A/T Pressure Test

1. Connect the A/T oil pressure gauge to the 4th clutch pressure inspection port (E).

1. Start the engine, and shift in the sequential shift mode in S.

1. Upshift to 3rd gear by pulling the paddle shifter + (upshift switch), and measure the 3rd clutch pressure at the 3rd clutch pressure inspection port (D) while holding the engine speed at 2,000 rpm (min −1 ).

1. Upshift to 4th gear by pulling the paddle shifter + (upshift switch), and measure the 4th clutch pressure at the 4th clutch pressure inspection port (E) while holding the engine speed at 2,000 rpm (min −1 ).

1. Upshift to 5th gear by pulling the paddle shifter + (upshift switch), and measure the 5th clutch pressure at the 5th clutch pressure inspection port (F) while holding the engine speed at 2,000 rpm (min −1 ).

   Standard | Service Limit
   3rd clutch (D) 4th clutch (E) 5th clutch (F) | 917−995 kPa (9.35−10.15 kgf/cm 2 , 133−144 psi) | 867 kPa (8.85 kgf/cm 2 , 126 psi)

1. Bring the engine back to an idle, then apply the brake pedal to stop the wheels from rotating.

1. Shift to R, then release the brake pedal. Raise the engine speed to 2,000 rpm (min −1 ), and measure 4th clutch pressure at the 4th clutch pressure inspection port (E).

   Standard | Service Limit
   4th clutch (E) in R | 892−970 kPa (9.1−9.9 kgf/cm 2 , 129−141 psi) | 843 kPa (8.6 kgf/cm 2 , 122 psi)

   Standard | Service Limit
   4th clutch (E) in R | 917−995 kPa (9.35−10.15 kgf/cm 2 , 133−144 psi) | 867 kPa (8.85 kgf/cm 2 , 126 psi)

1. Turn the engine off, then disconnect the A/T oil pressure gauges from the 3rd, 4th, and 5th clutch pressure inspection ports.

1. Install the sealing bolts in the 3rd, 4th, and 5th clutch pressure inspection ports with new sealing washers, and tighten the sealing bolts to 18 N·m (1.8 kgf·m, 13 lbf·ft). Do not reuse the old sealing washers.

1. If the pressures are out of the service limit, problems and probable causes are listed in the table.
