With cutting-edge engineering, dynamic driving, and a luxury finish, Jaguar is one of the few cars that offer the perfect blend of performance and luxury. At the heart of its dynamic drivability, it presents its advanced transmission system that is responsible for smooth and seamless gear shifts. Transmission in modern Jaguars features Jaguar’s advanced technologies and systems, such as the ZF 8-speed automatic transmission, adaptive shift strategy, Jaguar Sequential Shift system, and ‘Sealed for life’ design. These features, on the one hand, provide exceptional transmission performance and, on the other hand, require meticulous servicing by expert technicians. Dell’s Service Center provides expert Jaguar transmission services in Green Bay, as we are the premier independent auto service shop specializing in European auto brands.
When To Schedule a Transmission Service for Jaguar?
Modern Jaguar transmissions feature a ‘sealed for life’ design, which Jaguar claims does not require servicing as part of scheduled maintenance. However, the claim is typically about the warranty period or about a standard of 100,000 miles. That’s why manufacturers and independent experts recommend servicing the transmission system in Jaguar around that period. Moreover, the transmission interval should be about 60,000–75,000 miles, or every 8 years, primarily if the vehicle has been driven at high speeds, engaged in aggressive or sporty driving, experienced heavy stop-and-go city traffic, or towed or carried heavy loads.
On top of that, if there is any transmission malfunction in the system, then transmission services are also needed. The malfunctions often manifest as warning signs indicating the need for service. These malfunction signs include;
- If you feel a noticeable jolt or lag when the car shifts gears under light acceleration, it is called gear hesitation or jerking, and is indicative of the need for transmission service.
- When the engine RPMs go up, but the car doesn’t accelerate proportionally, it is called gear slipping. It is also another indication of a transmission malfunction that needs servicing.
- Delayed engagement occurs when you shift from Park into Drive or Reverse; there is a significant delay before the gear engages, often accompanied by a clunk.
- Unusual noises, such as whining, humming, or buzzing that change pitch with the engine’s RPM, indicate low fluid or a failing torque converter that needs servicing.
- The “Transmission Fault” warning light is triggered when the vehicle’s OBD system detects irregularities in the system, indicating the need for diagnosis and service.
- If you notice reddish-brown or dark-brown fluid spots under the Jaguar, it’s a clear sign of a transmission leak that needs to be addressed.
Transmission Service Procedure
A complete transmission service includes the following steps:
- Diagnostic Scan: Our technician in Green Bay first scans the Transmission Control Module (TCM) for any registered fault codes and identifies underlying issues.
- Cleaning and Inspection: Here, the transmission housing mating surface is cleaned and inspected for any signs of leaks or damage to seals and connectors.
- Fluid Drain: The old transmission fluid is completely drained and inspected for color, smell, and the presence of excessive metal shavings.
- Pan and Filter Replacement: On ZF 8-speed Jaguar transmissions, the entire pan assembly, including the filter, is replaced to resolve a clogged filter.
- Fluid Refill: Jaguar specified transmission fluid, such as ZF Lifeguard Fluid 8, is used, and the system is refilled to the appropriate level.
- Precise Temperature-Controlled Filling Procedure: A temperature-specific refilling process is adopted, in which the engine is started and fluid is pumped into the transmission to a specific level. The technician then cycles the transmission through all the gears while monitoring the fluid temperature. The final fluid level is set within a particular range to ensure it is neither over- nor under-filled.
- Software Adaptation Reset: In the end, the diagnostic tool is used to reset the system, ensuring optimal performance with fresh, clean fluid.
