How Do I Know If I need a rebuild kit or a new torque converter? Or Something else?

I will Get The Corvette Servo And .500 Boost Valve With What ever i get.

My problem was written in my other thread titled "NOW WHAT"

 

If your tranny is bad you'll need a torque convertor too, the old one will be full of metal fragments. Unless you do the old trick of drilling a small hole on the mounting bolt side and flush it out, then tap it and install a small pipe plug.
My cousin didn't replace his at first b/c of money, he barely scraped up the $140 @ Advance Auto for a complete rebuild kit. But later ended up having to buy one with his next check anyways...

The only way to know for sure is too unbolt the tranny and slide it back or remove it and try a new convertor. Usually you can get a salvage one for $25-$30. If it works, drive it like that until you order a good stall convertor...

If you decide to rebuild it get the TCi video from Summit Racing, it's an excellent tool for rebuilding a 700r4..
