I've decided to go with a transmission with 98k miles on it from a 99 Riviera for a little more money.
'll look it over and see how things look before installation. Hopefully it is in good shape! I've started a list of things to get off the car and I'll include your suggestions. The car it is coming from looks to be in better shape than the other one so hopefully it means they took better care of it
