Well, I’ve looked all over the place for information but nothing very specific about my issue has come up. My S3 light started coming on during a trip, and the car began shifting erratically at times (maybe 10% of the time), also routinely shifting at largely different RPMs than normal, and whenever the light is on, the car refuses to shift to 4th gear. So, I found code 9 below the dash which is the A/T speed pulser, and that’s it. The fluid looks healthy, clean and red. My question: do the symptoms match the code? If I replace the A/T pulser, will my problem be solved or will my gears fall apart anyway?
The code doesn’t seem like the end of the tranny problems to me. I’ve also been having speedometer issues for a long time, since last year when I had the VSS and cable replaced. This may be related but I don’t know how. Now the needle sticks quite a bit (roughly every 5 mph on the gauge), but generally works. I also had a ticking noise coming from behind the firewall I think, which was related to the speedo problem, and it doesn’t seem to be happening now that the A/T pulser is giving me a code.
I’m about at my wits end with this POS! I’ve spent too much money in the last year alone fixing it, and I won’t bother fixing the tranny too if it’s surely dead. Any insight is much appreciated!
