Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Suggestion
I believe this design was more robust, had one of the microswitches in one of the transmissions and could replace the original transmission in earlier cars.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I was able to source what I think is a pair of good transmissions from an '10 boxster and all the associated equipment (cables, lifting arms, tonneau shocks) apart from the motor and the mounting pins for the body. I have done some google research and some people say there is a transmission upgrade but I was not sure whether they were referring to the later 987 setup or some kind of upgraded 986 specific parts. From what I gathered it may be possible to swap the two but I read somewhere that you need the mounting pins that connect the transmission to the body as they are different or upgraded? Is there anything else I am needing? I rebuilt my transmission gears last year but never could get it synced correctly with the top (ball pivots kept popping off even after replacement). If this is a relatively simple swap I may give it a try and sell my spare 986 stuff.

POST 2Original post

Cannot answer your question regarding transmission, but maybe worth checking that before. They explicitly name the problem that, despite the setting, the heads always come off, from minute 12:00 onward. https://youtu.be/vfqFzFs3bmU

POST 3Original post

I believe they updated the convertible top transmissions in 2003 when they went to a glass rear window. I believe this design was more robust, had one of the microswitches in one of the transmissions and could replace the original transmission in earlier cars. I'm not sure about using 987 transmissions in a 986.

This is a source reference. Confirm exact model applicability in the original material.
