Hi I have an 2004 Chevy avalanche 1500 5.3l. Vortec and all together it's a great vehicle except for the fact that the front seats don't recline all the way but that is the least of my dismay. What I really and never will ever really understand is how anyone in there right mind would OK the whole transmission lines running to the radiator to for cooling purposes. Now I know the design has been around for a long time and never had an issue with it untilI bought the avalanche. Then one day the radiator decides to take a **** which was an overall easy and cheap fix... But what has really just pissed me off was now the trans is screwed up because water mixed with Tranny fluid and left me with $1800.00+ repair bill. WOW now it's like driving a 3 on the tree automatic cuz 3rd is gone and the rpm's spike just after the passing gear and it remains in 3000rpm on city streets. Anyway can anyone help since I'm not made of money it would be much appreciated. Thanks
