The EX53-7000-AE part number corresponds to the ZF 8HP70 8-speed automatic transmission, specifically built for the Jaguar F-Type R (X152) with the 5.0L Supercharged V8 engine.

The “83TKM” in your query likely refers to a specific unit’s mileage (83,000 km), which is well within the healthy operational window for these robust gearboxes.

1. Technical Identity: ZF 8HP70

The “Quickshift” transmission is a masterpiece of engineering, capable of handling up to 700 Nm of torque. In the F-Type R, it manages roughly 680 Nm, providing the lightning-fast shifts that define the car’s character.

• Configuration: 8-Speed Automatic with Torque Converter.

• Compatibility: This specific code (EX53-7000-AE) is generally for Rear-Wheel Drive (RWD) models. While AWD models use a similar 8HP70, the output housing and transfer case mounting are different.

• Supercession: This part number is often cross-referenced with C2D41056 or C2D45620 in Jaguar’s official parts catalog.

2. Condition & Pricing (2026 Estimates)

At 83,000 km, the transmission is roughly halfway to its first major recommended “deep” service.

3. Vital Maintenance: The 100k Service

Even though Jaguar may describe this unit as “filled for life,” ZF (the manufacturer) recommends a fluid and filter change between 80,000 and 120,000 km (or 8 years). If you are buying a unit with 83k km, perform this service before installation:

• Fluid: Use ZF Lifeguard 8 (specifically for 8-speed units). Do not use Lifeguard 6.

• Pan/Filter: Like its predecessor, the filter is integrated into the plastic oil pan.

• Adaptations: After installing a new gearbox, the TCM (Transmission Control Module) must be cleared and “re-taught” using Jaguar SDD or PATHFINDER software so it can adjust to the wear patterns of the new clutches.

4. What to Check Before Buying

• Torque Converter: Ensure the converter is included (as seen in some eBay listings like this one). Replacing it separately adds $300–$500 to your cost.

• Mechatronic Pins: Inspect the electrical connector pins for any signs of transmission fluid “wicking,” which can damage the car’s main wiring harness.

• Input/Output Shaft Play: There should be zero axial play in the input shaft.
