Mine came with one, but only because the owner had disconnected the existing
radiator cooler. I re-connected the radiator one (he had wrong fittings when
hechanged radiator) and kept the outboard add-on. I have no way of measuring
ATF temp but it couldn't hurt. Still, if I had no add-on, I think I'd prefer
adding a bigger oil cooler before doing the ATF cooler. Those high oil temps
scare me but Brian is probably right, they're just the result of bad
sensor/gauge selection by Peugeot. Pug's factory oil cooler is in a bad
location for air flow AND it's smaller than most I've seen on turbo cars. Just
my 2cents. Bob.
