i just got my truck back after a $1700 trans rebuild. All the shop did was rebuild the trans, replace the starter, and change small parts like the doenut to make it quiet. the problem is when i was driving it home, after it drove fine for 15 min, i was stoped at a light and when the light changed i hit the gas and heard a loud crack noise. the crack nosie was followed by griding as i accellerated and as i slowed down the grinding got louder. I came to a stop and changed hit the 4X4 button and idled it (griding) to a parking lot and waited for the tow truck. car won't move in rear wheel drive while waiting i noticed the car moves when it's in park, when the tow truck declined the suburban to roll it up i saw all this fluid gush out the rear end. I'm totally tripping now b/c i've already drooped 1700 and not sure if i need to spend more on it. i'm almost wishing right now the shop screwed something up, and will repair this at no charge. Any thoughts, would the trans rebuild affect it? I had the trans rebuilt b/c it wouldn't shift into 3rd and 4th. everything else in the truck worked fine. it has about 100K miles. Also, i love the truck and want to keep it longer so any insight would be great thanks. the same shop has the truck now and will call me tommorow but want to be ready to argue if i need to.
