A/T System Description - Shift Lever Mechanism

Shift Lever Mechanism

The shift lever has five positions; P, R, N, D, and D3. D has two modes; automatic shift mode and sequential sport-shift mode with the shift lever moved to M. The shift lever shifts out of P by holding in the shift lever button, and moving the shift lever into any available gears. The shift lever is engaged with the shift lever link in P, R, N, D, and D3. This unit shifts the transmission using the shift cable connected between the shift lever link and the transmission control shaft.

In M, the shift lever is disengaged from the shift lever link, and the shift lever can be used to shift gears manually between 1st though 5th, much like a manual transmission.






Shift Lever Mechanism in M Position

When the shift lever shifts to M, the shift lever is disengaged from the shift lever link/shift lever pivot. The shift lever link lock pops up to engage with the shift lever bracket base; the shift lever link and the transmission are held in D. The shift lever link lock is spring loaded, it pops up in M, and does not engage the shift lever link in any position except M.






The shift lever fits into M by using a detent plunger with a spring. When shifting to upshift and downshift position, the detent plunger is depressed by the detent bracket wall, and detent plunger spring puts the shift lever back into the neutral position. The detent plunger also works in P.
