Tiptronic P1818 and P1823 - 986 won't shift into any gears

Durometric pulled Tiptronic P1818 and P1823 codes after I was unable to shift into any gear on my Boxster.

There has never been any issues whatsoever with the transmission.

However, while parking my car the previous night, I accidently turned off the car while in Drive.

 

- At the dash with engine started, the dash correctly displays proper gear to match the shift lever, but the car does not budge.

- The mechanical linkage at the rear is all connected. 

- I checked fluid level and and some fluid did come out at the fill area but the fluid is very dark with NO burnt smell.

- I reset the Tiptronic fault codes and later disconnected the battery for 30+ minutes to no avail.

--- Also, odd thing is that the Tiptronic fault codes no longer return after reset.  They show green state.

 

My local shop says they don't work on Tiptronics.

 

I read I can R&R the ATF and Filter and I am considering that myself.

However, I need a plan of attack.  I live in Riverside County California.

 

Please advise. Thanks.

Thank you for these guides. Based on what is observed it refers me now to Chapter 11 (0-142).  Is this information available?

 

Odd thing is that after clearing the transmission fault codes, they have not yet reappeared. I will go through the steps here and I may also try to remove and replace the filter and ATF this weekend.
 

 I’m also looking for a local mechanic as my regular place does not work on Tiptronic transmissions.
