2010 Acura TL Owner's Manual - Page 469

Manual Transmission Recommended Shift Points Drive in the highest gear that lets the engine run and accelerate smoothly. This will give you good fuel economy and effective emissions control. The following shift points are recommended: Shift up 1st to 2nd 2nd to 3rd 3rd to 4th 4th to 5th 5th to 6th Normal acceleration 17 mph (28 km/h) 27 mph (44 km/h) 36 mph (58 km/h) 41 mph (66 km/h) 44 mph (71 km/h) Engine Speed Limiter If you exceed the maximum speed for the gear you are in, the engine speed will enter into the tachometer's red zone. If this occurs, you may feel the engine cut in and out. This is caused by a limiter in the engine's computer controls. The engine will run normally when you reduce the rpm below the red zone. Before downshifting, make sure the engine will not go into the tachometer's red zone. 466 2010 TL
