Good Morning to the SCCOA Forum.
I am going into serious depression. I bought this 1992 SC (129,000 miles) and drove it for 1 week before it stopped accelerating, and died. For the week I drove it ran excellent, smooth & powerfully. So I left it for 4 months and looked to gather as much information on the AOD Transmission, Vaccuum Lines, Fuel System, & Sensors. Plus I looked into common problems associated with the Supercoupes & Recall Parts.
I am guessing the cluches are badly damaged, but if anyone can suggest other possibilities, anything else that could be wrong... I am open to last minute suggestions. I am just about ready to pull the trans and get it diagnosed professionally.
Symptoms-
----------
1. Tendency to stall in Park as soon as it Starts up.
- CPU Chip needed to relearn settings. Forced Idle @ 3000, then 2000, finally held a 1000rpm idle before the CPU took over and held the idle.
2. In ALL gears (1st, 2nd, Drive ODrive, Rev) Idle drops to 500 rpm and usually stalls dead, violently.
3. In neutral, sometimes the Drive Shaft vibrates, or shakes back & forth.
4. Once in drive, Idle drops to 500rpm... step on the gas, but it wont budge nor will the engine Rev Up. In Reverse, idle drops to 500rpm, stalls. Restart it in Neutral, put it back into Reverse and give it gas, lunges Foward Violently, then dead again.
I changed the transmission fluid before 'getting a feel' for the symptoms, changed the filter & gaskets...and the Neutral Start Switch/TR Sensor.
Tranmission Fluid was terribly burnt. Yes it all sound bad. I was Anticipating further problems, even after, solving the startup problem.
Any suggestions?
1-2 Valve? Cluch Plated Welded together? CPU Chip Malfunction? Vaccuum?

Mike 38SC - Read your entire thread on rebuilding the valves on AOD Trans.
Hell of a job explaining that! Hope thats all I need.
