Description
The ZF 8HP automatic transmission in the 2021+ BMW M2, M3, and M4 is designed to handle the high output of the S58 engine. However, when combined with high-performance upgrades and track driving, the factory transmission cooler struggles to maintain optimal temperatures. Overheating can lead to slower gear shifts and potential transmission damage.
The do88 Performance Transmission Cooler provides a drop-in replacement for the OEM cooler while significantly enhancing cooling efficiency, helping to maintain consistent transmission performance in high-stress conditions.
Key Performance Advantages
- 71% Increased Core Volume – A larger cooling core ensures greater heat dissipation, preventing transmission overheating.
- 50% Larger Cooling Surface Area – Improved efficiency allows the transmission to run at optimal temperatures during aggressive driving.
- Optimized Oil Flow – Features harmonica tubes with internal channels to maximize cooling efficiency without restricting flow.
- Increased Cooling Capacity – 42% increase in oil volume (8.5 dl vs. 6 dl) for better heat management.
- Dual-Pass Cooling Design – Ensures the fluid stays in the cooler longer for superior temperature regulation.
- OEM-Style Quick Connect Fittings – Easy installation with no need for modifications.
