I just noticed the other day that the coolent tank had a pink oily look to it so I took it out and drained it. I then took off the rad cap and noticed that the coolent looked like a strawberry milkshake. Im guessing the trans cooler sprung a leak in there and is mixing. However I didnt notice any evidence of coolent on the tranny dipstick. So im hoping its a one way leak.

Does this sound right?

Is the car still safe to drive for a few weeks till I can get a new rad?

and finally is it easier to just put a small tranny cooler and plug holes in the old rad or should I just change the rad??

Thanks.
Martin.
