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.

I physically checked out the tcm. All seamed fine. Everything was tight. I disconnected all and reconnected.

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!
Diagnosis conditions



Ignition on



n2 > 7000 rpm or n3 > 7000 rpm

Possible fault cause


Mechanical fault in the front planetary gears



Excessive speed sensor n3 or outer disk bracket faulty

Affected terminals
-
Diagnosis/Troubleshooting
49 Excessive speed engine
The CAN engine speed signal is checked to ascertain whether a
limit value is exceeded. 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

Diagnosis conditions


Ignition on



Engine speed > maximum switch speed + offset (e.g. max.


switch speed = 6000 rpm, offset = 500 rpm)

Possible fault cause


Mechanical fault in the front planetary gears

Affected terminals
-
Diagnosis/Troubleshooting
50 Impermissible transmission ratio
The transmission is checked to ascertain whether it shifts down as
permissible.
The frictional connection is interrupted by the Tiptronic control module!
Diagnosis conditions


Ignition on

Possible fault cause


Mechanical fault in the front planetary gears

Affected terminals
-
Diagnosis/Troubleshooting
Work instruction Display OK If not OK
1 Disassemble transmission and repair according to findings


End

Note!
Work instruction Display OK If not OK

1 Disassemble transmission and repair according to findings End

51 Transmission slips or gear implausible
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.
Diagnosis conditions


Ignition on



No active gearshift



No speed n2 fault



Engine speed n2 > 150 rpm



No selector lever fault



No CAN fault



No PSM fault



At least one plausible rear wheel speed



All plausible PSM wheel speeds > 50 rpm



Difference between right and left wheel speed < 100 rpm (rear


and front)



Output shaft speed > 180 rpm



Engine speed > 450 rpm

Possible fault cause


Leak in hydraulic wiring



Leak in mechanical transmission parts



Oil filter missing

Affected terminals
-
Diagnosis/Troubleshooting
Note!
Work instruction Display OK If not OK

1 Disassemble transmission and repair according to findings End

All the codes should clear with the battery disconnected for long enough, but that doesn't mean they won't come back.

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.
