Overheat on audi s4...install a new thermostat and new radiator no heat air blow inside

i try bleeding but this car have 3 radiator plus the radiator inside the car for heat the air and i dont see any good yet, i take a small pipe attached to the reservoir tank but no luck yet......and i have another issue....i need to find the way to put transmision oil and i have no idea were is the plug to filled.....i go to the dealer and they want to charge $150 only to do that....plus each quart is $22 and i need like 7 or 8 quart according to the dealer.
and they tell me that the dealer use a special computer to fill the trasmision because the fluid need to be heat 80 degrees if not the transmision can be damage...i dont know if this true or they only want the money....i guest if the car is cool the fluid is cool too....so i dont see any diferent to fill the transmision not heating the fluid.....any comment about this can be helpful.....thanks guys! i try bleeding but this car have 3 radiator plus the radiator inside the car for heat the air and i dont see any good yet, i take a small pipe attached to the reservoir tank but no luck yet......and i have another issue....i need to find the way to put transmision oil and i have no idea were is the plug to filled.....i go to the dealer and they want to charge $150 only to do that....plus each quart is $22 and i need like 7 or 8 quart according to the dealer. and they tell me that the dealer use a special computer to fill the trasmision because the fluid need to be heat 80 degrees if not the transmision can be damage...i dont know if this true or they only want the money....i guest if the car is cool the fluid is cool too....so i dont see any diferent to fill the transmision not heating the fluid.....any comment about this can be helpful.....thanks guys!
