Torque Lock (Automatic Transaxle) If you are parking on a hill and you don't shift your transaxle into "P" (Park) properly, the weight of the vehicle may put too much force on the parking pawl inthe transaxle. You may find it difficult to pull the shift lever out of "P" (Park). This is called "torque lock.'' To prevent torque lock, always be sure to shift into "P" (Park) properly before you leave the driver's seat. To find out how, see "Shifting Into "P" (Park)" in the Index. If "torque lock" does occur,you may need to have another vehicle push yours a little uphill to takesome of the pressure from the transaxle, so you can pull the shift lever out of "P" (Park).
