the downside of removing TM is that on smaller, weaker trannys, it will wreak havoc on the insides b/c of the added torque you put on it. the 4l60e used in 1500's does ok for removing some of it, and will work if you remove it all, but you have to drive right, no heavy romping on it all the time or you'll fry your tranny. Now if you have a 2500, or a 1500HD with a 4l80e, you can safely remove all of th TM and not have any problems.

In my opinion the only reason GM usus TM is b/c they didnt want o upgrade their crappy tranny's and needed something to cover their butts.

Should my tranny go out, would I be able to put a 4L80e in its place?

allen (nelson tune) will remove 60 percent of the torque management, if you want to remove 100 percent get a shift kit, the stock trans is set up for long, soft shifts, with no torque managment with stock trans it will create alot of heat when shifting, shortining the trans life.

they make conversion parts for the 2wd, they are still working on the 4wd setup due to transfercase

Well, damn. The conversion parts cost almost as much as a tranny.

ya but if you are hard on your truck or plan on putting out some seroius hp you can do the 80 swap or eat 60's

Rookie Question.

How do I know if I have a 4l60E or a 4l80E Transmission. I have the 2004 Silverado Performance Package.

Yes, you can. Allen Nelson has his own forum www.ls1truck.com and many people over there are doing just that. You can also add a shift kit and servo's to make your 60e a stronger unit. As soon as I get my shift kit and servo in place I'm getting 100% TM removed.

Well, I'm sure the dealer could tell you

A good rule of thumb is if you have a 6.0 or greater, then you have a 80e (or an allison, but you'd know that without a doubt). 4.3, 4.8, and 5.3's all use the 60.

With tranny' exact specifacations its hard to say, but this might help... 4.8/5.3/LS1 all use the 4l60e STOCK! LS6/6.0 use the 4l65e Stock, and the 6.0HD/8.1/Duramax use the 4l80e! And the 8.1/ Duramax use the Allison depending on if you requested it.

Yes you can fit the 4l80e in the truck and make it work. Depending on what you're long term goals are, it is hard to say exactly what we should recomend you do to your tranny. If you're looking to have about 600 crank hp which equals out to about 500rwhp, then a FULLY upgraded 4l60e will work. If you plan to break the 500rwhp mark then you can put my word on it that no matter what you do to the 4l60e, it will not hold the power!!! In that case jump straight to the 4l80e. Now I know what you're thinking...(If the 80e is much stronger then why not just go to it anyway?) Well the reason is because its robs a shit load of power from the motor... Where most people see about a 20% loss in power through the 60e. ALmost everyone sees about a 30-35% loss with the 80e. It takes alot of torque to get those monsters turning and its no fun when you dont have enough.

To white lightning: since nobody really answered your question correctly then I'll take a stab at it.
Let see... the question you asked was, "what are the downsides to removing TM BESIDES failure to the trans?" Well other than failure to the tranny there is none, unless you dont include your torque convertor as part of the tranny, but I do. Hope this helps with most the questions

I misread his post sorry. Another downside is buying new tires often, if you're like me

By a "FULLY upgraded 4L60E" do you mean shift kit and servo, or what?

i think he means a fully built, performance clutches and bands, hardened output shaft, sun gear i think, and there are alot of other items, i think a fully built trans is good for about 550 hp

link to performance trans site shows alot of the upgradable parts
