[Ronnie38]

MY2001 911C4 CAB : Had slippage in 3rd when making a 90 degree turn as it shifted into 3 underpower. Ah I though low fluid so I changed the filter and the oil yes Porsche type. Now if I drove it right (go like a Porsche) and so 3, 4th then flashing indicator and limp mode. Took it to an Indy Porsche mechanic, replaced valve body input output sensors, worked on it for 3 months gave back no charge couldn't fix it. So I have been driving it in manual shifting at 2200 RPM works fine if I go to 2700 RPM bingo limp mode. The P0717 just; showed up today as I pushed it.

The P0717 on line checking said the control module or ground fault. Anyone out there can help? Don't want to throw money at it and buy a control module.

thanks for the info. It's 60 miles to the nearest dealer, so I was trying to fix it myself, will ohm out the wiring then try controller then change the clutch packs.

Did the mechanic do the ATF fill correctly? Did he/she use a thermometer to make sure it was full at the proper temperature?

[Ronnie38]

yes we did, level at temp after fill to top off and still running when plug installed 4 times once to change filter, then replacing speed sensors, replace valve body then recheck after test run.
