i got my gtp with a blown motor. but the trans had been rebuilt 31 miles before motor went. anyways while replacing the motor i noticed the trans shop had completely bypassed the stock and added an aftermarket cooler only... i was kinda concerned about it and went down to the trans shop to ask about it and also about thier rebuilds. he said they do that with every trans they rebuild and never had one come back with a problem because of it, and that was good enough for me... they are the biggest, best, and most expensive trans shop in town from what everyone says... and the 3200 dollar reciept i have prooves it. paid 750 for whole car btw(cant stop braging about the deal i got, lol) i dont like how they put the plastic ties through the rad though so i snagged a bigger better one off a truck from pullapart that bolts in that i still need to install. or heck, maybe even run them in series if i can attach the current one better.
