6-Speed Automatic Transmission Assembly for 2012-2013 Land Rover LR4

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

• Confirm vehicle is a 2013 Range Rover Sport, 2013 LR4, or 2012 Range Rover with the naturally aspirated 5.0L V8 engine.
• Verify the transmission has a traditional console-mounted cable shifter (M-Shift) and not an electronic rotary dial (E-Shift).
• Check the metal ID plate on the driver's side of the transmission case to confirm model 6HP28 and a 10-digit ZF part number starting with 1068 040 or 1068 050.

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

Special tools this job needs:

• Heavy-duty transmission jack
• Fluid transfer pump / pressurized filler
• JLR SDD or high-end diagnostic scanner (e.g., GAP IIDTool, Autel, Launch)
• Torque wrench

Budget for these consumables at install:

• ZF Lifeguard 6 fluid (Shell M1375.4 / Land Rover P/N TYK500050)
• New integrated plastic oil pan/filter assembly (Land Rover Part # LR007474) with gasket and bolts
• Mechatronic bulkhead connector sleeve (ZF Part # 0501 216 272)
• Rubber bridge adapter seal (ZF Part # 0501 215 783)
• Four rubber sealing sleeves (D-rings)
• Torque converter input seal
• Professional high-pressure transmission cooler-line flush

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

What’s involved: TCM adaptive relearn and VIN programming

The TCM is integrated into the Mechatronic unit and stores the donor VIN. To resolve, either swap your original Mechatronic unit into the replacement transmission (bypasses programming), or use a diagnostic tool (JLR SDD or GAP IIDTool) to write the vehicle's VIN and flash the software. A mandatory adaptive relearn reset must be performed before driving.

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

• Torque converter must be fully seated (typically three distinct clicks) to avoid crushing the internal oil pump upon bellhousing installation.
• Running fluid fill procedure must be performed with the engine running, transmission in Park, and fluid temperature strictly between 30°C and 50°C (or 40°C to 50°C) to prevent severe underfilling.
• Exhaust pipe clearance is extremely tight near the fill plug on the passenger side, presenting a severe burn hazard from the catalytic converter.
• Engine alignment dowels must be checked to prevent 'double-doweling' which causes crooked installation and bearing failure.
• Mandatory cooler line flush is required to prevent old debris from contaminating the replacement valve body.

Easy to get right once you know them:

• Reusing flattened or cracked Mechatronic bridge seals and D-ring sleeves when swapping the valve body.
• Filling the transmission fluid with the engine off, leaving the unit 3 to 4 liters short of fluid.
• Using cheap, non-spec generic multi-vehicle ATF instead of ZF Lifeguard 6.
• Skipping the TCM adaptation reset, causing the computer to apply high-pressure shift parameters from the old worn transmission to the replacement unit.
• Ignoring the professional cooler line flush, leading to immediate contamination and failure.
