I'm about to get my car tuned, and was wondering if I should remove torque management (or just reduce it, for that matter). A couple guys I have talked to say that it can be pretty hard on the tranny. They recommend getting a shift kit and vette servo instead. However, I don't want to spend that kind cash right now, and since I am doing the tune, I figured why not.

The car is a DD and doesn't usually get driven too hard. Eventually, it will get a stall, but not for a couple years, and I figured I would do a shift kit then, since they will be in the tranny anyways.

So is deleting/reducing TM that bad? Should I not do anything to it, just reduce it, or delete it. Mods are in sig.

My TM is reduced a lot, so much it's probably not effective.
Reducing or deleting TM or getting a shift kit are two totally different things.

I have a transgo shift kit, my car already had the vette servo and yours should too. I set my shift kit up different than what the instructions say.
I like extra firm shifts. The best part about tuning yourself is that you can set the trans to shift firm mechanically then tune it to shift soft at light throttle and firm at high throttle.
Maybe thats off topic.

To answer your question....you'll hardly notice a difference if you get TM tuned out of a stock trans. I hit TM a few times when stock and the car fell flat on it's face.
With a shift kit you will hit TM more often, so if you plan on getting one in the future I would tune TM out to save you from doing it later.

My car will now spin through second and bark third at 82 mph, if it breaks the trans, I guess I'll rebuild it and go a little more mild, I'm not too worried about it really.

no shift kit here but had the car tuned the first time 2 years ago, and 25k miles ago, torque management was turned off completely then, knock on wood no problems with tranny. The tranny shifts hard, normal driving feels the same, with 3.73's lays rubber well into 3rd. It goes to the track a few times a year, and driven pretty hard. Just delete it

If you get a stall, delete torque management or at least have it lessened.

But DO NOT get a shift kit AND raise line pressure for your shifts with tuning. That will blow a tranny in no time. Do one or the other. A shift kit is a physical way to make the tranny shift firmer while tuning is the electronic way to do it.

That's what I wanted to hear. Normal driving at light throttle, firm shifts at WOT.

I will retune if I do a stall (I will prolly wait to do engine/trans mods all together, just to save on tuning expense).

The thing about the transgo shift kit is that it doesn't just give you firm shifts.
It also converts the pwm tcc apply to regular apply. In other words it does not pulse the apply and let the tcc get hot (if it happens under load) it just applies it, it will feel like another upshift.
It also lets you hold it in any gear at any rpm without automatically upshifting.
And a few other things.
I found a lot of stuff in my 2002 SS trans to be close to the same as what was in the shift kit, like feed holes to drill were already the same size and a few other things.

I think I told you this before that third gear needs help, the right way to fix it would be to take the trans apart and at least reduce the clearance. But you can get away with making the feed hole bigger than what the kit recommends. The goal should be to get third to apply as quick as possible. The kit also comes with a bigger boost valve to increase line pressure.

Then with the shift kit installed it will be capable of shifting quicker but won't because the vcm is programmed with long shift durations. So you then need to shorten the shift durations at higher throttle positions though VCM tuning.
After you shorten those the trans will feel like it's shifting too early so you have to program the shift points vs mph.
The only thing done to my trans is a shift kit with a few of my own mods, VCM tuning to the TM, the shift duration (or shift time vs torque as they call it) and shift speed vs tps%.

Delete TM, but don't jack with a shift kit. Your tranny will still run for a long time.
