into a different dealership (koons - manassas), and they found that the problem was a bad pressure control selenoid, which they replaced. My concern is that not only may I have lessened the life expectancy of the vehicle due to the misdiagnosis, I also am concerned about a possible problem on other Silhouettes in the 15k-20k range of this happening to them as well. Possible recall issue for safety reasons.
Went up an incline and stopped, in the time it takes to move foot from brake to gas pedal, at the top of a hill, the vehicle begins to roll backwards when in drive gear. The vehicle stalled while in drive rolling backwards down the hill.
Automatic sliding door closed on its own. Also, automatic reverse mechanism did not work. Owner was pinned in door and injured when putting child in safety seat. The van is being looked over by dealership.
Transmission design does not prevent vehicle from rolling backward while in drive gear, resulting in vehicle stalling. Mjs.
Vehicle will roll backwards without stopping when in drive on a upward incline. The tourque converter does not stop the car from rolling back. This is very dangerous in traffic. The dealer and manufacturer stated that this is normal and cannot be repaired. I do not agree with this. A van should not roll back 20 feet while transmission is in drive.
