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.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

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

  • Planet-9: 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 1Original post

I am experience a surging between 1500 and 2500 rpms. It is worse going uphill, but does not do it above or below. It also does this in all gears. While parked the idling is good. Here is what the Porsche mechanic said. He said the main line pressure for transmission fluid control loses pressure on and off which is a sign of a weak solenoid. He suggests to replace transmission ( I can't afford!) also, he says I can replace valve body or individual solenoids. Does this sound right? 1. He did a 89757 internal malfunction test with piwis tester - none registered. 2. fluid level - good. 3. tested MAF - good 4. tested for power and ground on TCM module - good 5. removed torque converter lock up wire and test drove- good 6. checked fuel pressure - good 7. no codes in vehicle 8. solenoid circuits are intact and complete 9. Tiptronic test - No codes Diagnoses: He said the main line pressure was checked with a piwis tester and it it showed the main line for transmission fluid control loses pressure on and off which is a sign of a weak solenoid. Is this possible, anyone experience this, and what is the cost of a repair? I am a at loss. I need help!
