Excessive shock when accelerating and decelerating
Probable cause(s)
- TCM defective (1.5 L engine)
- PCM defective (except 1.5 L engine)
- Low transmission fluid (HCF-2) level
- Transmission fluid (HCF-2) deteriorated
- Drive pulley, driven pulley, pulley shaft, steel belt, and pulley related parts worn or damaged
- Pulley pressure feed pipe defective
- Forward clutch defective
- Reverse brake defective
- Reverse brake piston defective
- Valve body assembly defective
- Joint pipes defective
- Stator shaft worn or damaged
- Torque converter assembly defective
- Torque converter ring gear worn or damaged
- Transmission assembly and drive plate installation defective
Notes
- Check the transmission fluid (HCF-2) level .
- Check the transmission fluid (HCF-2) condition. If necessary, replace the transmission fluid (HCF-2) .
- Check the drive pulley, the driven pulley, the pulley shafts, the steel belt, and pulley related parts for wear and damage. If there are worn or damaged, replace the transmission housing assembly .
- Check the pulley pressure feed pipe and the sealing ring for wear and damage.
- Inspect the clearance between the forward clutch end-plate and the top disc . If the clearance is out of tolerance, replace the input shaft assembly.
- Inspect the reverse brake piston and the O-rings. Check the spring retainer/return spring assembly for wear and damage. Inspect the clearance between the reverse brake end-plate and the top disc . If the clearance is out of tolerance, inspect the reverse brake discs and reverse brake plates for wear and damage. If the discs and plates are worn or damaged, replace them as a set. If they are OK, adjust the clearance with the reverse brake end-plate.
- Check the valve body assembly for wear and damage.
- Check the joint pipes and O-rings for wear and damage.
- Check the stator shaft for wear and damage.
- Inspect the torque converter assembly for wear and damage. If the torque converter assembly is worn or damaged, replace it as an assembly .
