• Transmission fluid leaks
• Low transmission fluid level
• Transmission overheating
• Visible damage to cooler lines or fittings
• Transmission shifting problems
• Transmission temperature warnings

WHY REPLACE A TRANSMISSION COOLER LINE KIT?

Damaged, leaking, or restricted cooler lines can affect transmission fluid circulation and cooling. Replacing the line kit and fittings can help restore proper fluid flow and reduce the risk of transmission overheating or fluid loss.
