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.
|
Has anyone ever had a tcm go out.
|
looks like your on your on. I do not mess with tips. So I dont have any input for you.
|
Thanks for at least a shout, it's been me myself and I on this one.
|
I'm sorry I don't know TIPS, but problems with automatics is dirty filters / fluids. Just a guess. Good Luck.
|
I will keep posting on this as it gets figured.
|
does anybody know if there are any codes that can not be cleared by disconnecting the battery..

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.

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.
