Yes, now I am looking like some kind of a flak-e kind-a- guy.
As I was reading all I could see on your site "replies to your members". I found an answer to one persons issue on same vehicle I have. In turn your people answered his concerns with the trouble code sheet.
Reason I am looking like a Richard, is that my trouble code is not on your list.
worst part is I was not high, drinking or anything. And now what? A certified mechanical great guy with GM's beginning attempting various computers an no support.
this has been the best ride I have owned yet. I have had a boat load of them my first ever computer ride and I would rather have my old carburetor units with 12 1/2 to 1 compression, with big valves an a 501 Crower Monarch cam. This confused computer stuff is not looking to special to me. Especially when I can visually see fine an I am an American that has logic and I get a code 83?

This appears to be a transmission code, I found a code 83 for a TCC solenoid circuit fault. Have a look into this first. It can fail in the open or closed position.

Faulty Transmission Torque Converter Clutch Solenoid: Symptoms
Failed in the Closed Position.

With respect to drivability and performance, a malfunctioning torque converter clutch solenoid (one that fails in the closed position) may not be noticeable. However, if you pay close attention to your gas mileage, you will see an increase in fuel consumption because the engine and transmission are not locking up at highway speeds because the faulty solenoid. Thus, you have slipping, which causes the engine to work harder. The harder the engine works the more fuel it consumes. Slipping also generates heat. Any time a transmission overheats, some internal damage occurs.

Faulty Transmission Torque Converter Clutch Solenoid:
Symptoms - Failed in the Open Position.

The symptoms are different a torque converter clutch solenoid that fails in the open position. The symptoms of a torque converter clutch solenoid that fails while in the open position are quite different from a solenoid that fails in the closed position, as described above. When the solenoid is open, the engine is locked to the transmission so there is no transmission slip. With the transmission unable to slip, the engine will stall when the vehicle comes to a stop.

This type of solenoid failure will set a Diagnostic Trouble Code causing the Check Engine Light to illuminate. The same Diagnostic Trouble Codes listed above apply.
