Here's why:
* Oil specifications are very important: Different transmissions have different requirements for oil viscosity, additives, and compatibility. Using the wrong oil can damage the transmission.
* Manufacturer recommendations are crucial: The best source of information is always the manufacturer's manual for the specific TD 25 model you have. They will specify the correct oil type and specifications.
* Age and condition: The age and condition of the transmission may also affect the recommended oil.
How to find the right oil:
1. Consult the owner's manual: Look for the section on fluids and lubricants.
2. Contact International Harvester (IH): They can provide you with specific recommendations for your model.
3. Check with a reputable equipment dealer or mechanic: They can help you identify the correct oil based on your machine's specifications.
Remember: Using the wrong oil can lead to serious damage, expensive repairs, and even safety hazards. Always prioritize using the manufacturer's recommended fluids for your equipment.
