A guy whose opinion i respect and trust told me he has been using Mobil 1 Synthetic 10w-30 in honda trannys for as long as he can remember, it works great and hes never had any problems. since im finishing up my swap right now i was wondering if this was an ok idea to try out? anyone else ever try this?

 

i use reg. 10w 30
dont use gear oil.

 

i wasnt going to use gear oil. anyone else?

 

i use Mobile 1 10w-30 in my z6 tranny nothing is wrong with it sometimes i just change it often now and then just to keep my tranny and a good condition.

 

I use 10-30 in my track car since day one, no problems whatsoever.

 

its ok,I use castrol 10w-30 gtx synthetic with no problems in 50,000k

 

In older hondas (like pre-94) honda hadn't invented MTF yet, so they suggested running motor oil in it. I use GM Syncromesh Friction Modified and its the smoothest shifts ever. Even with a SS installed.

Only downside, the ish is like $15/qt

 

sweet. Thanks for the replies guys. I appreciate it.

 

i ran 10-w-30 for a year and last week i switched to gm syncromesh friction modified..oh boy what a difference...i would suggest to just use the syncromesh

 

I only use Genuine Honda MTF. It's formulated for the Tranny... motor oil will cause premature wear.

 

deffently use honda MTF or some other MTF i did use motor oil in my old tranny felt like **** new tranny, with MTf ***** like BUTTA

 

Do not use regular motor oil!!!! Use Honda MTF your syncros will thank you. If you have a Honda LSD and use regular motor oil it will ruin the LSD. In closing only use Honda MTF or you may ruin your tranny. I havent personaly used the GM syncromesh but I have heard that it works just as well.

Honda did when it shipped out its DA and DBs. Sure there are better transmission fluids out there, but if it was such a problem, don't you think honda WOULDN'T have done it?

 

where do u get this GM Syncromesh from?

 

I only use Genuine Honda MTF

 

i'm gonna change my tranny fluid today, but i just wanted to know is the fill plug any different (or in a different location) from the the usdm d series trannys? does the fill plug use the 3/8 in drive from a socket, or is it something else? this is on a jdm s1 cable tranny by the way

 

Genuine Honda MTF or Redline MTL/MT-90.

 

GM Synchromesh MTF here.

 

on my 92 civic, filling plug was 17mm. What you're talking about is drain plug. If you're looking at the drain plug dead straight, fill plug is to the left and up about 4".

As far as using motor oil....
I replaced my axles yesterday, and I filled it with 10W30. The repair manual says to use 10W30, so that's what I used. It worked well for 220,000km so it should work fine now.

But you notice how often these trannies grind? Honda MTF would be the minimum fluid I would run. If you read the factory manual, it says 10w30 can be used, but only as a temporary solution. Honda recommends the Honda MTF. I used it with no problems. The GM synchoshift works well too, that is what I am running right now. You can usually get it at any GM dealership.

My local dealership will get a visit from me this week. Thanks a lot.

 

yeah you can find gm synchromesh at any gm dealer

 

Is the GM Synchromesh a GL-4 or GL-5 based lubricant? Everything that I've read states that GL-5 lubricants are bad for the synchros in a honda tranny.
