Coolant/transmission
I have a 2006 CTS. Coolant was leaking a little so i
topped it off with the right caddie coolant. Had the
car for 4 weeks. Last night I was driving noticed a
lot of smoke coming out the temp gage was
normal. Pulled over popped the hood and coolant
was all over the bottom. The rad seemed fine then
so I try to go back home (wasn't that far) and the
car wouldn't drive forwerd or reverse and a green S
LIGHT came on,on the dash. So I don't know I
heard caddies have that safty thing where it
wouldn't let you drive to make it worse or if it's a
tranny problem? please help
