Owner of this supercharge caddy was having some hard shift concerns. After test driving the car a knew there was some damage inside the transmission. This car had some getting up and go for it to be a Cadillac.

During the test drive the car would slip between 3-4 shifts and and would slam into gear from 5-6 shift. After the rebuild, I test drove the car and it was still slamming into gear. The owner mention that he did some tuning to the car transmission. So once I reset all the settings back to the default settings this car ran like a champ.

When open the transmission the 1-2-3-4 5-r drum needed to be replaced and the 4-5-6 drum piston and damper was destroy.

I upgraded both drums and a Sonnax after market setup for the 4-5-6 drum.
