Tremec TKO 500 Prices

I would fork out the extra cash and get the 600 myself.

500...600...who gives a *****. LOL just kidding, but seriously I really don't think there is much difference between the 500 and 600 besides the 1st gear ratio, which is a personal preference. I bought my 500 from http://www.ddperformance.com/. I believe it was around $1,700 at the time. I opted for the 26 spline input shaft, you will not be disappointed with that tranny or that bunch of guys.

I don't understand why people think the 600 is better, I guess because it has a higher number. The 500 has a lower first gear ratio which is just slightly higher than the stock T5, and you can get a 500 and use a stock style clutch while with the 600, you have to get at least a different fricion disc because it only comes in 26-spline. It is said that the 600 is stronger than the 500 but that is because of the input shaft on the 600 only comes in 26-spline, but with the 26-spline on the 500, they are equal. Just wanted to help clear that up.

D&D seems to be the #1 for the TKO's.

I would call Liberty and G-force and see what they have to offer for your 3550, might be able to get the 3550 rebuilt stronger, and better for less.

Good find, bell housing is wrong but looks like our man already has one if a 3550 is what he has right now. Don't forget you'll have to find a 31 spline slip yoke for the TKO, the 3550 was the same as the T5 wasn't it?
