hi i hope this doesnt get deleted but i searched and couldnt really find my answer, i have a integra but i search here and check out things for my cousins 91 240. im asking does the tranny take regular motor oil like 10w30 or gear oil 75w90, or both? because lately the gears have been slipping if you press on the gas it revs up to like 4k then catches

 

sounds more like a clutch issue maybe?

FYI the transmission is designed to use 2.5 liters of GL-4 gear oil (manual tranny) or 8.3 liters of ATF (auto tranny)

 

ok so i put 2.5liters of gl-4 gear oil in the tranny? it doesnt have differential since it doesnt have lsd right?

 

Diff is located at the rear of the car, seperate from the tranny bro - this is RWD.

you put 2.5L of GL-4 if the tranny has been drained. If it hasn't, you might want to replace the old oil anyways to see if it cures the problem. There's a drain plug at the bottom of the tranny and a fill plug on the left side of the tranny. Remove both and drain away. If you don't want to drop the tranny to refill it, you can pour gear oil through the hole where the shifter is inserted into (remove shifter, pour oil).

If you can't measure out exactly 2.5L, keep the fill plug (left side of tranny) off while filling the tranny with oil. When the oil barely starts dripping out of the fill hole, you're good to go.

 

i know its RWD, i have FWD im just not mechanically inclinded with rwd yet, i work on the integra and the 240 but thanks, also i had the same problem with my integra, it was slipping madly and when i changed my tranny fluid i can chirp and all that and no grinding

 

Please clarify, does the car have an automatic or a manual.

A slipping manual transmission is a small problem compared to a slipping automatic transmission.

 

its manual of course

 

i cant find GL-4 fluid anywhere and i even called nissan and they said put gl-5 in it? im very confused now. why not to use gl-5? where do you guys find gl-4 fluid in southern cali? i checked all the stores like pep boys kragen and autozone.

 

I pulled the GL-4 rating from the FSM. Try Redline MT-90, perfect for KA transmissions, about $9 a quart.

Besiees, GL-5 has crap in it that can kill the gears and synchros.
