Tremec Question

[tunedin302]

I am trying to decide between a Tremec 600 and the T-56. Does anyone have any experience with the two. I like the idea of the 6th gear but will there be too many adjustments to make. I also saw an article that claimed you can't use an X-pipe w/ the t-56 and the trans tunnel has to be hammered out to fit the bell housing. Not to mention the DS has to be shortened 3/4". Bottom line: Is it worth it to get the T-56 over the TKO600? Anyone done this? Lastly, I was happy with ratio of the 1st gear of the stock t-5 and my 3:55 rear. Is this going to change signifigantly to the point where I will have to change the rearend gear ratio? Thanks.

My bro just mulled the same question. The T-56, although it has 6 gears, the top 2 are overdrive gears. So 5th is overdrive, and 6th is over-overdrive. Kinda pointless unless you get it geared so that you have 5 speed gears and 1 overdrive gear.

The sweet thing about the TK0600 is that the overdrive gear is like 0.64 (at least his was) compared to the T-56's 0.62 (I think it's 0.62 on a mustang). So it seems pointless to go with the T-56 when you need all that extra work when the TKO600 will do everything the T-56 will do, minus that inbetween overdrive gear. Needless to say, he went with the TKO600.

the tko-600 1st gear is a little higher, i think they recommend at least a 3.73, thats what i have and its perfect for the 600. i think the t-56 would just be way too much work without any benifits over the 600.

TKO 500 all the way, way better gear ratio's. The ratio's are close to stock. No wimpy sub 3.00 first ratio for me!
