ON-VEHICLE SERVICE CVT 23A-54 2. Stall speed is high only when selector lever is in the D ranges. • Forward clutch is slipping 3. Stall speed is high only when the selector lever is in the R ranges. • Reverse brake is slipping 4. Stall speed is low when selector lever is in both D and R ranges. • Malfunction of the torque converter • Line pressure is low. • Low engine power HYDRAULIC PRESSURE TEST M1231205500567 CAUTION This test must be performed with the CVT fluid °C. 1. Start the engine and warm it up until the CVT fluid temperature reaches 70 to 80 °C. 2. Stop the engine and block the RH and LH rear wheels with the wheel chocks. AC507202 AB DR PRI PL FWD AC507203 REV AB 3. Install the following special tools at the hydraulic pressure outlet ports shown in the figure. • Oil pressure gauge <3.0 MPa> (MD998330) • Joint (MD998331) • Joint (MB992127) NOTE: . DR: Torque converter output pressure port 4. Restart the engine. 5. Make sure that no CVT fluid leakage is found at the special tool fixing points. 6. Pull the parking brake lever and fully depress the brake pedal. (Maintain this operation until WARNING For safety, operators must not stand in front 7. Measure the hydraulic pressure at each measuring point in the conditions specified in the 8. If not within the standard value, take necessary steps according to the hydraulic pressure test 9. Stop the engine. 10.Replace the O-rings on the plugs for each pressure port. 11.Remove the special tools and fit the plugs in the hydraulic pressure ports. 12.Install the plugs. Then, start the engine and check that no CVT fluid leakage is found around the Standard hydraulic pressure table Measuring conditions Standard hydraulic pressure (MPa) Selector lever Engine speed Forward Reverse Primary Line pressure Torque |
