Help your needed
2007 TL-S
Just came back to garage and noticed drops of red oil - trans one.
When opened the hood, noticed coolant reservoir tank was full and overflowed with red oil. The oil splashed over the top of the radiator and the tank.
The AT dipstick is clear - no oil. Quite strange as no dashboard indicator went on. Probably it flushed just before stop, as we smelt oil.
Not sure if it is important, but 2-3 weeks ago I noticed several drops of coolant on the floor but as suddenly as it appeared, it stopped.
I am in Poland and the parts are not available here. The freight takes some time and need to solve it by one order.
The help I need is what are the exact parts numbers I should buy to fix it.
Already know that this is probably the radiator. However I also have found such indication: 'On my 07 TLS, the line that connects the heat exchanger to the radiator had cracked and thus mixing the coolant with the trans fluid.'.

Rock Auto Is quite nice - I am collecting the magnets they add to their shipments 😊
They haven't got the Denso radiators 3 weeks ago in their offer. Thanks.
I am just curious about this:
'On my 07 TLS, the line that connects the heat exchanger to the radiator had cracked and thus mixing the coolant with the trans fluid'
I can see there is some kind of double metal tube in the bottom of radiator area.
