Tko500??

[Blown 5.0]

I actually think our problem is the pressure plate not letting the clutch release, Centerforce pressure plates are designed to apply more load as engine rpm and load goes up. (hence the flyweights on the diaphram), Third may be the the hardest gear to shift due to countershaft speed, mainshaft speed, ect. I dont know this for sure but i do think it has a bearing on the whole picture of things. And as far as teck support in my opinion there is none, As i stated before termec never admitted a problem but they sent us the shift fingers and a install kit. ( after a lot of phone calls and i threatned to video a pass with the third going into the neutral posotion , and put it on the web) But this did fix the neutral third, Now it just wont go into third under power. ( spray and boost, will take with just the boost) But like i say i think its the pressure plate. (its just doing what it was designed to do) .For the money i think there are better choices out there. In my opnion the 600 is one case that you dont get what you pay for.

To counter your arguement, I will ask you how you can blame the clutch when the 1-2 and 3-4 shifts aren't an issue?

I'm inclined to agree. Although I'm open to all arguments...but at the moment, I'm leaning with Brian.

The clutch I'm using is a RAM 900 hybrid that Bob Hanlon suggested to use with the TKO. And it seems weird that it would be clutch related when so many with this same problem all have different clutch set-ups.

ok my vibration dissapeared after breakin period....if yall dont know yet i installed my tremec 2 weeks ago...its auesome and shifts great...i have a king cobra clutch with the pro tower 5.0 shifter took it to the track sunday and missed 2nd gear 1 time because of operator error. that missed gear makes us 1 for 1 04350Z...

Interesting thread over on Corral.net with an interesting response from someone that appears to be in-the-know about TKO's.

The TKO-600 is rated by Tremec for 600hp/600ft/lbs of CONTINUOUS(not peak) power/torque.
I have heard of instances where guys cannot hit the 2nd to 3rd shift at high rpm(above 5800-6000rpm)
I have one in my '90LX with a 347 stroker and a Kenne Bell S/C and it dynoed at 630RWHP and I haven't broke it yet.
The G-Force tranny is an EXCELLENT choice for high horsepower applications that are doing alot of track passes and are running slicks. If this fits your description, than DO NOT try and run a "stock" TKO.
There are several companies out there, Promotion Performance just to name 1, that does "Pro-shift" the TKO and makes it capable of handling alot more power and high RPM shifting. Their prepped TKO's are in Mustangs everywhere and hold several NMRA records.
I pulled a T5 out of my '90 and replaced it with a TKO. There is no comparison.
I have been working Tech Support here for over 2 years and can say without hesitation, I have never heard of or seen a broken case on a TKO. That's not to say someone somewhere didn't have it happen to them, just that I have never seen it.
If you are running street tires and power in the 500-600 hp range, the TKO will be fine for you. The minute you want to switch up to slicks and shifts above 6000rpm, you need to look at getting the TKO prepped or go with G-Force.

It's good to finally hear someone admit to the inherent inability for stock TKO's to shift above 5800 RPM.

That would've been nice to know before I wasted my money on this heavy piece of junk.

interesting.

I wonder what their response would be about the vibrations that the new tko's seem to have

It has to do with which parts are rotating in the trans.
The pressure plate's ability to react greatly affects the shiftability at RPM. And in particular, the counterweights on a CF are not helping your high-RPM shift issue.

Believe it or not, I have seen peoples shifting troubles dissapear with a clutch swap.

Doesn't explain my misses though. Mine were on the street with drag radials and 5800 or less shifts.

But, as I said, I actually hit third about half the time. So mine might possibly just be the weird location of third that is causing me to subconsciously miss it. It seems much closer to first than usual to me. When I force myself to think about it, I actually can hit it.

You can't honestly tell me that you think the counterweights are keeping my clutch engaged even when the pedal is pushed all the way in.

The only way that would be possible is if the fingers were to bend - which is not at all possible.... at least, not without permanent damage.

Just got off the phone with this guy:
http://quicklx.stangnet.com/

He has a Tremec 600 and a SPEC stage 3. He leaves at 6600 and takes it over 7000 between shifts. 10.65 @ 127 No problems.

The fingers bend anyway, every time you depress the pedal. Why not just a little more I know it's not the entire problem; but it ain't helping.
