Porsche 911 3.2 New Shift Knob

 Some pictures of a new knob I bought from Moore Knobs.

Speed Sensor Replacement

My 911 could not start. Both alternator and fluid pump were working fine. Using the diagnostic method below I found out the resistances were zero. 911 3.2 engine requires both Speed and Reference sensors to work to start the engine.

Speed and Reference sensor connector locations and diagnostic method.

Sensor with harness part numbers. Other part numbers -91160621501

91160621500 - this is an old number
ref. 026121002 and cross reference 12141708619 m14

Sensor positions and gaps between the sensors and the crankshaft.

Porsche 911 3.2 - Transmission Fluid Change Out

This is to show some experience I went through during the fluid change out. 

First transmission drain and fill plugs part number. They both are the same plug. 

Drain plug captured some metal shavings. Not a good sign. The plug on the left is new.
