This afternoon while on my commute home from work in horrid Thursday evening LA traffic, all was well until about halfway through my drive. Suddenly I noticed my CEL was on and the info screen said "TRANSMISSION SERVICE REQUIRED." You gotta be kidding me I thought! I immediately checked the codes unsing my ScanGauge II that I always have hooked up while in motion. It was giving a P0740 and P0700. Torque Converter Clutch Circuit Malfunction and Transmission Control System Malfunction were the code definitetions respectively. No bueno! The symptoms it exhibited were the OBDII RPM output was stock at 6000 RPM, though the actual tach was registering correctly. When accelerating from a complete stop, the car would severly bog, like worse than if in W mode. It was as if the car was stuck in 4th gear it seemed like. Once going about 20mph, it seemed to act more normal, though I wasn't noticing the physical feeling of any shifts going on, but the tach was indicating that either it WAS shifting once closer to highway speed, or the torque converter was operating. The 6000 RPM reading was coming from my ScanGauge which is directly coming from the OBDII connector. Speedo was also working normally as was OBDII speed reading. Lastly but maybe most importantly, the gear position screen was just a " - " No letter or number. I was afraid to pull off the road to try shifting around manually as I was on my way to an appointment that traffic was already making me late for. Once I got to where I was going and was going to head home, I first cleared the codes and then started the car. It fired right up and NO CEL or any shifting issues. OBDII RPM reading was normal, and shift position screen was properly displaying the correct gear position and power was restored as normal. Has any one ever experienced this, and should I be worried. I plan to do a flush here finally ASAP with fresh Mobil 3309 fluid and the special "tool" that chefricky kindly loaned me which I need to get back to him. I wish I could get my new DiCE tool connected up, I've been having issues with getting my "new" laptop updated to allow for IE 11 to install, it's corrently on IE 8. Guess I should just lug my PC tower down to the garage in the meantime since that DOES have VIDA installed on it and working.
So any ideas??
