well its my first oil change on a eagle talon after 4 years, now i drained the transmission and put 4 more liters of oil in the engine. I did this sunday and drove the car untill today, needless to say the transmission doesnt want to change gears properly, i drove on the highway in second gear at like 100kmh. NEED URGENT ADVICE, the car is outside at my workplace, i bought 4 liters of transmission fluid, i have the tools necesary to work, i just dont know how to fill the tranny.

Thank you,
Andrei
