Allison trans cooler line fittings

[madmatt]

has anyone found a fitting that will screw into place of the factory trans cooler line fittings? theyre a m22X1.75 which other then the factory fittings,,, i'm finding nothing on. Running a new cooler setup and all i lack to fire the new engine and trans in some fittings.
BUT if no one can help with that anyone have some old leaking trans cooler lines laying around they'd donate? I'll pay the ride and just need the ends plus about 6" of the hard line that comes out of the trans.
Thanks,
Matt

Wha...
there are upgraded transcooler lines you can buy, alligator performance sells them in 1/2"id and 5/8" id, i have a set of the 5/8" and they trhredded right into place on the stock cooler and the ppe cooler?

 

[madmatt]

mmm i'm running 5/8 TOC to -12 fittings. fabbing up a whole different setup. had some m22x1.5 to -12 adaptors but no go. i'm bypassing the factory cooling circuit in the radiator and running just a big remote mount with a fan on it.

Hmmm, well if the threads are different than stock idk where you could go, maybe summit or jegs?

Good luck, sounds like it'll be sweet when its done!

 

[madmatt]

Joe at PPE has something different threaded into his,, waiting for word back as to what he did or where he got them

03+ should be -10 o-ring seal. My radiator fittings are nothing more than a -10 male o-ring to -10 flare. I believe it is a 7/8X16 thread. I'm not aware of any metric sized cooler fittings.

i'm talking about the fittings in the trans

going from this cooler to the trans,,

Thought the 03+ all used the same fitting in the radiator, trans, and cooler? I know my 01 is a -8, but I don't have an 03+ to check in front of me.

hmm maybe the idiot at the parker store sent me down the wrong path then,,,,,, i've been chasing a ****ing m22 x 1.75 fitting for over a week,,, i'll run to town and see what i can't come up with tomorrw then thanks.

I would ditch the hose clamps on your cooler.

X2. Go have some made.

 

[madmatt]

why? how much pressure do they see? We spoke about how much the cooler sees once before and seemed to be within reason of what a barbed fitting and a clamp could hold. not arguing but could i have maybe misunderstood what pressure the cooler sees?

 

[Mike L.]

The cooler pressure can spike to 200 psi running stock mainline pressure ( 232 psi ). It can get a lot worse running higher mainline like a .130 shim ( 255 psi ). And even worse running my pressure regulator spring which is adjustable from 290 psi- 350 psi. Clamps are scary. Be carefull.

My clamps held just fine matt:thumb:

 

[madmatt]

i use .140 shims,,, hmmmm looks like i'll get some made up. I understood wrong. It was my understanding the cooler saw only a portion of line pressure. oh well glad ya corrected my thinking. :thumb:

 

[madmatt]

ya know i was thinking we had clamps on yours ryan. was starting to think i had lost my mind lol

 

[Hot COCOAL]

I have the two fittings with the purple clips that screwed into the mike l/ppe cooler, i took them out cuz i got the upgraded cooler line and those screwed right into the cooler. I'll take a pic and post it if you want to see them, if you want them after that i will send them to you

 

[madmatt]

I've got some here right now that work. Heck if I wasn't chasing the wrong size I'd had this running last week

What cooler are you going to run? I've been fighting high tranny temps all year on the racetruck, nothing but problems running two classes. Even just running one class after 2 runs it's already at 210. Going with a fresh new tranny next season and want to keep temps under 200. BD's cooler looks pretty good, what's everybody here running? I really want to ditch the stock heat exchanger but by the sounds of everybody i'd be better off leaving that in the circuit.
