But adding performance parts and tuning on top of that can overwhelm the original cooling system, especially during track driving, and an overheating transmission means slower gear changes at best, and potential transmission damage at worst.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003edo88's engineers redesigned the transmission cooler's core specifically to address this, increasing core volume by \u003cstrong\u003e71%\u003c\/strong\u003e and active cooling surface area by \u003cstrong\u003e50%\u003c\/strong\u003e compared to the factory unit, while maintaining similar oil pressures. Harmonica tubes with internal channels ensure optimal oil flow and maximum surface contact, and the dual-pass design keeps fluid in the cooler for longer, allowing genuinely more heat to dissipate before it re-enters the system.
