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.

  • Pelican Parts: 1 discussions

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 3Original post

Car is a 15 911S. First you have to find the fill plug. Then the proper drain plug. It's a big secret at the dealership. There's two fluids in the box, so I'm told. The gear oil, and the ATF oil. You don't want to mix up by accident. Tragedy will ensue. Next is the refill method. Pat your head, rub your tummy, heat the fluid to a temp, dip your finger. I'd say on the ATF, capture what comes out and refill that exact amount. You may have to do it a couple times since it all doesn't drain when you pull the plug. On the gear lube, just put back what you take out, once. I've had the dealer do the ATF at 40,000 and 80,000 miles. At 120,000 I'll have them do both.

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