D-4 lights flashing but normal shifting?
Lately my 2001 Boxster S tiptronic has been throwing a P0710 code. This is indicated first by my transmission selector lights flashing alternately between D and 4. Otherwise the transmission behaves normally, shifting up and down, in both auto and manual modes (not in "limp mode"). Information on this is sketchy. My durametric tells me that the code (P0710) is a Transmission temperature sensor fault. I would first like to check the sensor, a procedure which is briefly outlined in a repair manual ("Check sender for ATF temperature with wiring. To do this connect an ohmmeter to control module connector pins 21 and 22...etc.) Now there's a box in my rear trunk that's supposed to be the control unit but where exactly are the connector pins 21 and 22 located? Sorry if I seem a bit dense here. :unsure:
Seems that the fluid is okay. It was replaced in the spring. It may be the sensor. Had a hard time finding the right part number. Apparently you have to replace the whole wiring harness. The part is 4 hundred and change at Porsche, I found an OEM for 170. I'll try to figure out the electrical troubleshooting procedure first. I dropped the aluminum shield to try to get a look but I'm still not sure where the damned this is!  Any input would be appreciated!

On my Porsche system 2 tester I am able to get a temperature reading in drive or reverse for my trans.. You do the same on your meter to see how it is behaving when you trans is cold and hot just to get a base line of what going on before you spend any money. To check you fluid level the transmission temp has to be between 86-100 F. That is if you sensor is reading correctly.

Seems odd: I can't seem to find a temp reading for the trans on my durametric. I get motor, engine compartment, oil, air intake, but no transmission fluid temp. I guess I can buy an infrared temp guage.

Yeah, just called Durametric. Not supported for the 886,
 Apparently ATF temp may be aailable on newer cars. |

Did you say 2001 Boxster? I'm not sure about the Durametric on my Porsche tester I am able to get a temperature reading for the transmission.

Well, I guess your tester's better than my tester!
 But then mine was only $287.
