Found 2 Litres of this stuff floatin about and she's due a change, will this be ok???
(DC2 Type R - 2000 model - 87,000 miles)
Thanks in advance people, Lee.

 

I wouldn't advise it...The synthetic would be to slick and Honda recommends their Manual Transmission fluid and only to use 10w30 or 10w40 motor oil as a temporary replacement, seeing that is doesnt have the proper addititves, and continued use can cause stiffer shifting

 

x2
L.S.D.'s gotta have the right additives.

Ignore the above statement, but stay with OEM Honda fluid.

 

im throwing gm syncromesh friction modified out there
But yeah way too heavy weight for your tranny

no it doesn't...it's not a clutch pack LSD.

75W-90 gear oil would be roughly equivalent to a 10W-40 engine oil
80W-90 gear oil would be roughly equivalent to a 20W-40 engine oil
80W gear oil would be roughly equivalent to a straight 20 engine oil

Honda recently went with a weight that's similar to 5W30 but their previous blend was more like 10W30. Some people see the 75W90 and immediately think it's like molasses or something.

To the OP: Unless you are unable to get Honda MTF for whatever strange reason, or you are running a specific type of clutch pack LSD - stick with what others have said.... Honda MTF.

FWIW, I use a 50/50 mix of GM sync and the old Honda MTF because I have a couple of boxes of it laying around.... works good

 

good info i didnt know it was ok to mix fluids

OEM fluid does have the right additives built in. Red Line for example doesn't. You'll get YOWWWLLLLLLL every time you back out of parking spot. I put the OEM MTF back in.

I don't know which redline fluid you were using, but it must have been the MT90 which is not recommended.

The MTL is what I used before with a clutch pack and it worked beautifully. The yowl you speak of is likely not related to the LSD as it is a mechanical unit.

This 70W80 GL-4 Gear Oil (SAE 5W30/10W30 engine oil viscosity) is designed for use in manual transmissions and transaxles. Provides excellent protection of gears and synchronizers and its balanced slipperiness provides a perfect coefficient of friction, allowing easier shifting. Popular in many BMW transmissions and in most Honda and Acura transaxle applications.</TD></TR></TABLE>



But with that said, it will still vary from user to user which is why others will swear by syncromesh over OEM or Redline etc.

Well the MTL was what I did try. Redline recomends "Limited-slip transaxles may require the 75W90 Gear Oil to
prevent limited-slip chatter." But after telling th' import shop 3 times that ITRs had LSDs, they put MTL in. ACURA put the OEM fluid back in and told me what I related above and noise was gone. Most Honda and Acura trans. don't have LSDs.

Be careful with gear oil. A lot of them are not compatible with the brass parts used in our trans'.

I did recomend the OEM MTF.

 

Honda is up to MTF3 now here in Japan. I think the Honda/Acura dealers there finally started carrying the MTF2 (true tranny fluid). The original Honda MTF was essentially just a 5 or 10W30 motor oil. I haven't seen first hand as I haven't been in the US for many, many years but apparently most dealers just filled the tranny cases with straight motor oil there.

The helical slip doesn't need any special fluids, hence the reason why that import shop used the MTL and not the 75-90 fluid. The LSD's that Redline are referring to are clutch pack types, very different from a helical unit.

I didn't mean to direct it at you. General fyi.

 

Yah, yah, no prob. This subject has lots of ins n' outs. To add, my experiance above was right after break in and a baseline dyno. I was trying to reuce friction in trans and pick up a free horse or two but had the problems with the LSD and MTL so it didn't work out for me.

 

There is only one simple answer, Honda's MTF.Cheap enough to change frequently. No need for discussion.

 

i wonder how our local mtf compares to the mtf3?

I know preferences vary from user to user, but I switched from the MTL to MT90 years ago and will never go back.

The MTL is way too light, and resulted in notchy shifting, among other issues. Plus an overall feel that the gears were not lubricated enough, especially when hot. The MT90 quickly rectified those problems.

Both my mechanic and I (he runs a race spec CRX in the Canada GT Touring Championship class) switched to the MT90 and have been singing its praises ever since. This is on both a street/circuit ITR and a track only professional race car ... both with the same tranny, except he uses carbon synchros.

I have tried both the MTL and MT90 on a used ITR tranny and a freshly rebuilt one, and the MT90 outperformed the MTL in every aspect. I will never use the MTL again. Too light, too slick.

Both my Mechanic and I have been using the MT90 for a few years now, and both transmissions are in fantastic shape and run beautifully. Longevity is not an issue with the MT90 whatsoever. Both of our transmissions have been dismantled and inspected this summer, and all gears, bearings, and LSD unit are in top shape.

Once again though, personal preference.

 

&lt;---- Amsoil user here... Alrready has syncromesh in it.

I know Walker users it too...

?... I thought gear oil was for differentials and stuff, isn't it bad for your tranny. I'm pretty sure it'll do some damage

 

It would work, but I wouldn't put it in my tranny, I'd rather use honda atf or mtf
