2011-2013 Kia Optima Manual Transmission Fluid Service Gear Oil Change 

BIG TIP: I only used 3 quarts, please refer to the owners manual as to how much you should put into the vehicle. I sold this vehicle awhile back so I am unsure of the specification.
• Once you have the proper amount in, check your fluid on a level surface!
REMOVE FILL PLUG FIRST It let’s fluid drain out better.
• Any questions please leave below!
