Do not use the old gasket, you will see the bottom part dump with transmission fluid after few hundred miles and you will always check the transmission fluid level every few days.
I just replaced a filter and gasket (115,000 miles). With the front of the car raised up. First, put a jack support between the transmission and engine on the metal bracket holding the exhaust. Then, remove the cross member (4 bolts). Then, the transmission support (2 bolts, 4 small nuts of the transmission rubber mount, and 2 big nuts). The big bolts and nuts, if you can remove easily, great. If not, I have to use the 24 inch breaker bar wrench to remove it.
If you bought the aftermarket filter, it is probably made of plastic. The original is metal (expensive). Also, repair manual says 6 quarts of fluid, I only put almost 3 quarts. So, just to make sure. Start with almost 3 quarts. Start engine, with the brakes and hand brake applied, shift the shift lever on all gears back and fort for few times. Then, put in park with engine running at idle. Check fluid level, should be on the bottom 20 degrees line when the engine is cold and upper top line when the engine is in normal hot temperature. Then work your fluid from here if it needs more. Do not overfill. The top line in the dipstick is the maximum when hot.
By the way, check your transmission rubber mounts. Most probably cracked or broken rubber.
