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.

POST 1 / ORIGINAL POSTEROriginal post

I have 2000 996 Tiptronic. When I drive it, the Drive and 4th gear lights start blinking, and it looks like it stay ate 4th gear. However, when I let engine warm up, and restart the car, this problem goes away. It happended 3 times, and one time check engine light came up also. My mechanic couldn't find the problem, they resetted the error code. Error code was referring to changing selonoids in the transmission. However, given the problem is not repeatable and happens when engine and outside is cold, I am suspecting transmission fluid, or some other faulty mechanism. It looks like transmission fluid is dirty, but I have checked the service manual it does not require transmisison service until 60K miles, currently is at 43K miles. Any idea? Thanks!

POST 2Original post

That's the limp mode when your gear sticks at 4th. That's default gear when there's a problem with the transmission. I would take that as an early warning of something to come, especially when the transmission is concerned, it's NOT cheap at all. If you're lucky, it might end up being just a gear selector switch module. Maybe you should have the dealer check it out.

POST 3Original post

whjat fault codes were in the dme and tip ecu ?

POST 4 / ORIGINAL POSTEROriginal post

Thanks for the replies! 70 (OBD II code P0740) 92 (OBD II code P0717)

POST 5 / ORIGINAL POSTEROriginal post

This is just a follow-up. I took the car to dealer, it was caused by faulty speed sensor. $1200 is the cost of changing it at dealer.

POST 6Original post

I thought tips were serviced at 90k?
