Manual Trans Oil Cooler
 

Hey guys
nothing came up on the search, only the stillen auto oil coolers, but i need one for the manual.

anyone running one?

No one is running one that I know of. One guy WAS going to put a temp sensor in and monitor the temps. But he has not posted anything. That's been months now.

There was a gunmetal gen 1 Nismo.....can’t remember if it was a trans or diff cooler....it was a long time ago, when I was a newb here, long before the MA diff cooler came out.

I had his profile page saved in my favorite. But now, somehow the link came back dead. His username was supposed to be “champion” if I am correct. User search came back negative now though. Dang it....

Think it was a diff cooler from GTM that he had a thread on.

That’s probably it. Thx. Back to square one....

ahh, thought about doing that too...whats the difference between the auto and the manual in terms of cooling

The auto already has a pump and lines. All you need is a core and reroute some lines from the cooler in the radiator to the new core.

The manual it splash oiled so you'll need a pump to circulate the fluid along with lines and a core. Depending on were you want to mount it you might need/want a fan like Rusty has on his diff cooler

What makes you think you need a cooler for your MT? I'd get some temperature measurements before going to all the trouble/expense of installing pump, lines, radiator, etc.

If temps are actually higher than what you are comfortable with, changing the trans fluid to a different type, viscosity, etc, may help.

To install a lube cooler for the manual tranny will cost you over $500.00. Need a quality cooler that has to be mounted in the rear. A Tilton continuous duty pump mounted in the rear. Plus your stainless AN-10 hoses and fittings. You have to use a banjo fitting on the bottom of the tranny to pump the fluid out. IF you are lowered. You WILL wipe out that fitting the first time you scrap. You have to drill and tap a hole in the side of the tranny for a temp sensor near the bottom. I've put a lot of thought into this a while back. It's not worth it unless you are pro level racer.

ahhh gotcha, i thought it would work like an oil cooler without the fan....but makes sense now

well the. thing is I ran MT90 and boiled it at the track....I guess some spewed out of the pressure tube and now my car reeks of oil

yeah I guess it's too crazy for the level of tracking im doing...still i dont know how i boiled the mt90 on a freezing day

You might have boiled the diff lube. It's been known to happened. It smells ready bad. It goes out the vent tube and lays in the rear sub-frame.

If it came out of the tranny vent tube. You could see a trail on the tranny. Can you? No one I know has ever boiled lube out of the tranny. If you did. I'm thinking you over filled it.

do I just wait til it goes away? i had just put mt90 and 75w90 thats the reason it could be both, and I dont know which one

I think the trans fluid might have been overfilled but im not sure cause theres no trail on the tranny

I have never boiled gear or engine oil before, never even herd of it. Hydraulic fluid yes, coolant yes.
1. Do you have a PS cooler?
2. Are your fluid levels correct after the boil?
2A. PS
2B. Clutch
2C. Brake

The diff has been known to puke once in a while. It's happened to about 3 people here in the forum.

I guess I will raise my hand. Diff cooler is a must have.

I was going to say the same thing. I am one that lost some diff fluid while driving the dragon. It never happened on the track!

smell is coming from the trans tube, i think it was overfilled. Nonetheless, i think a diff cooler is a good idea

The diff does run hot. If you have the oem vlsd. After it gets hot. The silicone breaks down and the vlsd gives up the ghost.

lol the ghost fart?

Nah....the vlsd no longer works right until it cools back down. If too many hot cycles. It just quits. Mine would work ok for the first 10 minutes or so of a session, then slowly quit working like a vlsd. Toward the end of it's life. It would quit after about 5 minutes and wouldn't come back until the next day. That's when I installed the OS Giken LSD.

yeah, this is my next mod for sure

should i get the 3.9 final gear set too

hey so all fluids are at correct level, also no signs of a spill anywhere (no traces) what is a ps cooler?

ps coooler = power steering cooler.

Tip on the power steering fluid level. If you track. DO NOT fill to the max line. Fill only to the add line. Reason why. When the fluid gets hot. It will expand and over flow the reservoir. Leaving a nice mess to clean up. Z1 makes a power steering cooler.

I have one.

I have Concept Z's PS cooler :tup:

ahh thanks for the info, good to know. Im going over all the fluids on monday, diff 2 quarts and trans 3 right? going to put redline 75w140 in the diff and oem trans fluid back. going to see if the smell goes away

ps cooler worth it?

The ps cooler is worth it IF you track hard.

Haven’t window shop in a while, didn’t know conceptz sells a kit. Good to know :tiphat:

I need a PS cooler but I got find a place to mount it lol. Too much stuff up from, radiator, 72 row oil cooler and FMIC. Go fast race car problems!!! :rofl2:

okay guys, changed the diff fluid and it was boiled. Now my question is, after the first day i noticed the smell, i did another 8 sessions the week after. did i possibly ruin the stock nismo diff using the redline 75w90 and running that mf? just put 140 weight as per specialty z

You didn't ruin it. It already sucked. LOL If it got low enough on oil to get a bearing, you would already know. It would be very noisey and whine like crazy. If you are not experiencing that, you are good to go for now. You need a diff cooler or it will happen again.

haha gotcha, thank you for the heads up and the info. ive been planning on a 1.5 os giken. also been considering a quaife. going to do all bushings/brace/finned cover and cooler at the same time. just need to decide on which diff

Don't forget the Wavetrac. It is a nice diff also. You don't need a finned cover if you do the diff cooler.

haha great another in the mix. ive heard mixed things from e46 guys about the wavetrac.

i looked into changing the gearing but having a 2019 nismo dont I already have the 3.9?

LMAO, that is a problem, listening to Bimmer Boys! I ran a Wavetrac with know issues and good results.
