I'm about to get a ms4 cam and I'm gonna get it tuned. There's one thing I can't make my mind up on! Should I cut the torque management all the way off or just reduce it to 25% or so. Anybody have problem with it off? thanks jsoh

whatever you do, it's not going to matter because your trans will be dead in 2 weeks. you can't spin a stock 4L60E past 6300 rpm's without it grenading very quickly. you may as well get torque management deleted because by this time next month, you'll be shelling out more money for a built trans if you don't leave your shift points stock.

probably not the answer you're looking for, but i'm just being honest. rpm's are the biggest killer of 4L60E's.

Based on what? My stock trans had 60K miles and over 130 track runs with most of them over 6300 rpms, no torque management and a high stall converter before it was retired without a problem. While there is no guarantee with the 4L60E, a trans cooler will go a long way helping these trannies live longer.

I have stall shift kit stock cam right now and I don't shift until 6200 to 6400. I haven't had any problem yet. I just want to know if I will if I cut it off..

I got rid of my torque management when I had it tuned, I have had no problems at all with my car.

Delete it!!!

did you have an MS4? rpm's are the #1 killer of 4L60E's. it's been shown time and time again. the 4L60E can't provide enough lubrication to certain parts over 6,000 rpms (the MAX rated rpm for these transmissions). this causes things to overheat and crack, and a lack of lubrication causes all sorts of nasty grinding. this is fact - rpms + 4L60E = death. it's not certain when, but i'll give his tranny 2 weeks before it blows up.

ChocoTaco369

you may be okay with shift points of 6200 rpm's or so. however, the MS4 would probably like a 6800 to 7000 rpm shift point in order to maximize its gains. if you do that, i guarantee your trans will be dead really soon. you may be able to stretch its lifespan by keeping the shift points low, but it's still only a matter of time

4L60E's are good trannies. you just have to be reasonable about them. increasing power 100rwhp over stock and increasing shift points 800+rpm's over the maximum rated level and expecting the trans to hold is ridiculous IMO.

I just turned mine off two weeks ago. I don't have a high Horsepower car though. I do have a 3600 stall converter. I launch only at about 2-2500rpm and shift at 6000. I have not had a problem so far. I had it on all of last year and the first 3 weeks this year. We will see how it goes i guess.

6800-7000 i think building the motor would be in order, then if that were the case a stock 4l60 wouldnt hold the power then you add the stall tq mngmt and rpms. To answer your question you can delete it dont worry about it. But taking the motor or trans past 6400 you will have to do building on both

ChocoTaco369

a lot of people turn their motor to 6800 rpms with just upgraded valvesprings and pushrods. bearings wouldn't hurt, either.

What does a MS4 have to do with it? LOL Believe it or not most aftermarket cams need to be shifted above 6300 rpms. I was shifting my LS6 cam at 6600 rpms and my 232/232 cam at 6800 rpms. My TB SS shifts at 6500 rpms (6400 rpms stock) at WOT with TM reduced and it hasn't blown up yet (been longer than 2 weeks since I tuned it).

If its a stock trans I VOTE LEAVE IT ALONE If its well built then its definatley advantagouso turn it off.

delete it and just remember the limits of your trans. IE: BE SMART ABOUT IT

No tq management here!...3600 stall, stock tranny w/66k miles, 6400rpm shifts and I go WOT every time I drive it. Been fine for 2 yrs so far.

says who? I was shifting at 6400 rpms for almost 2 years in a stock 4l60e with the f-13 cam with no problems. Some guys just have better luck than others but don't just state that it will fail. Just like the 10-bolt some break stock and some it'll last some mods. Yes they're both weak links though, don't get me wrong.

and I had deleted torque management compeltely

From what I've read here everyone has been stating that they have this cam and that cam and shift at anywhere between 6300-6800. What ChocoTaco is saying is specifically for the MS4 and cams bigger than anything that has been mentioned so far. We're talking about 239/242dur. .649in. 609ex. on a 111 or 112lsa. This cam is best at 6700-7000 rpm. The F13(230/232, 594/585) 114lsa, a 232/232 cam, LS6 (204/218 .551/.541 117.5 LSA), ASA (226/236 .525/.525) 110 LSA, or anyone else that has mentioned anything hasn't even come close as far as how big there cam is and the rpm shifted combined. When you start talking about cams of this size they make peak power at a MUCH higher rpm and don't do anything for the most part on the low end so your constantly revving it to make it move. Add a converter to help and a set of 3:73 gears and your helping things a bit but your still giving the 4L60 hell to make the car move at low rpms. With a cam that large he will be making peak power about 6700+. The reason I said anything was I was going to go with a Vindicator cam...it has about the same duration as the T-Rex, MS4, etc. My friend explained that my tranny would last about a month and I'd just ruin my new stocker. He said go smaller...around 230-232 dur. with less lift of .600 or less and I'd be in better shape as the power band comes in at lower rpm and peaks earlier at around 6300-6400 (which most of yours seem to do) as opposed to 6800-7000 range. The extra 400-600rpm make a big difference on tranny longevity.
For the record with my baby TR220 cam I have no torque management and my friends car doesn't either. Both do just fine even with mine having a Yank SS3600 with a tranny cooler.

These are some good points!! I'll probally shift it around 6700 0r 6800rpm when I'm racing for money, I will shift below 6500 just playing around or at the track getting times. I quess really what I want to know now is, If I shift at say 6800 with tq management off or If I leave torque mangement alone or drop it to 50 75%. Will there be that big of a difference in strain on the tranny? Either way I'm shifting at high rpms. I don't know I quess I might drop it to maybe 50% and put back some money to get a new one lol.. Really the only time i feel tq management kick in is when I'm babying to car on the 2nd gear shift. If I'm wot shifting the car my self I don't notice it much...... but if I go wot and let the car shift it self thats really when I feel it. Kinda weird... thanks guy keep sugestions coming

you got any track times with the 220 cam and 3600 stall?
