You site is usless and a waist of time
Undo the drain bolt on the bottom of the gear box, but undo the filler first so it flows easier. 24mm bolt i think.....
The manual transmission in a 2003 Hyundai Tiburon requires 2.3 quarts of gear oil.
API-GL-5 or SAE 75W/85W gear oil. 1986-89 is 2.2 quarts, while 1990-1994 takes 1.9 quarts
Unfortunatelly NO!
Overdrive is like 5th gear for cruising in most automatic transmissions, the common place for the on and off button is on the gear selector.
Any brand 90 wt. oil will do fine.
when facing the gear , you will see on the cyl head a big arrow , on the right hand side , it looks like a moulding bit , , but look hard and you will see it ,
time to get new trannie
Engine RPM increases but not the speedometer.Difficulty engaging 1st gear at a stop. Clutch grabs to low or to high.
I would change it. A lot of people neglect on changing gear oil. Most manufacturers recommend changing it, mileage varies, check your owners manual.
remove the side plug and fill til it runs out the same hole, get a pump from auto zone, couple bucks.
Hyundai have added a trick to starting the engine - you need to have the clutch pedal in regardless of whether or not the car is in gear. Unless the clutch is in, the engine won't fire.
