Manual Transmission System Description
Reverse Lockout System
At vehicle speeds of 12 mph (20 km/h) or more, the PCM, which monitors the signals from the output shaft (countershaft) speed sensor, activates the reverse lockout solenoid, which pushes the select lock cam into the locked position. As a result, the select lever cannot rotate to the reverse select position, making it impossible to engage the reverse gear. As the vehicle speed drops to 9 mph (15 km/h) or less, the PCM turns off the reverse lockout solenoid. The select lock return spring pulls back the select lock cam, enabling the select lever to move freely so the reverse gear can be selected.
General Operation
Improve operation feeling
The modified shift piece shape and clearance between pieces provide improved diagonal shift operation with reduced looseness. Reduction of double bump force
One-sided chamfering is applied to the synchro sleeve leading gear and gear dog, providing reduced "double-bump" load. MBS (Mainshaft Brake System) Mechanism
When the shift lever is moved to reverse, the 3rd-gear synchro is activated to brake the mainshaft, providing reduce reverse operation load. Constant mesh reverse gear mechanism
The constantly meshed helical gears provide reduced gear noise. |
