2011 Ford escape

Inside the transmission, it will require the removal of the trans pan. You would be better off getting a repair manual, it will give you needed torque specs. You'll also want a torque wrench. Applying uneven torque to a pan bolt can distort the gasket and create a leak. You'll be working underneath the car, so a floor jack and jack stands are also needed, or a lift. Personally, I'd leave this to a shop. Let them flush and refill tranny as well as test/clean all solenoids, and replace the ones that need replacing.
