Shift Speed Specifications (Mph)
NOTE:
Shift speeds shown are approximate. All shift speeds may vary somewhat due to production tolerances and emission control equipment.
NOTE:
To determine deceleration shift speeds, release throttle once transaxle has shifted into 4th gear (O/D). Manually downshift shift lever into next lower gear and record speed at which downshift occurs. Continue downshifting and recording vehicle speed until transaxle has downshifted into low gear.
