the fully automatictransmissionhas become optional or standard equipment on most passenger cars. When the transmission is in the drive position, the driver has only to depress the accelerator pedal, and as the car gathers speed the transmission will shift automatically through its entire forward range...
A shift pattern control in which upshifting and downshifting is modified in response to a detected condition of above normal road load. The above normal loading may be due to a number of conditions such as trailering, steep grades, unusual aerodynamic loading, or any combination thereof. A loa...
The Signs of Automatic Transmission Won’t Shift into 3rd Gear The problem could occur in a couple of forms that can be easy to recognize and follow. First, you can notice that the transmission shifts into the first and then to second gear but does not move into the third gear. It seem...
PROBLEM TO BE SOLVED: To provide a shift control method of an automatic transmission for a vehicle capable of increasing driveability by reducing up-shifting time in a high throttle opening area. SOLUTION: When an up-shifting is performed by discharging hydraulic pressure from a release side engag...
If your car stops for a long time, shift to N. When climbing a steep hill or going down a mountain pass, do not use D but shift to a smaller gear to reduce the oil boiling in the transmission. Final Thoughts Hard shifting refers to abrupt and harsh gear changes that can occur in...
