Re: Barbed fittings for transmission cooler lines?

Update time, got my fittings and some hose barbs, I'll update with pics when they go in over the next couple of days. Here are part numbers and prices of what I picked up.

These prices are all quantities of two:
9919DFH -6 10 14mm adapter $17.18
3-906-V90 -6 viton o-rings $2.00
709167 90 degree -6 to 3/8ths hose barb $33.98

Total out the door with tax was $58.34 not too bad. The hose barbs also include the covers for the ends of the hose if you are running stainless steel braided hose, which I am not.. but its nice to see them included. Pics coming soon!

Re: Barbed fittings for transmission cooler lines?

Ok, just got done putting the fittings on


The fittings (with part numbers :smile


These are the old lines.... a pain in the butt to replace if you happen to puncture a line or pinch one off. even worse if one gets yanked and breaks the plastic retainer, you would be completely stranded.


as you can see this one was pulled far to the side, i gave it a little tug and the plastic piece snapped and it dumped fluid everywhere. Glad I decided to replace them.


Out with the old...




and in with the new.

Re: Barbed fittings for transmission cooler lines?

Just clarifying, with the 90 fittings, if it is stated to be for -6 AN hose, than it can either be used with the -6 AN hose, or just high pressure 3/8 hose?

Also, is there to be any concern with the hose by the exhaust?

Being in both high heat and freezing temps here in Jersey, if I bypass the trans lines in rad will the trans not get up to temp during the winter months? Or will I just have to let the truck warm up a bit when its cold out?

One more question, whats the easiest way to install a temp gauge tap in if using rubber or AN hose the whole length?

Thanks.

Re: Barbed fittings for transmission cooler lines?

Lots of questions, lol. Lets see if I can answer them all...

Just clarifying, with the 90 fittings, if it is stated to be for -6 AN hose, than it can either be used with the -6 AN hose, or just high pressure 3/8 hose?
I'm using high pressure oil resistant power steering/transmission cooler hose. With the -6 barbed fitting you can use any hose with a 3/8ths ID. The guy at Earls told me you don't need to run a clamp with these fittings but I'm throwing one on there anyway.

Also, is there to be any concern with the hose by the exhaust?
It's actually further away now because I have the 90 fittings angled up and to the rear, before they went straight forward and over the exhaust on their way to the radiator.

Being in both high heat and freezing temps here in Jersey, if I bypass the trans lines in rad will the trans not get up to temp during the winter months? Or will I just have to let the truck warm up a bit when its cold out?
I don't see it being a problem, the fluid heats up from friction inside the transmission itself. I do not know the answer to that question though, sorry.

One more question, whats the easiest way to install a temp gauge tap in if using rubber or AN hose the whole length?
I am not using rubber hose the entire length back to the cooler. I'm using short rubber hoses from the fittings to the body, then running hard lines down the transmission tunnel towards the rear seat, in through the floor under the rear seat on the passenger side of the tunnel, and along the floor back towards the cooler. then up the D pillar to another set of short rubber hoses going into the trans cooler. I am putting the sending unit for the gauge into a 1/4" pipe T with two 3/8ths hose barbs on it, and the sender into a 1/8th pipe to 1/4 pipe adapter, then into the T. The gauge sender needs to be grounded, so I soldered a wire to the side of the T and put a ring terminal on the other end, so I could ground the T to the body. I'm going to put the T inline back by the cooler, on the inlet so I get the temp right before it goes in.

Thanks.

You're welcome hope this helped a little.. I'll update again once i get the hard lines bent up and installed, hopefully it will be later today.

Re: Barbed fittings for transmission cooler lines?

yes 3/8s steel hard line. I'm flaring the ends and double clamping the hose onto the line.

Re: Barbed fittings for transmission cooler lines?

I went to the Earl's retail store, the original store is ~5 miles from my house, I couldn't tell you how much the hose is.

Summit Racing sells Earl's fittings and the hose as well.

The temp gauge is simple, add a t fitting at the transmission.

Re: Barbed fittings for transmission cooler lines?

Nice mike! I have some leftover firesleeve for the lines by the exhaust if you can use it. ATF is pretty flammable, I seem to remember that most of the trucks that have burnt to the ground in the dez are from atf leaks.

If you can find a 9/16-17 threaded pipe fitting anywhere, it is really really damn close to m14x1.5. Note that I don't think such a thing exists, I just ran the calculations to convert to SAE
Do not use tapered pipe threads for this, the case is cast aluminum and will crack.

Yeah, I've heard that about those fittings too - not needing a hose clamp. Never been brave enough to run without the clamp though!

We can attest to the ATF being flammable. And it doesn't take much to set it off. And the big pool on the ground under the car will be burning too.
