I have an error code P0741 at the 2011 chevrolet captive automatic gearbox the gearbox is 6T45 I changed all parts of mechanics and hydraulics and I see P0741 that says the coil of the coupling converter is blocked or it works incorrectly.
DTC P0741: Torque Converter Clutch (TCC) - Stuck Off
Circuit/System Description
The torque converter clutch (TCC) pressure control (PC) solenoid is part of the control solenoid (w/body and TCM) valve assembly and is not serviced separately. The shift solenoid (SS) 1 supplies transmission fluid to the TCC PC solenoid when commanded OFF. The TCC PC solenoid regulates transmission fluid through the TCC regulator valve in the lower valve body and the TCC control valve in the pump, to the TCC when commanded ON and exhausts fluid when commanded OFF. When the TCC is applied, the engine is coupled directly to the transmission.
Your best bet , take it to a qualified repair shop.

How to prevent the transmission from damage
(The filter usually is screen type and can be cleaned when remove bottom cover. but this is not to be done at regular maintenance inspection.)
- Regularly check your parking space for leaks. Doesn't matter, is it the engine oil leak, power steering fluid or transmission fluid; if you discover any, get it fixed before it caused something serious.
- Once in a while check the transmission fluid level and condition. Not all cars however have the automatic transmission dipstick, in some cars, for example, in late Volkswagen models, the transmission fluid can only be checked by the dealer. Consult with your owner's manual for details. If the transmission fluid level is too low, there is a leak somewhere that needs to be fixed.
- Change the fluid as often as it said in your owner's manual or when it becomes too dark (rather brown than red) or dirty.
Also, keep in mind that an automatic transmission can not be drained completely - there is always some transmission fluid left inside the transmission (the torque converter, in the valve body, etc.) which means you only can change about %60 of the fluid at once. This is one more reason to change it more often.
- Use only the same type of the transmission fluid as specified in the owner's manual or on the dipstick. Some vehicles (e.g Dodge Caravan) are very sensitive to fluid type
- Never shift to the Reverse or Parking until the car comes to a complete stop.
- Never shift from the Parking mode when engine rpm is higher than normal idle.
- Always hold a brakes down when shifting from Parking.
- The automatic transmission can be damaged if towing with the drive wheels on the road. Always use a dolly or place powered wheels on the towing platform (if the vehicle is front wheel drive - tow it from the front leaving rear wheels on the road.

DTC P0446 Evaporative Emission (EVAP) Vent System Performance
The vehicle control module (VCM) monitors the performance of the evaporative
emission (EVAP) system by applying a predetermined level of vacuum to the
EVAP system and monitors the vacuum decay rate. The VCM sets this diagnostic
trouble code (DTC) if the vacuum decay rate is more than a predetermined
value. The VCM monitors the amount of vacuum and the amount of pressure
in the EVAP system by monitoring the fuel tank pressure sensor. For
this DTC, the VCM turns ON both the EVAP purge valve and the EVAP vent
valve when the Conditions for Running the DTC are met. This applies
an engine vacuum to a closed EVAP system. The VCM turns OFF both the
EVAP purge valve and the EVAP vent valve when the system reaches a correct
amount of vacuum. The EVAP system should quickly RELEASE the vacuum
in the EVAP system with the EVAP purge valve OFF and the EVAP vent valve
OFF (open). This test indicates a blocked or restricted EVAP vent path
if the EVAP system fails to release the vacuum quickly enough.

There will be a plug on the bottom of the transmission casing to let the old gearbox oil out.
On an automatic trans the filler is usually on top at the trans dipstick.
On a manuel trans there is a plug about half way up the trans casing.
Drain fully and put in correct type and amount according to your manual. Do not put any old trans fluid in use the type and quantity recommended by the manufacturer!
I find myself just going to a Quick Lube Shop and letting them do it for a few bucks more.. They get it right and it's faster than me doing it myself.
Hope this will FixYa!

if you stay in cold weather, use 5w-30 for engine oil, if warm weather 10w-40 oil THOSE FOR ENGINE..
FOR automatic gearbox use type MERCON V atf or D III

The error that I'm showing for error code P1133 is
P1133 Heated Oxygen Sensor (HO2S) insufficient switching bank 1 sensor 1(Rear Bank). I would suggest having both of your Oxygen Sensors replaced if you haven't already had that done. Hope this helps. Thanks for an honest rating and for using FixYa.
