What happens when your transmission fluid level is low?
Transmission Surging. A surging transmission, a transmission that causes a vehicle to lurch forward and then fall backward during normal operation, is often the result of a low transmission fluid level. The surging and erratic transmission movements are caused by insufficient fluid force during all ranges of transmission operation.
What happens if the transmission is overfilled with fluid?
The transmission is vented so that pressure won’t build in the unpressurized areas. Transmission fluid can leak out these vents if it is too high. The seals higher in the transmission may also leak, but these seals are not pressurized.
What causes transmission fluid to leak from vent?
Leaking Fluid. Overfilling the transmission fluid will not cause seals to break, but they may leak. The transmission is vented so that pressure won’t build in the unpressurized areas. Transmission fluid can leak out these vents if it is too high. The seals higher in the transmission may also leak, but these seals are not pressurized.
Why does my transmission fluid keep slipping in my car?

Saab transmission on a 2003 9-3 Arc is being replaced with a used unit. What are the things to be checked before the new transmission is fitted? The biggest cause of Saab transmission problems is coolant leaking into the transmission fluid through the transmission cooler in the radiator.
What happens when you change the ATF in a Saab?
The ATF will start draining out slowly when the bolt is almost at its end. Removing the bolt will make the fluid gush out because it’s a pretty large opening. Because the engine is warm/hot, this fluid can be very hot so be very careful not to get it all over your hands or arms. It really can cause severe burns.
Where is the drain bolt on a Saab 9-5?
The drain bolt is located to the right of the exhaust when looking from the front of the car. It’s the only 24mm bolt in that area so you can’t mistake it for anything else. There is not enough room for a socket so an open-ended or ring wrench/spanner is needed.
