how can i check my transmission fluid on a 2005 bmw 545i with no dipstick
You can't check the transmission fluid level/condition. BMW calls their fluid "lifetime" fluid, I still changed mine at ~70k miles. The rule of thumb is: Once you reach 100k miles, don't bother you will probably do more harm than good by replacing the fluid then.
