I got in a collision today, 99 tahoe 4 door, ls with tow package. Moderately low speed but enough to push the front end into the radiator (i guess the crumple zone). Well first thing i noticed was trany fluid everywhere. I thought i was screwed i figured the motor got pushed into the transmission. But i noticed it was coming out the bottom of the radiator. I pourd some fluid in it and got it home. But what could be up front that could be leaking transmision fluid? Does the transmision fluid rout through the radiator?

 

Probably has the tranny cooler inside one of the radiator tanks, usually on the psgr side. Do you see two lines connected to the radiator tank?

 

the tanny cooling lines on the radiator, Or it came out of your dipstick. Also some people put transmission fluid in the powersteering pump

 

thats exactly where its coming from the passenger side. So does this come on all tahoes? I belive it had a tow package, my first thought when i seen the tranny fluid was man ive destroyed something. But then i rememberd it had a tow package. Has the g80 rear end. So i figured it was a tranny cooler that was leaking. And yea its got some metal lines going into the radiator. Sucks i just got this thing and i really liked it. I may start pulling everything off thats bolted on and get a better look to see if i bent the frame. There was a line of cars and i wasnt paying attention and one stopped up ahead and by the time i knew what was going on i hit the brakes but it was too late. The vehicle i hit was a toyota Sequia and it recived very little damage, while my chevy hood was bent up and whole whole front end was smashed. speeds were around 20. I had a choice of a fire hydrant and a ditch or the Big *** Sequia, I probaly should have taken out the hydrant.

 

If your tranny cooler is in the radiator then all you need is a new radiator, I would take a good look at your tranny fluid and make sure that if the blatter inside the the radiator blew apart then it would mix you coolant and your transmission fluid, to be safe you should get a full coolant flush and transmission flush after fixing the radiator.
