P0701 Pd code. Tiptonic problem
On the way home from autocross on Sunday just motoring along on the highway the tip transmission acted up. When i shifted from third to forth it started slipping on the third time from third to forth .... No forth , like it was in neutral, shifted to fifth, no fifth like in neutral ... At this time there are no lights on the gear position indicators . It would not engage in any gear and I cost to the side of the road. After I stoped I shifted into park than back into first gear and it engaged . This time forth gear was not there like it was neutral and made it info fifth and it engaged. I made it home. On the way up the driveway it stayed in third and I parked it. I checked codes and p0701 Pd was there. Anyone have anything similar or thoughts.

Maby it's not too bad. Looks like it's more likely an electrical problem.

P0701 is not enough of a code , you also need the number ie 15, 49 ,51 etc . To read out codes fully and reset them you will need a PST2 or durametric to reset the Tip Codes
From the workshop manual. Hope its all copied correctly .
P0701
15 Excessive speed n2 or n3
A check is carried out to ascertain whether the n2 sensor signal or
the n3 sensor signal exceed a limit value. The aim of the fault detection
is to detect a hydraulic or mechanical malfunction of the transmission.
The frictional connection is interrupted by the Tiptronic control module!

Checks are carried out to ascertain whether a gear is implausible or
the transmission slips.
The redundancy transistor is switched off. The setpoint values of
the current regulator are set to 0 and all change-over valves are
switched off. The control module is then in emergency operation.
Minimal cycle is additionally activated.

roger that. i wanted to make sure there were no codes that could be stored to keep it in say limp mode after a battery disconnect. the 701 code gives a lot of stuff that could be wrong. tonight i am going to take the pan off and see if this adds any info to a problem.

This is not quite correct. While some codes will clear with soft reset (disconnecting the battery) others will not. Some will also clear with cycles (on/off) and others will not.

if there are some codes that cant be cleared with battery disconnect how are they cleared. i have a code reader and a flash cable , but not duramatic software. what ever i need to get i will get.
