700R4/4L60E SmartShell Assembly.

One of the steel bars was bent on the end. I had to straighten it out with a hammer.

The product was a perfect fit!

Autoplicity agent was very helpful over the phone. He answered all my questions & even did some research to make me feel comfortable I was getting the appropriate parts I needed for my car. I was very pleased & will shop Autoplicity again.

Everything went smoothly, love the prices and the ease of transaction, hope to buy from you real soon, Nice people.
