Operation CHARM: Car repair manuals for everyone.

Manual Downshifts

The shift solenoid valves do not control the initial 4-3 manual downshift. The 4-3 manual downshift is hydraulic, but the 3-2 and the 2-1 downshifts are electronic. The solenoid states will change during, or shortly after, a manual 4-3 downshift is selected.

Important: A manual First-Third Gear Ratio will occur at high speeds as an upshift safety feature. Do not attempt to perform this shift.

1. At vehicle speeds of 64-88 km/h (40-55 mph) in Fourth gear, release the accelerator pedal while moving the gear selector to Manual Third (3). Observe the following results:
^ The Torque Converter Clutch (TCC) releases.
^ The transmission downshifts to Third gear immediately.
^ The engine slows the vehicle down.
2. Move the gear selector back to Overdrive (D) and accelerate to 64-72 km/h (4-45 mph). Release the accelerator while moving the gear selector to Manual Second (2) and observe the following results:
^ The TCC releases.
^ The transmission immediately downshifts to Second gear.
^ The engine slows the vehicle down.
3. Move the gear selector back to Overdrive (D) and accelerate to 64 km/h (40 mph). Release the accelerator pedal while moving the gear selector to Manual First (1) and observe the following results:
^ The TCC releases.
^ The transmission immediately downshifts to Second gear immediately.
^ The engine slows the vehicle down.
^ Below 60 km/h (37 mph), the transmission downshifts to First gear.
