VX transmission cooler lines and rad fittings

[Fu Manchu]

I was planning on using a -6AN quick connect.

Maybe these? Would the male quick connect barb thread into the radiator the same place as the one @Immortality showed in the photo?

I know these are for fuel lines but they seem to be the same size as the trans lines.

No, that's a male AN fitting on the screw side, you need an NPT to barb (AFAIK Commodore radiator bungs are NPT), or a female JIC to barb fitting to put it onto the existing fitting.

So you would need something like this: https://www.efisolutions.com.au/male-1-8-npt-to-5-16-barb-black

Once you change to AN fittings is basically quick disconnect regardless.

Interesting post from EYY saying they're NPS fittings, probably why they have o-rings: https://forums.justcommodores.com.au/threads/trans-line-hose-fittings.247588/#post-2769757

For the ease of getting the NTP fitting and some teflon tape I'd say it's worth a go.

I love EFI solutions. So much great kit.

I have a after market trans cooler set up on my VX SS that I did myself, similar line fittings as the V6 as they use the same trans (4L60e) mine is set up like this ...

From trans >radiator inlet (bottom fitting of radiator) > radiator outlet (top fitting) then the rubber line is cut in the middle and a barb fitting> -8 AN is used then a -8 union is used to join to the after market hose -8 that of course goes to the cooler then the outlet of cooler hose is routed back to the engine bay where it's connected to the other side of the cut hose via another barb> -8 AN fitting + union, it's been on for 6 years no leaks.

You have to heat up the hose with a heat gun and push like hell to get the barb on.....and when it's on its on good so don't worry it's a strong connection, if you want photo's I can supply some.

Also just have to add if you use a transcooler try not to bypass the radiator altogether as the water as it gets up to temp helps the trans get up to temp quicker.

Just to clarify, that was for the fittings that go into the trans case
