I need my transmission and differential fluids changed... Anyone know what viscosity (or whatever) of fluids they take... I'd like to run REDLINE fluids in it!!!

I've visited http://www.myoilshop.com and they don't seem to have what my manual calls for

In my S2000 manual it calls for "MTF" transmission fluid, but Redline doesn't have MTF!!!

Also in my manual the differential fluid calls for SAE 90 hypoid gear oil, but I can't find that in Redline either!!!

WHAT are all of ya'll running in your tranny and diff?????????????? gimme some ideas of other things I could do!!!

<U>THANX ALOT</U>

p.s. my car is boosted and I do also do some occasional racing, if that makes a difference!!!

 

MTF is short for manual transmission/transaxle fluid(atf for slushbox)

most common and most proven formula for s2k

tranny: GM syncromesh Friction modified.

sold in all gm dealer, it might be harder to get since most place do not stock those, custom order you need to buy at least a case(six pack).

i got mine from a pontiac dealer after i went to a chevy dealer and they don't stock tho', they can check the part for you in their network so do that over the phone and save some times.

they runs about 12 dollar per bottle, you'll need two.

better shifting feel vs. oem mtf, well worth the money.

LE607 or Mobile 1 75/90 seems to be the most popular choice, i personally runs m1 juice in my. They sold that in most common auto place unlike Le607, a bottle of those is more than enough.

go search up in s2ki, they have a very completed review and why most guy perfer those product over redline's stuff

 

Honda tranny fluid for me with Le607 in differential.

 

^^ Same here. ricks2k.com for LE607.

 

I just bought a qt of LE from Ricks2k. Ships from NY fwiw.

 

So LE607 and GM syncromesh are the favorites then? I took my car to the Honda dealer and they said it was not necessary to change them during the first tuneup at 15000.

Problem is I drive the car kinda hard, plan to track it. I also am not always paying attention and dont always push the clutch ALL the way in and get a grind. I would like some added protection.

For the tranny it has gotten a little notchier over time from me doing that. Hey its my daily.

For the differential well I hear a noise from there when I first accelerate with the front wheels turned from a dead stop. It may be the shocks or car frame making the noise from the torque (not trying to make it sound like a v8) or maybe the diff but I do hear something from underneath and rear.

LE607 and Royal Purple are basically the same stuff, different slightly in color. I swear by this stuff.

15k is a good interval for transmission and differential fluid change if you track or drive your car hard. I was changing my oil every 2 weeks (track weekends) and tranny/diff fluid every other month before I started DD-ing the car.

Notchy = change fluid.

Diff noise = But it's an 06!!! How many miles? Lowered? Describe noise.

 

I recently changed my tranny fluid with Royal Purple 10-30, also my rear diff with RP 75-90 rear diff fluid, and as always the engine with 10-30 as well. Got it dyno'd and gained 8 whp. Go with ROYAL PURPLE.

 

Thanks.

I think its just the normal sound a differential makes. Its like one time creak sound. I can only duplicate it if I have the front wheels turned hard to one side from a dead stop and release the clutch and give a little gas to move forward. I think its always been there though.

well...i would suggest Honda MTF for the trans. They have a new formula. It's pretty kick ***. I changed my trans fluid and it seriously feels like a new trans. it's really nice.

I just used some generic 80w-90 fluid for the diff...you could go synthetic if you want, i guess.

I track my car too. A lot.

I would also suggest...pushing in the clutch all the way when you shift. There's no fluid that will give you infinite grind capability. You're eventually going to break something and be sorry that you did. I think it's easier (and cheaper) to be careful rather than replace a trans.

I'm not by any means saying dont drive the car hard...that's what it's there for. I wouldnt mind replacing parts because i drove the car hard and it wore out from track use or something...but i'd feel like a jerk replacing parts that i had abused ...especially if i could just have very well not abused them. I.E. not pushing in the clutch all the way....

 

i work at honda and i beat the hell out of my ap1,(honda mannual trans fluid,and 80/90w honda hypoid gear oil) the best way to go. the only other option that would really make any improvement would be motul oils hard to find motul je import carries all their stuff

honda makes diff fluid? The dealers around here just outsource 80w-90 from like carquest or napa or wherever....

that hypoid stuff says its gear oil but approved for the Goldwing, ATV and other motorcycles. No S.

"hypoid" is a type of gear. "hypoid gear lube" is a type of gear lube. It's not a brand. it's kind of like saying "motor oil".
Hypoid gear lube is kind of stringy. it has a lot of surface tension...it holds together so it will not get sheared apart and it will actually lubricate a hypoid type gear. regular oils will not work in a hypoid gear environment due to the shape and resulting friction type of the gear.

That's one requirement.

Then you need it to be SAE 90 or close. 80W-90 will do.

Honda does not make a SAE 80W-90 or 90 gear oil. So....if you're using the stuff for gold wings or VTM fluid...youre using the wrong stuff. It may be hypoid lube, but it's not the correct weight.

Honda dealers around here outsource to automotive suppliers for hypoid gear oil.

It also has to be GL-5 or GL-6. Which most modern hypoid lubes are.

So 3 requirements have to be met:

HYPOID TYPE GEAR LUBE
80W-90
GL5 or GL6.

If you're buying from honda, you're either getting ripped off on the markup..or you're buying VTM fluid and it's the wrong stuff.

i embarass ricers like i pound nerds.

 

He's technically an e-racer/bench racer, so what do you do with those?

doesnt that fall under "nerd"? I can look it up in my operations manual...

 

Does anyone ever add limited-slip additive to the diff lube or is that only necessary for clutch-type LSDs?

it's only for clutch type. It makes the fluid less smooth and more abrasive so that the clutches will hook up better. I figure it would probably F up a torsen diff

Correcto!
