I am contemplating deleting the torque management on my car and was wondering if anyone can tell me from experience if by deleting the torque management whether or not it will shorten the life of the stock 4L60E tranny?

The tranny sucks anyway. Mine went with TM still in in only 1 racing season. Now it's gone and completely rebuilt so I am hoping for better results. Do u have a shift kit? If not I wouldn't remove it. Save that for when u need custom tuning and then they can do that also. Just my .02

I do not have a shift kit, nor do I want one. I have an ST-3500 and keep the shift firmness with the HPP at 0% because the tranny goes to 100% firmness under full throttle anyway. I was thinking that if I removed TM that I could shave off about .2 off of my ET. However, I guess I need to weigh the trade off in ET reduction vs. tranny life.

Well Chuck at FLP recommends torque management be deleted with there Level IV, so I am not so sure that torque management is a good thing.

Matt, yes the stock strany life will be shortened by deleting the TM.

Sorry.

And don't expect to drop 2 tenths just from removing it.

What would be a realistic drop in ET if TM were deleted?

I had TM taken out with Ed Wright tuning.
NO ET change, but it shifts real nice now <img src="graemlins/gr_cheers.gif" border="0" alt="[cheers]" />

Dave,

How many miles have you driven your car since you had the TM taken out? Any adverse effects?

Has anyone proved that removing TM shortens tranny life? Has GM ever used TM in their cars before 1999? I never heard of it in the third gen cars or the 4th gen cars until 1999 model year. So if it was so necessary why wasn't it used all those other years? I think it's just GM being over cautious.

Yes, deleting tq. mgt. will shorten the life of the trans. With it deleted, you are getting full power on the shifts vs. having tons of timing pulled out on the shifts to reduce the power. With as much as I'm planning on racing this season, the stock trans is on borrowed time IMO anyways. That's why an FLP level IV 4L60E is in my future. <img src="gr_stretch.gif" border="0">

Some of the '01s have shown a .1 drop in ET from removing TM. I'm not sure what GM did in the '01s but those cars seem to be hurt by it more than the '98 - 00s.

I've had Ed Wright tuning for about 6 months/3,000 miles. 1998 Z28 A4/2.73 w/street tires, lid/SLP cold air, catback, ASP crank pulley. 13.3s @ 105+ mph with HPP3 tuning. Changed PCMs at the track, still the same. I autotap & can see the TM is gone w/ Ed Wright PCM & it's so much nicer on the street. A4 shifts like a 'normal' years past trans. I don't think that it will hurt the A4 as it was designed years ago, when TM wasn't around. Ed Wright part throttle tuning is SUPER. My 2.73/A4 combo. has much better throttle off idle 'tip in' response, & low speed driving is so much better. Drives the way GM should've but couldn't because of EPA crap. Don't know how Ed gets away with it, he must have found some legal loop-hole. Glad he did <img src="graemlins/gr_cheers.gif" border="0" alt="[cheers]" />

02BlackWS6,

GM went with TM as it saves a lot of warrenty work. It's just high-tech computer/software that just became of age just a few years back. It just didn't exist years ago. Just thing of all the stuff we have today that just wasn't around when the 3rd gen cars came to be. So, I guess the answer to your question is you just can't do what you don't got. <img src="graemlins/gr_cheers.gif" border="0" alt="[cheers]" />

Dave,

My question wasn't about why GM didn't use TM in the past. I know that it didn't exist back in the day. My question is since TM didn't exist then why didn't trannys break all the time? So i think that TM isn't real needed. Auto's have been used in muscle cars since the 60's and i don't really remember autos breaking that often. And the 60's and early 70's cars made more flywheel power than we do. So i think that GM is being alittle over catious. Which is cool, cause they are making our cars more reliable. Just my .02

Yes, deleting Tm will make your tranny go sooner then you would like. When you delete it, I was told that your tranny will heat up alot faster and then it will just go on you. It sucks but what can you do if you want to go faster then it is a must to tune your car and get a better tranny it sucks but what can you do. I have TM right now and every case is different. I was told as long as you keep the tranny under 200 degrees you should be safe for a while. Sucks are cars did not come with a th400. Nothing will blow up that trans. <img src="graemlins/gr_guns.gif" border="0" alt="[guns]" /> TH400 <img src="graemlins/gr_judge.gif" border="0" alt="[judgement]" />

I thought our trannys were an electronic version of the TH400.

I want to delete thats **** just b/c it's annoying as hell at part throttle! Car falls on it's face at 1/4 throttle just driving around on the 1-2 shift. Also, I would think it has to make a big difference. On some cars(mine), the nose dips on the 2-3 shift. From what I've experienced driving m6's, somebody who can't shift fast enought o keepthe nose from dropping, goes alot slower <img src="gr_eek2.gif" border="0">
I wouldn't fork out $500 for it though <img src="images/icons/rolleyes.gif" border="0">

Nope, not even close. The TH400 is a 3 speed non overdrive tranny built totally different than the 4L60E in the f-bodies.

Yes, removing TM from my PCM raised my trans temp quite a bit after a few WOT upshifts (about 10 to 15 degrees). Why did it raise the temps? Because I was seeing negative 5 degrees of timing on WOT upshifts and now I’m getting 28+. The extra 30/40HP that I’ve gained during the upshift is harder on the tranny hence the higher temps. I don’t really care though, as I’m getting a new trans in a couple of months anyway. I’d guess I probably gained a tenth or so with it gone. My car was really falling on it’s face during the upshifts before, now it just charges through.

If you can keep the temps under 200 and all should be fine for the most part. Heat kills trannies.
