* Sealed System: Most modern automatic transmissions are sealed systems designed to hold a specific amount of fluid throughout their lifespan. Adding more fluid can actually cause problems.
* Fluid Contamination: Adding the wrong type of fluid can contaminate the existing fluid and damage the transmission.
* Overfilling: Overfilling the transmission can cause excessive pressure, leading to component damage and leaks.
* Fluid Degradation: Transmission fluid degrades over time due to heat and wear. Simply adding more fluid doesn't address the issue of degraded fluid.
What to do instead:
1. Check Fluid Level: Consult your owner's manual for the correct procedure to check the transmission fluid level. This should be done when the engine is warm and the vehicle is on level ground.
2. Fluid Change: If the fluid level is low or the fluid is discolored or smells burnt, you need a complete transmission fluid change. This is best done by a qualified mechanic who can use the correct tools and procedures.
3. Use Recommended Fluid: Always use the transmission fluid specified by Toyota for your Land Cruiser 100 series. The correct fluid type is critical for proper operation and longevity.
Important Notes:
* Don't attempt a transmission fluid change yourself unless you have the experience and proper tools.
* If your Land Cruiser is experiencing transmission problems, consult a qualified mechanic for diagnosis and repair.
By following these guidelines, you can help ensure the proper operation and longevity of your Land Cruiser's automatic transmission.
