AN is AN as long as your tubing is good for your use. NPT Is NPT.

Those fittings are specifically for Earls power steering hose so I am going to say no without more information on the hose you are using. Most likely not. Get fitting designed for the specific hose you are using.

I would think the hose material is more important. Earls has lots of hoses for hot transmission oil :

Ya that 120 degree max temperature is not going to work for transmission lines. You can also buy nice hose and fitting kits for transmission lines on eBay.

Guess it's one step forward two steps backwards :( It's rough being a rookie mechanic.

Think I will need to drop the transmission to be able to get at the fittings to replace the hose.

I could not seem to find the right hose from Earls? Will this be a good choice for line and fittings?

I got a recommendation from a co-worker of a local Hydraulic Supply company that can make me up some overkill hoses so I don't have to worry about my abilities to make some. I can not take any road-trips if I worrying about hoses I've made.

OMG, That was not fun. To get at the fittings on the 4L65E I had to:

1. Remove the drive shaft
2. Un-Hook emergency brak cable.
3. Unbolt and drops the exhaust that I just had put in on Tuesday
4. Remove the Transmission Support
5. Lower the transmission inch by inch until I could get a wrench up in there and remove the fittings

And all that was probably easy compared to what it’s going to take to put it all back.

It’s a good thing I love this hobby.

Can someone also confirm, there is an upper and lower fitting on the 4L65E, does the upper fitting run via the hose to the upper fitting on the radiator?

The top line on the transmission is the return line.

That seems to make sense, fluid leaving bottom of the transmission is pushed to the top of the Radiator and then drains back to the top of the transmission.

The first hose listed at Earl's for transmission fluid is good to 350 degrees :

Thanks NashvilleCat but I decided to have a local shop make me up some lines that I don’t have to worry about.

That video seems to negate what was said above. Unless I misunderstood he said the outlet goes to the upper radiator port and back to the top trans port.

I simply cut a hole in the tunnel to get to the fittings and made an access panel when I put a 4L65E behind an LS2 in a 69
