Looking for PN of transmission fluid cooler tube

I have 2004 FX45, I found out that one of fluid cooler tube (supply line from transmission to cooler inlet hose) is slightly collapsed from what appears to be a hit by something on the road the car had run over and was too high.

I need the part number for this tube - see picture below - and where I can get it from, I tried infinitipartsusa but they do not have this listed, I tried other sites but no success. Any help will be appreciated.

I posted the same thread on another forum, and I got the answer and it was on http://parts.infinitiusa.com, where any part number can be found on their eStore, I need to improve my online searching skills!.

Anyway, the part cost (one tube) was 55$, but after a lot of research, I fixed the old tube with steel compression fittings.

The tube is basically 3/8" in size, and so is the hose connecting it to the cooler, as you see in the picture, the tube is damaged close to the hose connection, so obviously I was unable to cut out the damaged part and reconnect tubes, I actually had to cut out the entire piece in the picture along with the hose connection.

So I bought the following:

1) 3/8 compression fitting with ferrule x 3/8" NPT female connection (for first time use, you need to tighten very well for the ferrule to sit in place in such a way it is snug and can no longer move, you need to unscrew and check that is physically the case, this is critical for the integrity of the connection and to prevent leaks).
2) 3/8" NPT male connection x 3/8" clamp style hose connection

You probably can find a single piece of fitting with both required connections so you won't need to crossover, I did not have many choices in my case.

All in all was for less than 20$. After installation I took the car for a quick trip and came back to check on any leaks, none found and all is as good as new.

I hope this helps others who might have a similar issue with any of the lines (brake, cooling, fuel ...etc) as this can save you some money that you could keep for better use.

Impressive DIY. Did you notice any issues from the kinked tube? Or did you just happen to see it when under the car?

I saw it when I was under the car changing the transmission fluid.

There is currently an improvement in shifting but I guess it is because of the new fluid. The only problem that could have caused and I was unable to notice is a restriction in the fluid flow around the transmission, so less cooled fluid coming through. Because this is the supply line, i am lucky the hose is downstream of the damage otherwise it could have bursted maybe due to pressure build up?

You can image a tube that is 3/8" in size by design comes down to probably less than half of that, it it can't be right and I am glad to have discovered it and fixed it.

Probably it worth mentioning that, as I was tracking the damaged tube all the way to the transmission, I saw that the crank shaft going forward to the front axle drive is right in the way, the end fitting is right behind it in such a way that it will be impossible to remove without dismantling the crank shaft. Replacing the old tube would have been a hell of a long and agonizing job.
