How does reverse gear work in an automatic transmission

The vast majority of automatic transmissions utilize PLANETARY GEARSETS. These are composed of a central or "sun" gear, which is surrounded by and in mesh with 3 or 4 "planetary" pinions. These planetary pinions are in turn surrounded by and in me.

Why is there a grinding sound when I shift into reverse gear?

 · If you are grinding reverse gears it means the gearbox (also known as a transmission) has not fully disengaged from the engine and the gears are still rotating. One trick to eliminate the problem is to momentarily shift into a forward gear before quickly shifting into reverse.

How to Avoid Wheel Loader Transmission Repairs Caused by

 · In a heavy production environment, wheel loader operators can be under a lot of pressure to keep their numbers up, particularly in the age of labor shortages. One of the most common shortcuts is high-speed shifting, when operators fail to make a complete stop when shifting between forward and reverse.

Loader Backhoe Common Faults

 · 2) The belville washer in the forward pack breaks into pieces (due to heat or excessive clearances caused by worn plates) - this often causes the forward pack to sometimes lock up permanently, so when reverse is selected the transmission locks up trying to drive in forward & reverse at the same time.
