What causes a loud bang when you put the car in reverse?
The problem is a bad valve body. It can be changed without pulling the transmission. It will cause a bang when putting the automatic transmission in reverse or drive. Very loud bang.
What kind of gears are used in reverse?
Manual transmissions use mostly helical gears, but reverse is a special situation that requires a different type of gear – a spur gear. The gears that make up the forward gear ratios are all helical gears. The teeth on helical gears are cut at an angle to the face of the gear.
When do I shift into drive or reverse?
Once in a while I will start the car, put in in reverse and it will thump into gear. Then, as I drive away it will thump with every gear shift. If I stop and turn off the engine, then restart it the transmission acts normal again and will continue to operate normal for several more days. 28 people found this helpful.
Why does my car make a clunking sound when I change gears?
A loud clunking sound came from the engine/trans whenever the automatic trans shifts when driving or simply changing the gear from drive to reverse (vise versa) Went to autozone, scanned the code and found out that my coolant tempreture sensor was unplugged.
