Unbolt the transmission pan. The pan should have a drain plug which can be removed with a 3/8 drive ratchet. Then allow ample time for the fluid to drain into your pan careful not to spill a single drop because you want to add the same amount of new fluid back into the transmission via the dipstick. Locate the shift solenoid on the transmisson valve body. Then remove the enire wiring and solenoid. If you are planning on replacing the whole thing because of check engine light code 0773 then READ THIS CAREFULY. The torque converter may be the actual issue. Have you shift solenoid tested. But first check the wiring to see if its frayed. Also it could just be dirty. If you replace the solenoid keep in mind it is expensive and you will be paying for a $200 part plus the price of tranny fluid, gasket and sealer. Just make sure the shift solenoid will fix your problem. Good luck
