New Converter for the Yukon Well I made the switch.....I still love the Yank in the camaro but decided to give circle d a shot for the yukon. I wanted something pretty tame so I could tow and what not. Settled on the 2A 3-3200k 11" model. I'm sure I will be pleased with it. I'm going to combine this with LTs and full 3 inch exhaust, AWD delete, and a built 4L60e (mine is showing its age). Circle D response time was second to none and it shipped really quick.

Actually thats kinda a good question. Anytime you can stall the engine up a little higher before you "drive" the transmission gives you more pop out of the hole. The difference is sorta like if I told you to punch the wall but only let you get a 6 inch pull back vs a 2 foot, which punch would be harder? We use high stall clutch kits in our ATVs for mud riding as well to get big mud tires spinning in thick mud. So for towing the truck will be able to get the load moving quicker, and you wont be waiting for a powerband to help acceleration, the converter will keep you at or near the powerband for better overall performance. The downside is heat. Hot summer, stop and go traffic, its gonna be hard to manage transmission temp. The good thing is all my towing is mostly done on the hwy so that's not a huge concern. Also, this truck is more of a daily for me, just a commuter, I might hook the car hauler up a few times in a year.

Finally got this thing installed and took it for a test drive. Truck moves along from a stop at 2k rpms, and it flashes to exactly 3k from a dead stop. Its not loose or sloppy at all, feels just right. Two thumbs up circle d.

Heres the full install thread for those who want to read it. Converter clearance was a smidge over 1/8" so I ran it with no shims.

With my yank ss4k (9 inch billet front) I had to shim, probably would have been ok without but I wanted it right. The right thing to do is measure, but I'm confident that most likely with the bigger converters you won't need to shim. Check anyway so YOU can have confidence in your install.
