I was wondering if the torque managment function being shut of via HPTuners could possibly be the cause of my two transmission failures. It's only the third gear I seem to have problems with. The torque management serves as a reduction between shifts to prevent damage. While the car maybe faster with it turned off, under hard acceleration, I think the the torque in combination with the 2nd gear ratio is actually too much shock for the third gear to handle when it's transferred during the 2-3 shift causing the gear to break. I do not grind the gears while shifting, so that is not an issue and my shift linkage is new and perfectly adjusted.

Does anyone else think this could be my problem? My logic behind this is I never had an issue when it was turned on, but when I reflashed the car with a new tune removing it, that's when the 3rd gear issue started happening. Your thoughts and comments would be greatly appreciated as I would like to prevent this from happening again as transmissions are quite expensive. I also think that it's time to get mounts as the torque dampner alone probably isn't cutting the case. Thanks.

 

you know mounts will apply more stress?

I would think the torque reduction would probably be a good part of the reason.
i mean, its there for specifically that reason right?

 

probably, but I've had my tq management shut off forever now, I just granny shift the car... still pulled off a 13.3 though

 

My torque management has been off for a while thanks to ^^^^ that guy! lol, what's up Paul?
Everything has been fine. Just a bit of info for you.

 

I was unaware that tq management was activiated in 3rd gear. Mine is setup in first and second, but not third...

 

torque management is not active in third gear.

it comes down to driver error.

 

You say torque management is not active in 3rd gear, but I just looked at the GM Stage 2 tune I have, and it has a significant reduction % in these following areas as torque increases:
1>2 shift
2>3 shift
3>4 shift

Look under Trans/Torque Management/Performance to see what I'm talking about. I bet this could be an issue. As for my driving, I know I'm not the best but I'm not that bad of a driver. If you do some research the SRT-4 guys have run into the same issues as well with 3rd gear. Luckily the place that builds their trannies is willing to do ours too. I just have to scrouge up some funds so I can have them work their magic.

 

all of mine under that heading is blank. i have nothing in terms of torque management control in that section.

then again, i have an 07

 

Hmmm.... That's intersting. My custom tune has it eliminated, and the GM Stage 2 tune has it all adjusted according to the torque amount vs. % reduction. Well, all I know is that mine is going back to those settings to help alleviate any strain. I'll keep everyone posted.

 

please keep in mind, that every single year of these vehicles is different. well in terms of hpt goes.

05 got the cool stuff
07 got screwed
06 is somewhere between the two

 

Ain't that the truth!

 

what do you mean 05 got the cool stuff. don't all years have the same options?

 

as for the tranny functions, thats for an automatic trans, not the manual, and 07's pcm doesn't seem to have the support for an auto like 05 and 06

 

Are you positive? I believe it is a function for ours because if it wasn't it would be grayed out like the other functions no useable to us. I'm curious now.

 

It could be a contributing factor. We have a lot of local cars around here with it off and are on the track regularly with no problems but who knows.

Also, anything in HPTuners that applies to our cars in 2nd gear will also apply in every other gear above second.

Edit: Except for the auto tranny parameters mentioned above which obviously wouldn't apply at all.

 

TM delete owns!

 

nope, that they don't. there is little variances here and there

 

But aren't they adding features to the newer models with every update release?

 

i haven't seen a recent release of any info, nor updates

 

Ok .16 HPT software allowed you to modify the LSJ engine, transmission settings. .18 has this removed because ALL settings in the transmission section are null and void for the LSJ since there is no auto transmission out there for us to hook up and be compatible with HPT. So to answer your question on Trans TQ managment, that does not affect us. Now on TQ management on Engine will affect marginally since that table affects the actual throttle position to help reduce airflow which in turn reduces TQ in low RPM/ETC settings. I'm a firm believer. that if you put traction mods on YOU will be adding WAY more stress on the transmission than it was designed to see from a sudden stop. The TQ difference made by changing the TQ management settings are minimum compared to the direct TQ placed on the Axles by engine mounts, braces, thicker tires, Harder clutch engagement. Anyways good luck.

 

So far my tranny as been holding up, and I beat the **** out of it. Soild mounts all around with the Spec clutch. I've snapped 2 axels so far.

Mine hasn't busted but I fear for it. When I coast, the trans makes a loud whine noise, which seems to be getting louder. Starting to do it while giving it throttle too now. I am thinking before I do a Turbo swap, that money might be needed to go into the tranny first.

Let us know what it ends up costing you if you send yours out to the place that does the SRT trans.

 

i have the .18 update. 06 has the managment allowed under the trans, 07 does not.

 

Ditto! I just upgraded the other day and it still has mine available under the tranny options.

I will indeed keep everyone posted when I get the trans built the right way. The guys that are doing the SRT-4 trannies are great, and they are no strangers to GM cars either. *Cough* LS2 Swapped Soltice *Cough* Ring any bells?
