"D" Range Test

WARNING: This page is about a different car, the 2003 Toyota RAV4, 2002 Toyota RAV4, 2002 Toyota Highlander, 2001 Toyota RAV4, and 2001 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.

Shift into "D" range. Hold accelerator pedal constant at full throttle. Check 1-2, 2-3, and 3-OD lock-up and upshift points. See SHIFT SPEED SPECIFICATIONS and LOCK-UP SPEED SPECIFICATIONS . If shift points are not as specified, diagnose by symptom. See SYMPTOM DIAGNOSIS under TROUBLE SHOOTING.
Use procedure outlined in step 1 to check for shock and slip between 1-2, 2-3, and 3-OD upshifts. If shock is harsh, line pressure may be too high. Check accumulator or check ball.
Run vehicle in "D" range lock-up or overdrive gear. Check for abnormal noise and vibration.
NOTE: Check for cause of abnormal noise and vibration must be made with extreme care as problem could be due to an unbalanced drive axle, differential, tire, torque converter, etc.
While running in "D" range, confirm correct kickdown vehicle speed limits for 2-1, 3-2, OD-3 shift points. Check for abnormal shock and slip at kickdown.
Check lock-up function. Drive vehicle in OD gear of "D" range with lock-up on. Hold vehicle speed steady at about 47 MPH. Lightly depress accelerator pedal. Ensure engine RPM does not change abruptly. Large increase in engine RPM indicates lock-up function is faulty.
