Replacing TIP inhibitor switch

[mikesz]

Has anyone replaced an inhibitor switch on a 986 tip car? I have a 99 tip and the "M" mode doesn't work. the thumb switches on the steering wheel do not work at all. So I bought an inhibitor switch and got underneath the car to see how to replace it and it looks pretty ugly.Looking for info/advice procedure on how to do it. I can see it when I get underneath the car but lots of "stuff" in the way and don't want to do this without some research beforehand!

Do you mean the multi-function switch on the side of the transmission?

Yes that is what I am talking about "1" in the photo above. It looks very easy in the picture 2 bolts but reality is much different and I wont even attempt it without doing some serious research.

There are some cooler lines and what not in the way, but it is not that bad a job.

The following procedure is for Boxster only.

Removing and installing multi-function switch

 

Removal

1. Hold engine by transport shackle in installed position with special tools 10 -222A and 9591/1

 

 

2. Remove the left catalytic converter.

3. Detach selector lever cable from deflection lever and transmission support.

 

 

4. Place transmission jack under the transmission.

5. Remove the left transmission support with hydraulic mount.

 

Note:

The fastening nut M12 © must not be loosened. The transmission support will otherwise be damaged.

 

 

A -Transmission support

B -Hydraulic mount

C -fastening nut M12

6. Release and disconnect cable connection to multi-function switch.

 

7. Unscrew fastening screws and pull switch off the selector shaft.

 

 

 

Installation

Install in the reverse order.

 

Put multi-function switch on the selector shaft. The flat point on the serrations in the switch (3) must lie against the flat point on the selector shaft (1).

 

 

Note:

Place multi-function switch on the selector shaft. Do not tilt or use force: you may damage the switch contacts.

2. Turn switch until the fitting bore (4) can be put on the dowel pin (2) on the transmission housing.

 

 

Tightening torques

Multi-functions witch to transmission housing -- (M6) = 8 Nm (6 ftlb.)

Transmission prop to transmission housing -- (MID) = 65 Nm (48 ftlb.)

Hydraulic mount to carrier side section -- (M8) = 23 Nm (17 ftlb.)

This info is just what I was looking for. Thank You, Loren and JFP! I think I will put this on my spring projects list. I live in RI and its getting cold. Time to put the baby away.
