Someone has to be jerking me around somewhere. Since I am getting the clutch replaced shortly I was going to get the fluid changed too. The dealer told me the weight of the fluid is “MTF 75W/85”. The local autoparts places all say that is axel lube, and really heavy for trany fluid. Tried googleing it and I cant find anything. Help, please. Its an '04 Hyundai Tiburon GT, with a 6 speed manual. 60K salvage title. ---

I use redline MTF 75W90 in my MINI cooper so I would guess that the weight for your hyundai is correct. ---

Hyundai Motor Company of North America specifies API GL-4 SAE 75W-90 gear oil for the manual transmission in your vehicle. Tester ---

Some manual transmissions use ATF…Some use 10-40 motor oil…And some, like yours, use gear oil, the same type that’s used in rear differentials. Commonly called “Ninety Weight”… ---

But I sure as heck wouldn’t worry about changing it yet. ---

I don’t know how to pull the transmission without draining or losing gear lube. After 60K, I wouldn’t put dirty gear lube back in. Get API GL-4 gear lube, 75W-90. That is the proper stuff for you. ---

I don’t think you will lose any transmission oil when it is removed from the engine. ---

Just out of curiosity, where did you acquire the vehicle? Recently? ---

If the tranny calls for GL-4 do NOT use GL-5. Some GL-5’s say they are compatible with GL-4…and they are NOT. GL-5 may contain sulfur which may eat away at at Brass gears. Just be sure to use the correct oil. ---

If you insist on changing the tranny fluid, go ahead, but I would not.
