Not unless you send it to Yank, it's a sealed unit and you need some sort of high powered plasma cutter to get it open. Even then unless you know what you're looking at you might not be able to tell its condition easily.

I agree with the others that something's fishy at that price. Caveat emptor.

I just put a Yank SS4000 in my 98 Z28. First time I really drove it was today. It defiantly feels different. It's loose for sure, but I'm sure the 2.73 highway gear isn't helping with it at low speeds. Still haven't had it tuned so I didn't really jump on it, but I took off and let it shift under half-three quarter throttle a few times and it felt good. For 150 I'd give it a shot. Paid 800 for mine.

I bought mine used for around that price, but eventually had to send it back to get it rebuilt. I say buy it and have Yank look at it, cause you'll still come out cheaper in the long run.
