8-Speed Automatic Transmission Assembly for 2014-2016 Land Rover

A quick look at your own vehicle makes sure the right transmission shows up:

• Confirm vehicle is a 2014-2016 Land Rover LR4, 2014 Range Rover, or 2014-2015 Range Rover Sport with the 3.0L Supercharged V6 petrol engine.
• Verify the vehicle is equipped with the automatic engine start-stop system (eco mode).
• Locate the green or blue metal tag on the left-hand side of the transmission case and match the OEM part number.

What the install really takes — plan and budget with confidence:

Special tools this job needs:

• Heavy-duty transmission jack
• Torque converter holding bracket
• JLR-compatible diagnostic scan tool (JLR SDD, Pathfinder, or GAP Diagnostic IIDTool)
• Fluid fill pump and fill adapter
• Engine support bar or fixture
• Torque wrench

Budget for these consumables at install:

• ZF Lifeguard 8 fluid (or equivalent meeting Land Rover specification LR023288)
• New plastic transmission oil pan with integrated filter (Land Rover P/N: LR065238), new pan bolts, and drain plug
• Torque converter input seal
• High-pressure transmission cooler-line flush
• Mechatronics connector sleeve seal

What your vehicle’s computers will need after the swap:

What’s involved: VIN-specific programming, security/immobilizer re-marriage (EGS/TCM virginization or cloning), and TCM adaptive relearn.

The Mechatronic unit (TCM) is integrated inside the transmission and is electronically locked to the donor vehicle's VIN. A used transmission will not shift out of Park or will enter limp mode without programming. Alternatively, the original undamaged Mechatronic unit can be swapped into the replacement transmission to avoid complex programming, though adaptations must still be cleared.

Pro tips for a smooth first start-up — hand them to whoever does the install:

• Torque Converter Seating: The torque converter must slide back and click into place three distinct times. If not fully seated, bolting the transmission to the engine will crush the internal oil pump, destroying the unit.
• Fluid Fill Procedure: The fluid level check must be performed with the engine running, vehicle level, and fluid temperature strictly between 86°F and 122°F (30°C and 50°C) using a diagnostic tool to monitor temperature.
• Start-Stop Accumulator (HIS): Ensure the accumulator on the side of the case is not damaged during transport or installation.
• Emergency Park Release (EPR): Ensure the manual emergency park release cable is properly adjusted and not binding.
• Adaptive Relearn Drive Cycle: A specific drive cycle of light-throttle upshifts and coast-downs is required after resetting adaptations.

Easy to get right once you know them:

• Buying the wrong variant (e.g., from a Dodge, Jeep, BMW, or a Land Rover with a 5.0L V8 or 3.0L Diesel) assuming all ZF 8HP70 units are identical.
• Expecting plug-and-play operation without programming the TCM, leading to immediate limp mode.
• Reusing the old plastic oil pan with a clogged integrated filter.
• Using cheap, non-specification generic multi-vehicle ATF instead of ZF Lifeguard 8.
• Failing to flush the transmission cooler lines, which recirculates debris from the failed unit into the replacement.

Not issues with the units on this page — the manufacturer documented these for every transmission of this family, wherever you buy one. Handy for your installer:
