Brandon.........your 5-speed uses automatic transmission fluid. DO NOT USE GEAR OIL. I would recommend you use any synthetic automatic transmission fluid. I use Royal Purple Sychromax synthetic manual transmission fluid.
You add or change the fluid like this. On the driver side of the transmission there are two plugs. One labeled FILL (the upper one) and one labeled DRAIN (the lower one). If you want to change the fluid, remove the bottom plug first then loosen the top one and remove slowly. When the top plug is removed the fluid comes out real fast. So be ready to catch fluid. To fill the transmission put the DRAIN plug back in. It will take between 3-4 quarts of transmission fluid to refill it. I use one of those hand pumps that screws right on top of a quart bottle to fill the transmission. Fill the transmission with fluid until fluid just starts to run out of the FILL hole. Reinstall the FILL plug and you are done.
Hope this helps!
