Listen up - anyone converting a Auto to Manual may want to do this. I made these for all three of my conversions, so I am running the trans cooler as the first engine oil cooler...ala R1. My engine oil temperatures are waaaay cool.

Like I said earlier, there is no known aftermarket fitting to use in the stock trans cooler to adapt to engine oil hose NOR -10an fittings. No problem, make your own.

Process is rather simple....clean up the stock trans cooler fittings, drill out the two barbs, buy two engine oil female fittings and weld the female fittings to the trans fitting threads. WWaaallaaa !!! you are in business.

I made these for a Forum member, so ask him to make you some.

Looks good Tom. I'll take a set if you decide to make more.

 

Geez who could that be for! Fittings look awsome

 

haha.

I suppose there are a lot of us doing the swap right now huh Tom? I think I've figured out my own way to route and connect hoses to the oil cooler. I hope zip ties will hold.

I'll be sure to look for a set if my way doesn't work out. I just pulled out the auto tranny tonight. Its been fun, but its been a pain so far by myself.

 

Do you have a picture of the unmodified fittings both stock and the engine oil female fittings? I have an auto trans cooler I want to convert to a 2nd oil cooler but havent done so because of the fittings. Where did you get your fittings from?

 

Before....

 

Islanders_rx7 is the one doing the current conversion. So for fittings/hoses that you need and what he did to prepare his tranny cooler for oil, just contact him.


Also don't forget the oil temperature gauge

WHAT ABOUT THE OIL thermostat

 

Got an oil temp gauge up and running already Just need to add this tranny cooler to the passenger side to hold me off until I can get a nice oil cooler setup.

Thanks for the pictures. I'll PM Islanders_rx7 for more info


If I'm not mistaken, the stock drivers side oil cooler already has a thermostat in it to regulate the temps unlike aftermarket oil coolers that need an external thermostat.

 

You got it Wan, no problem with the oil bypass.

Any hydraulic shop should have the fittings, I beleive they are 18mm orb to 5/8 37* JIC ( 10 AN )
Should cost about $3 each.

 

Bullshit! Go to ANY shop and buy one - show us.

Here is some more pics

 

And More

 

I've yet to start the engine up to leak check it. I added oil and its not leaking static. Once I get my other parts in later this week I'll be able to crank her up.

 

Good job on that Joe, looks good.

Oh by the way the cooler on post 13 is before I sent it out for cleaning.

 

Here is a pic of the oil cooler line for reference.

 

Soooo - how much to make a set of the converted fittings? How much if I supply the 4 fittings necessary (2 trans cooler and 2 oil cooler fittings)?

I am assuming that you are tig welding them?

PM Me

 

What size thread is the male side that goes into the cooler itself?

 

I dont have an xtra auto trans cooler fitting to check. I dont want to to remove the fitting itself anymore. Refer to this thread https://www.rx7club.com/showthread.p...ghlight=cooler

 

http://www.greenlinehose.com/_pdf/pu...8/Adapters.pdf pg. 96 Ive got 2 of them on my car, off the shelf cant remember the price but $3 per would be the right ballpark. I believe its these that i used to to on my stock oil cooler when i kept it and added an aftermarket 2nd cooler.

 

I'd just opened that link and they do not sell these fittings! These fittings were modified to accept the stock OEM oil cooler lines and go on a auto trany cooler. Look at the pics above!

 

mis read things somewhat... Those custom fittings are definatly custom.
in anycase there are metric to JIC adaptors if anyone wants to go that route. Its what I did.

 

^^^ Sooo where?
