Condition: Some customers may comment on the SES light being illuminated and a chuggle or surge being felt when driving at higher speeds.
Technicians may observe on the Tech 2 , an excessive torque converter clutch (TCC) slip speed and DTC P0741 set as Current or in History.
Cause
This condition may be caused by seal damage that allows the TCC apply fluid to leak into the channel plate, causing excessive TCC slippage under certain operating conditions, eventually resulting in a total loss of TCC apply fluid pressure.
The TCC may have partial apply fluid pressure or no apply fluid pressure. If excessive slip speed is noted on the Tech 2 and the condition/cause cannot be corrected by using the DTC P0741 diagnostic information, then worn seals from slippage of the drive sprocket bearing inner race on the drive sprocket are indicated

When I took the code off yesterday nite it hasn't came back I checked my oil and it was low reads at the cold mark of stick while car was hot and idling so can that be the problem that the oil fluid is low? How can I check it precisely?

The stick say to check it while idled do I? Also the stick say cold with like little ingraving and above it hot with Ingraving so if its hot already I put oil with car off and check oil with car off or on? If I check it cold should it mark between the cold Ingraving?

It has to be Hot and while engine is idling then you check the level if needed at a little at a time till its on full mark-

So It should read in the middle of the hot ingravings right? Y does the dip stick have cold and hot on it?

Its due to heat expansion of the fluid
