TKO 500/600 clutchquestions

99LS1 · 07-15-2007, 11:18 AM

I'm looking at swapping to a TKO 500 or 600 soon. I wasn't sure if the 600 would be overkill, but it's not much more to get the 600. The setup isn't going to be too wild. Best case scenario is a 383c stroker on spray.

This has probably been covered, but what's a good clutch/flywheel setup? I don't mind a heavy clutch but something comparable to an 03/04 cobra feel would be fine.

My SPEC 3+ is lighter than my stock clutch was, and will hold way more power than this car will ever make.

If you are going to buy one or the other I would go ahead and buy the 600. I had one in my 97 cobra and had no problems at all with it.

I wouldn't buy either. I think 97cobrasvt is the only person that had one that wasn't junk

if you buy a tremec...go old school and get a original tko....

Yeah, mine is a piece of crap as far as shifting goes.

However, if you decide you want one, you'll want to look into the gear ratios since they are different between the 500 and the 600. You may want the 500 since it will get that heavy car off the line better.

Here's some useful information on various transmission ratios:

Also, if you go with the 600, you'll have to buy a clutch that comes in a 26-spline disc.

The gear ratios and input shaft options are the only real differences between the 500 and 600. The 500 having a 3.35 or so first gear and the 600 has a 2.95 or something close. Now, the 500 comes in 10-spline (stock-type) or 26-spline input shafts. The 600 only comes in 26-spline.

The 10-spline is good up to about 500hp reliably. The 26-spline is good for more like 1000...well beyond the rest of the trans.

Clutch from SPEC is the same price, either 10-spline or 26-spline...some other brands have a price difference between splines, but they shoudln't; Nothing else is different except for the center hub of the disk.

If you decide to go with a 500, because of the ratios, definitely don't waste time with the 10-spline, since it's about the same cost and the clutch is the same, except for the disk hub.

Now I'm surprised by the responses, especially Italian's and Lee's. I thought T5's were notorious for breaking when you start putting down power. I figured people would like their tremecs.

Maybe I should just back up and get some opinions since I know very little about ford manual trans.

The mustang has a 3.90 rearend and weighs ~3800lbs. It needs a 5spd. I can't see making much over 400whp/ftlbs and I doubt I'll speed shift it much, but I'd rather buy something that's built to last and leave it alone. What are some good options for swapping to a manual? Some variant of a T5? Or some other option I'm not aware of?

tremec 3550...you can get them for a fair price on the corral.

or if you want i just may have another tko for sale soon

99LS1 · 07-15-2007, 07:37 PM

Unless I know the person I'm real hesitant to buy a used one. I've had a lot of problems from buying used ones in the past.

I'm interested in hearing some T5 vs 500/600. I'm assuming Italian couldn't get a T5 to work behind his 418 if he went with a tremec. But it sounds like he doesn't like it either.
