2012 Bentley Continental Flying Spur Transmission

Delayed or harsh shifts, slipping, shudder, or dark/burnt-smelling fluid indicate it’s time to book a transmission inspection.

Symptoms point to a need for diagnosis, not a guaranteed fluid-and-filter fix. An inspection checks fluid condition and level, looks for stored fault codes, and verifies adaptation values before recommending service.

• Delayed engagement when selecting Drive or Reverse
• Noticeable flare, shudder, or harsh upshifts/downshifts
• Dark, burned, or contaminated transmission fluid

It includes fluid condition/level checks, electronic diagnostics, manufacturer-specified fluid, and pan/filter service where the design allows.

The technician confirms the exact transmission from the vehicle, follows the factory fill and temperature procedure, and road tests to verify shift quality.

• Scan for stored transmission fault codes and data
• Drain, pan and filter service if applicable, gasket replacement
• Refill with the specified fluid and temperature-set level

The manufacturer publishes a schedule for this vehicle; service timing depends on that schedule, usage, and fluid condition.

Most manufacturers publish normal and severe schedules—towing, heat, and stop-and-go driving put a car on the severe one. Fluid condition can be inspected between intervals to guide timing.

• Follow the manufacturer’s maintenance schedule
• Adjust for severe use: congestion, grades, temperature
• Confirm with a fluid condition inspection

The correct fluid is the one the manufacturer specifies for the exact transmission installed, identified from the vehicle.

These fluids are not interchangeable, and using the wrong one can cause damage. The shop verifies the transmission variant and fills only with the specified fluid.

• Identify the transmission from the vehicle, not the model name
• Use only the manufacturer-specified fluid
• Set final level at the specified temperature

Condition and service history decide: a drain-and-fill replaces pan volume; an exchange refreshes more of the system.

The shop inspects fluid and checks history before recommending an approach. The goal is to protect the unit, not default to the most extensive service.

• Inspect fluid color, odor, and contamination
• Review service records and stored transmission data
• Select the method that best fits condition and risk

Driving on a slipping or harsh-shifting transmission can turn a service into a rebuild—book a diagnosis promptly.

Slipping, shudder, and harsh shifts may indicate wear or hydraulic issues. An inspection can determine whether fluid, adaptation, or internal faults are involved.

• Schedule diagnostic testing before further driving
• Verify fluid level/condition and scan for codes
• Prevent added heat and clutch wear

Some units are built without a dipstick or routine interval; inspection and a fluid condition check still guide care.

Whether this vehicle’s transmission is one of them is confirmed from the vehicle. Even sealed designs require correct temperature-based level checks and may need service based on condition.

• Confirm transmission design from the vehicle
• Inspect fluid condition and check for stored codes
• Set level at specified temperature if service is performed

An independent may cost less for labor, while the dealer stocks the specified fluid and follows the factory procedure.

Choose based on capability and parts. Bentley Boston performs temperature-based level sets, uses manufacturer-specified fluid, and completes a verification road test.

• Compare tooling, training, and access to service data
• Confirm fluid type and fill/level procedure
• Ask for a post-service road test and report
