Hi Mazda Protege5 people!
Okay, my Transmission is slipping into 2nd/3rd gear and the O/D light is blinking as well. I think this "downshifting" symptom is a safety measure brought on by the fact that the Pulse Generator is failing. My cheap OBII is not pulling any codes.
I also found a video online that basically shows my issue (although, my P5 is an automatic with ABS). The youtube link is below:

UPDATE AFTER REPLACING THE PULSE GENERATOR:
- I was NOT able to resolve the above issue by replacing the Pulse Generator. This is the term used in the repair manual for the part I replaced today: FN0121550 (Automatic with ABS part number).
- The car will NOT go into Reverse now and it makes a loud clunk when I shut the engine off.
- The O/D light stopped flashing but that's probably because I didn't drive it long enough.
- For my own knowledge, are these terms equal to "Pulse Generator"?
1.) Vehicle Speed Sensor (VSS)
2.) Turbine Speed Sensor
3.) Input Speed Sensor (ISS)
4.) Throttle Position Sensor
5.) Crankshaft Position Sensor
- I've seen these terms tossed out there and according to the P5 manual, the part I'm dealing with is only called a Pulse Generator.
- I've fully confirmed that the Pulse Generator part # is FN0121550 and if you put this number into Amazon.com, you'll get Beck/Arnley 090-5047--WHICH IS INCORRECT. I ordered 090-5047 and it's a three-prong and absolutely not the Pulse Generator FN0121550.
- I removed the air intake system and NOT the battery + tray. From there, it was pretty easy to get to. CAVEAT: Be careful not to get any dirt in the sensor hole/insert.
Also, I have 266K miles and think it's probably time to change the transmission fluid. Or is it?
- Is this okay to do on a car this old? Someone told me that the car has "developed" its own tranny fluid viscosity/consistency and that fresh/new transmission fluid could completely send it to hell. Is that true? Sounds odd but logical, too.
Please address my questions.
Thank you.
