Some of you may recall a while back about me having odd shifting issues with my car between 1st-2nd gear. I ended up having a local shop fix the OSS
since I couldn't do it in my garage due to bad exhaust manifold posts that would've broken off had I have attempted to remove the bolts. Immediately after I got my car back it was making a really wierd noise... like I had some kind of failed whipple supercharger on my car. The whine it'd make as I idled was bad... when I gave it acceleration it was enough for guys driving ricers to give me really odd looks like, "wow, man I want that!" Anyway... ruled out the belts by removing it from crank pulley. Noise was still there. I wasn't getting any codes or having any issues so I drove on it for about 2 months, just locally to school and work mostly. Then last week on the way home I got a new symptom when I slowed down to go over some railroad tracks: car began to buck and would not lock well into 2nd, 3rd, or 4th gears. Two more tests later confirmed that this happens about 2-3 minutes after the car warms up. Took my car out for a test last friday cause a friend wanted to see what it does... and we nearly broke down. Soon as I stopped in the driveway, we popped the hood and gave it a bit of gas- car dies. Restart, and retry- car dies again. This time a CEL
comes on and I scanned it as PO320- CPK cricuit malfunction.
So saturday I looked that thing up, found it on my car. Went to pull it out and it was essentially snapped in half! I don't know or how my car was even functioning at all! It was dragging on the flywheel and making that whining sound. It was also sending faulty PIP
signals which was killing my car stone dead. I replaced it... noise gone, car runs good as new. Perfectly smooth shifts. I even reset the PCM
so it'd relearn the shift points. So on 50 mile learn mode now... and I have one heck of a souvenir! See attachments to see my mangled CPK.
Only thing I can figure... this part did not and could not have broken itself. It's impossible. I tried to snap the cam sensor in half and there's just no way (yes, I replaced both sensors). What must have happened is that the transmission shop that did my OSS
tried to remove the wrong sensor (the CPK) by ripping it out with pliers without rotating the alternator like you're supposed to. I had tons of issues with that shop, btw, called them out as soon as I got the car back, and it nearly came to a violent confrontation. But I know what they did, and I left them several horribly wonderful reviews online complete with the CPK pic.
2 months of hassle... and all they had to do was tell me they messed up. Unbelievable. Anyway... I fixed it. Here I was about ready to write my old bull off, but seems she still has life afterall!
