I have a slow leak on my transmission. I need to fill the transmission with more fluid before it causes damage. I was told GL-4 is good, but i want to make sure.

thanks

if it's a t-5 the douche that told you gl-4/5 is wrong!!!! it uses atf/ dextron III/mercon

OnyxCobra

yup definitely Mercon ATF for the T5.

My tranny is filled with what looks and smells like gear oil...guess I'll be draining that sucker and refilling it with the correct fluid.

i just fill mine with cheap *** atf.it leaks out pretty quick and i dont feel like taking the tranny out to fix it.

Even though ATF is the correct fluid. Your leak will probably get worse with the swap.

Fix the leak.

you're absolutely right Jfsram. Last night i just figured out my leak was coming from my drivers side valve cover and the oil ran underneath the trans because of the forward motion while driving. The leak was happening near the clutch and it just came to me yesterday that the clutch does not have oil. But thanks for the info. At least I have the information for when I want to change my trans oil.

trans fluid is red and oil blackish...that should of been easy to figure out

if your trans came out of an older car it does take gear oil
