Common problems:
*Clutch Sticking: Worn or damaged clutches can stick to each other, causing shift delays, slippage, or vibration.
*Low Oil Pressure: Insufficient oil pressure can lead to poor shifting, slipping, or even transmission failure.
*Damage to the hydraulic control unit: The solenoid valves and other components in the hydraulic control unit may fail, causing shifting problems.
* Worn gears and bearings: High loads and improper maintenance can cause premature wear of gears and bearings.
* Fluid Leaks: Transmission fluid leaks can lead to low fluid levels and shifting problems.
Brand specific issues:
*Slipping in First Gear (Jatco Models): A weak torque converter or worn clutches can cause slipping in first gear.
* Vibration when shifting (Jatco models): Damaged clutches or faulty hydraulic valves can cause vibration when shifting gears.
*Unable to shift into second gear (Punch Powerglide models): A broken valve in the hydraulic control unit may prevent shifting into second gear.
* Gear Shift Delay (all models): A faulty automatic transmission control module or transmission speed sensor can cause shift lag.
Problems associated with improper maintenance:
* Contaminated Fluid: Failure to change or use the wrong transmission fluid can result in sludge that can clog hydraulic lines and cause shifting problems.
*Overheating: Towing heavy loads or prolonged city driving can cause the transmission to overheat.
*Improper Installation: Improper installation of a new transmission or components can cause leaks and other problems.
