transmission oil cooler modification

[alpom]

hello,
i have leaking problems with my transmission oil cooler. its leaking from the right side of the transmission where it hookup. i just changed the seal and its still leaking... too much to drive it. The metal from the cooler part seem damaged... do i need to change the cooler or is it possible to only change the "coupler" that goes into the trany. is there a way i can modify this part so it doesnt leak anymore? like a banjo bolt or something like that.

thanks for the answers guys.

it looks like it's just a push-fit with a bracket, so you can replace the o-ring.

o ring is brand new

maybe you need a bigger o-ring?

I had a request to make some hose fitting adapters and need the dimensions off stock fitting ends



A=Diameter
B=Diameter of retaining groove
C=Width of retaining groove
D=Dimension for outside of retaining groove to end of Dia. A

Same issue on mine. One fitting was damaged and O rings wouldn't help. fortunately one Rennlister had one he was just going to toss, so He's sending it to me. PO had tried with silicone seal to staunch the leak but it was a bust. It'll be good to get the cooler, so I can mark this issue of my list of things still needed to complete before the cars road worthy again. Porsche want's nearly $900 for these things. Not surprising since they want $42 for a $3.50 wheel bearing inner seal.

Still looking for the dimensions posted below to make some custom fittings.

JUst a thought re tap re thread and americanize it then the fittings are much easier to get if u can. just a suggestion. u can go bigger not smaller. but u can also create a nightmare

The fitting into the trans is an internal o-ring seal. The stock tube fitting presses into the ID of the casting sealing on the o ring then the U shaped flange keeps it from blowing out. A similar concept is used on AC fittings.

This relates to why I am looking for the dimensions to make some adapters. I don't have a turbo trans or a 951 but do have cad skills and machining capabilities... I'll buy someones old fittings that slip into trans if nobody has calipers to measure or time to get these dimensions.
