Just find the transmission pan underneath the vehicle & you'll see a drain plug. You'll need I think a 14mm wrench & a drain pan to catch the fluid & you'll need to get 4L of Dextron III ATF. To refill it look under the hood & you will find another dipstick near the passenger side firewall pull the dipstick out & fill the ATF in there. Make sure to get a funnel & fill it gradually check the dipstick every time you put a litre in to check the fluid it's pretty easy. :thumb3:
