Put new GPS in place of the original GPS that was failing intermittently.
For three days the GPS would fail and my tranny would go to default: Gears 2.5, and 6 and R only. I drove the car like that for a few days and the GPS would decide to work again and the SMG would work like it did in 2002. Just fine...until the GPS would go out five days later.
At the time we replaced the GPS(two weeks ago) it was in one of its brief operational modes. SMG was fine, but the periods of time the GPS would not work were getting greater. Cog was almost always lighted even if the GPS was working fine. Once in a while the GOG would go away for 12 hours. Then come back.
Now, I have a car with ZERO gears. N only.
We went from a working SMG (sort of) and perfect running car to one that will not go or show any gear but Neutral.
INPA gear adaptations would always quickly FAIL. I would disconnect the battery in between attempts in order to start with a freshly reset tranny.
It seemed that the SMG pump, valves and solenoids PASSED. Plenty of pressure. I always had no issues with that. INPA shows 85 or 87 bar.
I was highly urged by some members here to install a new roller detent and two detent springs. On advice we also replaced a temp sensor and a crank speed sensor.
On this realoem diagram we replaced parts 5,6,7 and 9. Note part #7, the roller detent. I have a question about that. My helper just inserted it with out any orientation at all. Does that detent NEED to be inserted in a specific orientation??? ie roller portion parallel to the drive shaft or perpendicular?

On this next diagram we replaced parts 10 (crank speed sensor) and 13 (Temperature sensor coolant / oil). and part 2 (the Gear identification switch AKA GPS)
I double checked the GPS shaft end. It is oriented perfectly with a little bit of fresh grease. That IS important.
I even purchased another GPS just in case the first one was faulty. Both came from reliable suppliers. I believe they BOTH are working properly....but car no workee. No tranny gears!!! Just in case I took out the newly inst3alled used GPS and installed another LOW mileage GPS (75K miles) off an SMG tranny throwing NO codes at the tome of removal from the donor car.
I checked all the PINS in the electrical connectors. Clean and FINE. No issues.
I can only think of two things:
1) The part#9 roller detent is not oriented correctly.
2) My IPNA just isnt cutting it. I have heard GT1 software coming to the rescue.
My DIS/GT1 from BC cables it supposed to work on Win 10. It does NOT!!
I tried BC Cables INPA AND Mikes Tools INPA. They seem to be 100% identical. I get the same results from both of them. A HUGE FAIL on gear adaptions.
We did tilt the tranny down 10 degrees to get access to everything. But we always had it bolted back in place PARALLEL with the ground....within 2 degrees or so.since the gar is on a tiny tiny bit of a slope. Only a couple degrees off level. The car is on giant 6 ton jack stands. Do I need to take a freaking LEVEL and SHIM my rear jack stands? I cant believe a few degrees off level would mess up gear adaptions.
Where can I get a copy of GT1 that will work with Win 10??
