2012 Bentley Continental Supersports Convertible Transmission

Delayed engagement, slipping, shudder, harsh or erratic shifts, or a transmission warning light indicate the vehicle needs diagnosis and likely service.

Fluid issues, adaptation changes, or mechanical wear can all produce similar symptoms, so inspection—not guesswork—determines the next step. A scan for codes and a fluid condition check are the fastest ways to separate a simple service from a developing fault.

• Delayed or harsh Park-to-Drive engagement
• RPM flare or shudder on upshifts
• Burnt-smelling, discolored, or contaminated fluid

Identification of the fitted transmission, correct manufacturer-specified fluid, fluid level/condition check, code scan, and pan-and-filter service where the design allows.

After service, the transmission is filled using the factory procedure and set to level at the specified temperature, then road-tested to verify shift quality. Recommendations are confirmed from the vehicle, not assumed from the model name.

• Use of the fluid the manufacturer specifies
• Factory fill/level procedure at precise temperature
• Road test to verify smooth operation

The manufacturer publishes the schedule for this vehicle; most list Normal and Severe intervals, and fluid condition can be inspected between them.

Driving that includes towing, heat, steep grades, or stop‑and‑go places a vehicle on the Severe schedule. In Greater Boston traffic, a periodic condition check is prudent, especially if shift feel changes.

• Follow the published schedule for the fitted transmission
• Severe use shortens service intervals
• Inspection bridges the gap between mileages

The correct fluid is the one the manufacturer specifies for the exact transmission installed, and it is not interchangeable with universal fluids.

Using the wrong fluid can damage the unit. The fluid is identified from the vehicle (VIN/parts data and transmission tag), not from the model name alone. Service verifies this before filling.

• Confirm from the vehicle’s build and transmission ID
• Use only manufacturer-specified fluid
• Avoid universal or mix-and-match fluids

A drain-and-fill replaces roughly the pan volume; an exchange refreshes more of the system—condition and service history decide which is appropriate.

Fresh, serviceable fluid may only need a drain-and-fill with a filter where applicable. Heavily degraded or contaminated fluid may justify a more complete exchange. The shop inspects first and then recommends.

• Evaluate fluid color, odor, and debris
• Review prior service records if available
• Select the least invasive option that meets the need

Driving on a slipping or harsh-shifting transmission can turn a serviceable condition into a repair or rebuild—book a diagnosis immediately.

Some symptoms are caused by fluid condition, but others indicate clutch or mechanical wear. Early inspection limits damage and preserves the chance that fluid and filter service will help.

• Stop aggressive driving and heavy loads
• Schedule service for diagnosis
• Document symptoms and when they occur

Some transmissions are built without a dipstick or routine interval; whether this vehicle’s unit is one is confirmed from the vehicle itself.

Even on “sealed” designs, fluid condition and leaks can be inspected, and level can be set at temperature using factory tooling. Service recommendations follow inspection rather than assumption.

• Confirm design and procedure from the vehicle
• Inspect fluid condition and leaks
• Service only with the specified fluid

An independent shop may be less on labor and fluid; the dealer stocks the specified fluid and follows the factory procedure for this transmission.

Bentley Boston offers OEM parts, specialized diagnostics, temperature-based level setting, and a documented road test. Choose the option that matches the vehicle’s needs and your preferences.

• Dealer: specified fluid and factory fill/level
• Independent: potential labor/fluid savings
• Both should inspect first, then recommend
