Codes are back after driving about 30 miles on freeway however no limp mode yet car drives okay.

Code:
P0740 - Power train Torque Converter Clutch Circuit
P0700 - Powertrain Transmission Control System (MIL Request)
Torque converter clutch circuit is some electric thing right what exactly is it?

Another thing in D mode when i press gas fast nothing happens for 1-2 seconds then it shoots, slowly accelerating is okay. i When i use auto stick car responds instantly to gas pedal.

The torque converter clutch is basically the lock-up mechanism to lock the torque converter so that engine rpm is directly transmitted to the transmission. This is supposed to take place at speed of about 35 mph and above. It has a friction disc that locks up by means of the clutch solenoid controlled by the transmission computer. It's possible that the black crud you reported seeing in your filter is from the clutch disc. If that's the case, you may need to replace the clutch, and/or the torque converter, which is a big job involving removal of the transmission.

It is probably getting close to the time to have a heart-to-heart talk with a professional transmission specialist to discuss your options here. The major cost of a transmission job is the skilled labor involved in pulling the transmission out. It's tricky and potentially dangerous and involves special tools and lifting equipment. Then you need to decide whether you want to have the transmission rebuilt or replace it with a used one. It would make no economic sense to put a brand new one in a car that old. You will have to decide whether even the cost of a used transmission is justified versus walking away from this car and looking for another.

Car drives perfect plus i never changed solenoid block yet. To me torque converter clutch is useless, will try to solve it but worst case will install wire mod to disable TCC permanently .
