    Transmission cooler leak

    Recently I had the transmission cooler line detach from the radiator (right after turning 150K)and puke strawberry milkshake all over my driveway, how much life can I expect out of my transmission now that its all fixed? The morning of the day it happened I got a low coolant warning, but took the car to work anyways (15 minutes away) with the intention of refilling it once I was out of work. As soon as I got out of work I took it slowly home, but upon entering my driveway I got the "engine hot shut off ac" warning on my radio and shut the car off right then and there, opened up the hood and it was puking strawberry milkshake all over the ground. Eventually I got it all fixed (radiator and lines replaced, engine cooling system cleaned, tranny flushed many times, then run through a machine to pump all the milky crap out) and it seems to drive like a champ. I would like to add that i didn't drive it at all after the blowout, I just let it bleed itself out overnight. How much life can I expect out of the transmission? It seems to drive fine now, but should i start looking into getting another car??

    Re: Transmission cooler leak

    no way of saying for sure. It all depends if coolant got into the transmission, how much and how long it drove this way. one can assume that the day you got the coolant leak was the first time the coolant began to possibly mix with the transmission fluid. If so you are probably ok, but if there was coolant being siphoned prior to this then that may be different. I just finished installing an external cooler to prevent this very thing from happening to me. See link below.
