What I've gathered from all of this is that the trans needs a rebuild...I'm wondering how much work rebuilding it myself would be. I've replaced both half axles before and a bunch of other work but never tackled a transmission other than in a class years ago. Any recommendations on rebuild kits or about how much it will run to rebuild this myself. The car is stock and I'm just looking to get some more mileage out of it since it has all new suspension, brakes, fuel pump, exhaust, etc...I'm really not willing to pay 2000+ on a car that's over 12 years old with 170,000 miles. Any advice is appreciated.
