There is so much wrong with this approach I don't know where to begin. Agreed, a trip to the dealer MAY sort this out, but I would hold onto your wallet. The key, immobilzer and DME/ECU must all be programmed with the same codes only Porsche Stuttgart can provide, to a licensed Porsche dealer with PIWIs. What you have done is replace parts with other parts and expect them to work. It doesn't work like that. Key provides both the mechanical laser cut key blade that works the electro-mechanical parts of the door locks and key switch, BUT, also includes an passive RFID pill that must match the key code programmed into the immobilzer. The key RFID pill is read when the key is inserted into the ignition switch by the ignition switch surround. The pill must match the immobilzer key codes. If it is correct, the immobilzer communicates a go (or no go) to the DME/ECU. All must be programmed the same. The codes in each must all match or the car will not start. You are looking at least at several hundreds of dollars at a Porsche dealer for programming. If the keys, immobilzer and DME/ECU need to be replaced, several thousands of dollars...at a Porsche dealer. And bonus, the immobilzer can only be reprogrammed a limited number of times, then it must be replaced. Walk very carefully on this one. Remember, this is a security feature of our cars so they cannot be stolen, and only the Porsche factory in Stuttgart will provide the codes to a licensed Porsche dealer. Good luck.1 point

Thank you, really appreciate your help! Sorry for the late update but I fixed it. Transmission shifts perfectly now. At first I could not find this green solenoid anywhere. A black one which is right next to it is totally similar to shift solenoid from another AISIN transmissions used in VW / Jetta. I bought it and tried in place of green one. Bad decision! Transmission was out of limp mode but shifted really badly, with big delays going to each gear. I finally found a whole assembled valvebody with all solenoids from broken transmission parting out, replaced both black and green from it to my transmission and everything is perfect! It shifts better then new. For the laughs, here lessons learned: - Transmission oil/filter change can be done in 30 minutes on jackstands on a driveway if you did it 3+ times lol - Substitution of solenoids for another part is bad idea - Most transmission filters that you can buy come from who knows where, despite proper markings. First new filter that just came in had a neck smaller (just tiny bit) then old one. And even with new rubber gasket wont seal properly with valvebody. Next, different source filter was perfect. - Schwaben brake bleeder / fluid pump is worth it's price in gold. Just get it if you want to fill transmission in minutes with no mess. Thank you so much everyone who helped, really appreciate it!!!1 point
