I have what seems to be oil leaking from a sealed line that runs into the radiator, at the bottom.

Usually transmission cooler lines run to the radiator.

The fluid coming out is not tranny fluid.

Its not leaking bad.

Does anyone have a parts diagram for the oil system?

 

I revert my statement, I looked at it wrong. That line is leaking transmission fluid. It is not bad leak.

I do need it fixed, fast, of coarse.

This is what I need, a part number for the cooler line, and an alternative fluid I may use to top it up.

I have access to equipment to put fluid in it and check the level.

 

Try gaudin jaguar's parts system online if you havent't installed your own jaguar elect parts catalog. Buy the zf lifeguard 6 from online by the quart, or try VW for the same fluid.
