Old thread...the fix to my problem has been identified! <img src="/forums/images/graemlins/notooth.gif" alt="" />

Just last week I had the transmission throw a SES code (P0720 Output speed sensor malfunction IIRC), shift irratically, and the "N" light was flashing on the dash. All this happened and I got home in fail safe (3rd gear). Well it sat for the weekend, and I got it to the dealer dreading what they would tell me...

Well there was a "broken" power wire to the output speed sensor. <img src="/forums/images/graemlins/confused.gif" alt="" /> $300 to get to the wire and solder it. The tranny is fine now, and I decided to throw it in 4-H for shits and giggles and the system worked like it was brand new! The light blinks for two seconds, and stays solid like it is supposed to! WAHOO! No more flickering! <img src="/forums/images/graemlins/kewl.gif" alt="" />

Just thought I would post this up...in case it is helpful to others. The issue I had was NOT a "blinking" 4-H light, but it flickered like it wasn't getting power to stay solid. In the end, I guess it wasn't.
