Hey you guys. Im about to get a tune for my car since all the mods I want are done. The tuner asked me if I want to take off the torque management on my tranny or not. He said that it is a program GM put on A4 cars so that when it shifts the computer pulls timing and fuel so the there won't be too much stress on the tranny so it will last longer. Some people tells me is a good thing to have, and some people tells me that I don't need it. I was justwondering what are you guys opinion on if I should leave it alone or get rid of it. Any info or expierences are greatly appreciated. Thanks alot.

You're going to get differing opinions here too.
I took all my TM out. I don't see the purpose of modifying your engine to have more power only to have performance taken away from it to save the trans. GM did it to protect the stock trans, you need to upgrade the trans to make it hold up to the increase in power.

I'd get rid of it all, not go down a certain percentage. Modify the transmission to hold the power of the modified engine.

How big of a difference did it make? And what kind of mods do you have on your tranny?

You can pull all T.M or adjust the effects. It all depends on driving habits and the amount of power you are pushing.If going for a one time tune i would say, yes.
If you get into tuning you have the option of tailoring the T.M. to your wants.

Well my car would fall flat on it's face under certain driving conditions stock.
With the shift kit this would happen more often.

I have the TransGo 4L60E-HD2-B kit with a transgo seperator plate and holes the instructions have you drill drilled at .093, except 3rd and 4th at .106, stock vette type servo with one shim, kit comes with a .500 boost valve, aluminum 2nd accumulator with two washers (too many), pinless fwd accum piston, 3-4 and fwd hi-rev springs, borg warner high energy band and seven 3-4 frictions set to .030.
The car only has a lid and loudmouth exhaust. I'd imagine more mods would hit TM more often.
I got hp tuners and followed someones instructions on how to delete TM and they weren't complete. Run logs were showing a timing dip during shifts so i found all of it and got rid of everything.
Also changed the upshift and downshift points, set it to lock up only in fourth.

Hope all this rambling helps in some way.

after installing my transgo shift kit (in-car) i dropped 1.5 mph off of my 1/4 trap. i followed the full race/high stall instructions, and it shifts HARD. tqm took a very noticeable chunk out of my 1-2 shift and 2-3, as well. all of this was evident when i got it back to the track.

GREATWALLTA

I was told that I can also just eliminate some of the TM. Is it a better way to go or is it pointless? How much should I get rid of it if not all of it.

how much you want to remove is up to you. obviously the tranny can't hold the power of a STOCK ls1, hence the program. i see tqm as a crutch, with modding the tranny will go regardless, how long it lives is dependent on tqm. but i want to go fast (why else do you mod?) so i totally removed it. when the tranny goes i'll replace it with something better.

Would torque management make a difference on a vacuum modulated 4L60E?

TM will still pull spark in an attempt to limit torque.

I prefer to have it in, but on a short leash. I don't
have a big power motor but know that even a "small"
converter is liable to put shaft torque above the GM
rating.

Building a better trans is one option, but not a near
term option for everyone. You can always bust it
later.

Controlling the amount of timing pulled, can make
the car not "lay down". But it might take some
tries before you find a comfortable point where
the torque is mellowed yet acceptable.

Minimizing the shift duration will make any torque
cut less noticeable. Having a total torque cut for
a 0.4-second shift, that sucks. If the shift takes
0.1 sec then you might just miss it. A dead 0.4sec
shift adds an unnecessary 0.3xx sec to your quarter
mile time. But it doesn't need to be that long or
that dead, and then you -can- have it both ways.

On the other hand I tuned on an AWD truck once,
took out the TM and all was good. It would just
blaze all 4 right through the 1-2 shift (blower
truck). Then we got all fancy and put the TM
back in. This let the tires regain traction before
the shift completed and not too many days later
it was time for tranny #3. Bent some sprag or
other, right over. So there's things it'll keep from
happening, but at some point as you mod up the
old Indian joke is still going to not be so funny....

I also heard something about a Engine Torque Management on our cars too. Has any of you guys heard about it? Should I get rid of it too?

Torque mgmt. is for people who are scared too hurt their cars.I couldnt believe how much of a difference i felt going from out of box diablo tune (50-75%) to custom tune w/ torque mgmt fully removed. Car blazes the Nitto drs on the 1-2.

My car with a stock motor and bolt ons and a TCI 4000 stall would completely lay on it's face on the 2-3 shift due to torque management and it sucked and really slowed me down at the track. I got rid of it completely and now when I race it the car it shifts like it should. I'm sure I could have played with it and made it work better but I didn't want to.

I have another transmission if this one goes out but it's been fine for a while and all it is is a stock truck 4L60E.

Jimmy blue said it best buy putting it on a short leash. I ran for two years with no Torque Management. Now that I make more power I added some back in to prolong the life of the tranny.

Only Mods to my trans are stall, cooler and tuning. Keeping the transmission cool, getting rid of sloppy shifts(part thorttle and wot) and adding in just the right amount of TM will greatly improve transmission life. My trans now has 50k on it and its holding up quite well to weekly abuse at the track.

What year is your car? Torque management on 01's and 02's is much more agressive than previous years, and most guys who have those years get rid of it. I have an 00 and left it alone. Like Jimmy advised, I tuned the shift times down by 50%, and with the Transgo, I have quick firm shifts with none of that "lay down" caused by TM.
