I am wondering what is better to run in my 1992 civic si hatch. I bought some mobil one fully synthetic transmission fluid but haven't put it in yet. Also how often should transmisson fluid be changed? Tell me what you all think, what do you all run how does it treat you? thanks -Allen

 

I run neo trans fluid and I change mine every 20,000 to 25,000. I think recomends every 30,000. I like the NEO fluid I would recommend it

 

i use the mobil 1 syn. tranny fluid...it works fine

 

I use AMSOil synthetic in mine.

Works great so far. Oh and its a synthetic. Expensive ****.

 

The tranny fluid works good.

 

10w30 or Honda MTF. The Mobil Syn. tranny fluid is for automatics.

I know D trannys, do YOU?

 

Another Mr. Bone "TuDe" thrown at us.

 

I guess you have nothing better to do but go around CRYING because you are clueless and have no idea.

Research is key.

 

It says on the the bottle I have here in my hand that it offer maximum protection for manual transmissions where an API GL-5 quality oil is recommended. What is recommended for a d=series tranny? Sounds like its meant for manual and automatic trannys.

you dont buy mobil one transmisson fluid cuz thats for auto. you buy the mobil one gear oil.

 

Although Mobil one gear oil may be acceptable for Honda manual transmissions (because of superior formulation, and the fact that gear oil is close to motor oil), the manual specifies MOTOR OIL. A more appropriate fill would be Mobil-1 10W-30 (as specified in the manual).

mobil 10-30 is good,

don't use redline, not good for honda's.

 

Keep in mind guys that the things that make an oil good for an engine aren't necessarily good qualities for a transmission. In an engine, wear properties, heat resistance and overall friction are important. The tranny is subjected to much less of these stresses. The syncro's in a honda tranny need a certain amount of friction to work properly... meaning that if you use some super-slippery lubricant it might be great for the gears, but would result in torn up synchro's.

There's stories of people running into problems after using various synthetic oils in the transmission. Most of them seem to be heresay though. Personally, while I run Mobil1 in my engine, I choose to stick with Honda MTF for the trannies. Wear is rarely the thing that kills a tranny anyway... it's abuse such as mis-shifts, forcing into gears, etc...

 

Would 100,000 miles of trouble free operation of my 1992 Honda Civic with Mobil-1 motor oil as the transmission fluid sway you at all?

honda does not recommend syn. tranny fluids..30w dino. juice works best

 

yup, yup

 

sounds good to me. I like to here all this info to make a more educated decision. ttt

 

Ummm. Honda doesn't recommend 30W. Its absence from the manuals confirms that, but where does Honda recommend against synthetics?

I just put in BG Synchroshift Synthetic MTF. Works AWESOME....

Also, here is a post I recently made and you can get some more views on it.
