Why is the torque converter on my car slipping?
The torque converter changes the engine’s power into torque that the transmission can use. It’s a hard working, important component to the overall operation of the transmission. Without the torque converter, the wheels don’t get power or turn. Torque converters, like most other parts in a slipping transmission, become worn over time.
When to bring in a GMC Safari for a transmission problem?
“Limp mode” is a designed response that protects the transmission from damage. The “hard shift” feels bad, but it’s not harmful to the transmission. Just the opposite; the slippage that makes the shift smooth is harmful when it is excessive. So, talk with the service manager about the problem and tell him you will bring it in when it’s happening.

Solution: Sometimes, faulty solenoids can be replaced by themselves. Other times, they are integral to the valve body and the entire unit must be replaced. The transmission also could get damaged from the slipping this problem creates. In this case, the transmission may need to be built or replaced.
