I've searched, and read..but still uncertain, hence this thread.
2002 V8 LSE. 88k miles. Had car since new. Transmission fluid flushed by dealer at approx 75k miles. Valve cover gasket and plugs replaced around 64k. No current oil leaks, and in general, car runs great.
Approx 4 weeks ago, while accelerating briskly at about 40mph, engine stumbles briefly. Goes from 4500+, to a quick rpm drop to about 2k, then right back to normal acceleration. No CEL lights, no warning lights at all.
3 days later, same thing. A week later, when pulling off from a light, same thing.
This morning when attempting to make it through a yellow from about 40mph, I floor it..immediate hesitation, jerk, stumble, then "Check Transmission" appeared on the display. Car then accelerated as normal. D5 still remained on the gear selection display. No "E" error code there. Within about 30 seconds, the "Check Transmission" disappeared, and car appeared to drive normally. Hit the "status" button to see if any errors were in place, and there were none. Turned car off in garage, restarted, and no codes. Haven't had a chance to drive it out of garage yet.
With the above symptoms in mind, am I looking at a failing COP, or a transmission valvebody/solenoid issue, or a combination?
Is this something I need to take in NOW as a preventative measure, or do I wait on this.
