Tiptronic S Rebuild

[lebow71]

I have just had the 90,000 mile transmission service on my 2001 Boxster 2.7 tiptronic. Mechanic found metal shavings in the pan and was suggesting there may not be much life left in the transmission. Has anyone rebuilt a tiptronic S transmission or can recommend a reputable rebuilder in US or Canada and what a reasonable cost would be to expect?

thanks

It's common to find metal bits in the oil pan but how much and of what material is what's important. If you're not having any transmission problems I wouldn't worry about it and keep driving until things start to go south.

not sure what material the metal shavings are or from exactly but here is a photo. Car is shifting better since the fluid change but under high torque and low rpm's (usually going up a steep hill) I have had instances of a shudder. Other times it will sound like it down shifts and the rpms go up however it stays in the same gear. It doesn't feel like there is much slipping at the moment.

If that is all of them then I would not worry as that looks normal for a 90,000 mile change.

Play it by ear but you might have a steel sealing ring or two failing and if that's the case then the slipping/RPM flare up or gear fall out will increase over time. I would also check the conditions of the engine/transaxle mounts which can increase drive live angles and cause vibrations under loading. Are there any fault codes?

The Codes that were scanned are as followed:

P1133 oxygen sensing adaptation- lower load range bank 2

P0107 ambient pressure sensor

P0102 Hot film maf sensor

P1128 Oxygen Sensing adaptation idle range bank 1

-22 Load Signal, DME Control Unit(Transmission Fault)

Alarm Codes

-33 Passenger Compartment monitor Sensor

-47 Control Locking Synchronization

-61 Central Locking Limit Position Unlock Not Reached

Airbag Faults

-3 Power Supply

-195 Unknown DTC

-102 Unknown DTC

I have since replaced the MAF sensor and the car is running much better and the CEL is staying off. I still experience some "shudder" when going uphill under load. Have not had a chance yet to inspect the engine or transmission mounts...

Clear all codes and monitor which return.

Interesting that my '99 996 also does the shudder under the same conditions especially when going up hill. However, there is no flare of rev or slipping. It also only seems to happen as the car is warming up but once fully warm, it doesn't recur until I restart the car. Even when warm when i restart, it will happen once or twice then all is normal again.

The fluid change with Esso LT 71141 ATF and MAF change helped.
