Oil cooler o rings for the transmission side are they same as the ones that fit the engine oil cooler lines?
Reason being I have a set for the engine oil cooler lines and I might need to replace the ones on the transmission on the drivers side cooler?
And if so how hard to replace them ?

Thanks

 

Removed the line and reconnected and leak resolved it looks like

 

I have a leak coming from my oil transmission cooler. Did you have to take the radiator out to change the seal at those connections?

 

no I just cleaned the quick connect areas and release them. You will leak at that point so put a catch pan under it. I had to source new o rings so I bought the kit from harbor freight

 

I think I need to replace my whole transmission oil cooler. Do I just add some more tranny fluid after? Or should I deal with a drain/flush.

 

This is what a lot of us did for the LS Swap: https://landroverforums.com/forum/di...zf4hp24-97300/
You should have a local fluids shop that can create a custom line for you using the original connectors that hook up to the trans radiator and the transmission.

 

After replacing the transmission oil cooler I no longer have a leak coming from the cooler or the connect points but I seem to be still leaking transmission oil from the front and driver side of the vehicle. Any ideas? Going to clean it all up and try to get a better idea of where it’s coming from but it’s hard as it only leaks when driving.
