Overview
Range Rover, Range Rover Sport, Defender 110, Discovery 5, Velar, and corresponding Jaguar models equipped with ZF 8-speed automatic transmissions generate significant heat during normal operation—especially in challenging terrain, towing, or warm climates. Factory transmission fluid temperatures can exceed safe thresholds, leading to degraded fluid viscosity, accelerated wear, and reduced shift quality.
This direct-fit transmission oil cooler is engineered to intercept hot fluid returning from the transmission, dissipating heat before it recirculates. By maintaining transmission fluid at an optimal operating window (typically 65–75°C), you preserve fluid integrity, improve shift response, and dramatically extend transmission service intervals.
Built to OEM specification with aircraft-grade aluminum construction, this cooler is a straightforward bolt-in replacement. No modifications, no rerouting of lines. Simply drop in and protect one of your Land Rover's most critical systems.

Installation
Difficulty: Intermediate | Time: 1.5–2 hours
-
Disconnect battery negative terminal and allow engine to cool for 30 minutes minimum. Do not work on hot transmission lines.
-
Safely raise vehicle on jack stands. Remove lower undertray fasteners to access the transmission cooler area.
-
Locate factory transmission cooler (if equipped) or identify the main transmission fluid line loop. You may see an OEM cooler already present on some models.
-
Disconnect fluid lines by carefully unscrewing the AN-style hose fittings. Have a small container ready to catch residual fluid (~200 ml). Immediately plug ports with rubber caps to prevent contamination.
-
Remove mounting bolts securing the old cooler (if present) or locate mounting points. Install supplied brackets using provided Grade-8 bolts. Torque to 15 Nm.
-
Position new cooler in the mounting brackets, ensuring it sits flush against underbody for airflow access. Secure with bolts.
-
Reconnect fluid lines to the new cooler's inlet and outlet ports. Use new crush-washer seals on all fittings. Torque AN fittings to 22–25 Nm. Do not overtighten.
-
Refill transmission fluid if any spilled. Check dipstick (or use BECM fluid level check on newer vehicles). Top up with OEM Jaguar Land Rover DM-24 or approved equivalent if necessary.
-
Reinstall undertray and lower vehicle. Reconnect battery.
-
Start engine and check for leaks around all fittings for 5 minutes at idle. No seepage = success. Drive gently for 10 km before full-throttle operation.
⚠️ Important: If you are uncomfortable working with transmission systems or have never replaced a transmission cooler, we recommend professional installation by a Land Rover specialist. Improper fitting can cause fluid loss and transmission damage. Victorious provides installation support: call +44 203 943 9919 for referrals.
