What This Product Does

This gearbox forms part of the convertible-top drive assembly. It transfers drive through the roof mechanism to operate the folding top; it is not the vehicle’s main transmission.

Functions

• Transfers drive within the convertible roof assembly.
• Works with the associated shafts, levers and rods to move the roof mechanism.

Technical Details

• Brand: Porsche.
• 98756117903: left-hand transmission.
• 98756118003: right-hand transmission.
• Both references carry the supplied production identifiers F 986U7 02823>> and F 986U7 22146>>.
• The diagrams also identify drive shafts, rods, levers and other associated components; these are separate parts, not descriptions of this transmission.

Symptoms of Fault

A noisy, slow or non-operating roof mechanism warrants inspection. These symptoms alone do not establish that the transmission requires replacement.

Why Replacement Matters

The convertible roof transmission contains internal drive components that operate whenever the soft top is raised or lowered.

With age and repeated use, internal gears or drive components can become worn or damaged. A seized or faulty transmission can prevent the convertible roof from operating correctly and may cause uneven movement between the two sides.

Replacing the affected transmission helps restore the correct mechanical drive to the roof mechanism.

FAQs
