Stand-alone Transmission Cooler Parts List

Simon asked me to outline a parts list for his transmission cooler line installation. Thought it might make a good sticky for everyone but that is not my choice. If everyone thinks it might make a good sticky...let the mods know.

The following list is mostly Earl's fittings and hose with a B&M Supercooler. Prices are from Summit Racing or Jeg's. I personally feel that this is a very good street/strip or bracket car setup. With this setup you can bypass the radiator completely. Leads to better and more consistent transmission fluid and engine coolant temperatures.

Qty: 1 - B & M Supercooler
#70274: $93 (without fan)
-or-
#70298: $190 (with 7" fan)

Qty: 2 - Transmission Fittings
Earl's
#981662ERL: $3 ea.
1/8NPT to -6AN Straight Fitting

Qty: 2 - Cooler Fittings
Earl's
#981668ERL: $5 ea.
1/2NPT to -6AN Straight Fitting

Qty: 1 - Hose
Earl's

Perform-o-flex Braided Hose
Size -6
20 ft. length

Qty: However many you want - Cushioned Line Clamps
Earl's
#171008ERL: $9.50
Package of 5

Here is where you have a choice so I'll list a few hose ends you can choose from. These are the Swivel-Seal design and work well.

Qty: 4 - Hose Ends
Earl's
#800108ERL: $6.25 ea.
-6 hose to -6AN fitting
Straight

#804606ERL: $17 ea.
-6 hose to -6AN fitting
45 degree

#809106ERL: $17 ea.
-6 hose to -6AN fitting
90 degree

This thing is not a necessity but it damn sure makes cutting the hose easier:
Jeg's # 555-80576 Hassle-Free Hose Cutters; $34

To prevent scratching your new fittings:
Jeg's # 555-80548 Vice Jaws; $25

All that is left for you is to mount the cooler and run the hoses where you want. Cooler mounting is something I'd rather not get into due to so many different locations and personal preferences on mounting designs. You can mount the cooler in front of the radiator, up against the radiator, under the radiator, under the fender, behind the front valance, etc, etc, etc. Anywhere you can get a decent airflow will work fine. Some of you will say that twenty feet of hose is too much. I would rather have a few feet of hose left over than come up seven inches too short. I prefer Earl's fittings and hoses due to a) quality; b) price; c) availability/selection.

Ok Simon......start ordering. :bananaman

 

I agree with the 20' of hose... I bought 15 and I dont think I could put my cooler in front of the radiator, only in front...

As for the Earls vs other fittings... I ordered Jegs due to price and I only needed a few, but they seemed like good stuff. But there is a ton of Earls stuff out there and not a whole lot higher. Great list of stuff BTW

 

Use metal lines for as much of the distance as you can. Every professional that I know says to use metal lines for cooler connections. A short piece of medium pressure hose from the lines to the cooler is fine but keep them mostly metal lines.

 

I'm running all mine braided now.. no metal at all... I'll see how it works out.

I've always ran the metal ones before but wanna try this out for routing purposes

 

I keep hearing that you should use metal as far as possible, but both stmanser and myself have had our metal lines hit a pulley and get eaten through. May as well use the more flexible stainless braid and route it in a VERY safe area, and screw it to the frame and fenders, rather than bend it and hope it stays where you want it.

Mine got bumped when I was under there and I didn't know it until I started to see a pretty fast leak. Found out it was bouncing up and just touching the pulley for a second at a time, until it had a nice nick in it that started to leak.

 

Thanks Shadow

 

this part number should be
800106ERL

but other than that, looks great... thanks

i will start ordering the parts real soon

ok.. so i need to order the entire top list, and then decide which 4 fittings to use.. i guess i will need 2-45* and 2-straight fittings.

and then you said do not use the radiator cooler.. i am assuming that the fans setup would be the best..

can you mount that cooler with the fans inside the car? just curious

 

Since I am at work I can't slide under the car and look right now but can you get to the fittings on the transmission pretty easy with it in the car? The reason I ask is I think my AN fitting is leaking a bit on the front hose and need to check it out. I have almost exactly what Shadow listed with the only exception being I used the smaller cooler #70265 in front of the battery tray. No metal and it works and looks great.

 

Ive seen them in a few cars w/ fans on them... like inside the trunk or passenger compartment... Id just run them to the front like they are supposed to be.

The fittings from your transmission to the line... I used a 90 for the back one and a 45 for the front IIRC. I'll check later today. I do know the front was a 45 degree as this way it came out and angled away from the dipstick. Then I used straight fittings to connect from the line to the cooler.

 

yes i did my line with tranny in car it was on lift tight fit but you can get in there

 

You can tie the metal lines down (and should) to keep them from moving too. They just have to be insulated with rubber or plastic to minimize wear. Min are tied at the bellhousing and the front of the pan. That keeps them secure and away from pulleys and if you bump them they stay put. If you want to run them to the frame and follow it up you can do that but I prefer to tuck mine in close to the tranny and engine so there is less chance that something will hit them without me knowing it.

 

Why? You always have these "professionals" that you quote but never any scientific or mechanical reasoning behind their suggestions.

If you really want to get technical about this we can begin by discussing the harmonics that set up in a metal line caused by a running internal combustion engine. These harmonics will cause a vibration throughout the line which will increase as the line nears the point of connection. At this connection there will be a substantial vibration. Hence....a point where, eventually, you will get a leak. Braided hose will not be affected by these harmonics.

Now what?

 

well i can say i agree with SD ..
i have a metal line and a braided hose line on my car.. long story...
the metal line is leaking.. the braided line one isnt

and the stainless hose line is 1/2" thick and wont leak right away if rubbing.. the steel line will get cut through almost immediately.. the reason i initially went with the braided hose, that and it looks nicer

 

Hey, Shadow, thanks for taking the time to research and list the parts. AFter the past few threads regarding AN lessons and transmission "issues" there will be at least 3 or 4 of us in the immediate future that will be using this information to run some tranny lines.

Personally, regardless of what is "recommended", I think braided line is MUCH easier to work with than steel line, looks WAY COOL, and there was something else, but after those two ideas, I really don't need a third

 

Maybe third was just that braided line is more "flexible" (sorry for the pun, had to do it)
