My 2000 Sierra, Sophie

[silverado13]

that would be a good alternative

 

[BigGraySophieTheSierra]

Yessir. And from what I understand they sell em for real cheap

 

[silverado13]

it all depends on cost, find one else where and buying them would be expensive but taking one off a work vehicle is a steal, ive been hearing alot of people complain about their 4l80es though, they are good for power but i wouldnt use one unless your 4l60e wont be able to handle the power, 1st gear on a 4l80e is rediculously long so your gonna get really crappy gas mileage

 

[BigGraySophieTheSierra]

Hmmm, I don't know much about the 80E, but my 60E is doin pretty well. It'll need a rebuild before too long, I suppose I could bullet proof it and stick it behind that 6.0

 

[silverado13]

if my 60e ever goes bad in my 2000, im going to do a 4l65/4l70 conversion

http://www.trutechtrans.com/ this company sells conversion kits

 

[BigGraySophieTheSierra]

I've heard of the conversion, what's the actual benefit to converting?

 

[silverado13]

more strength, think about it, the trailblazer SS has a 4l70e, and from the factory has a 400 hp LS2, and that tranny is designed to handle that 400 hp and have a 100,000 mile warranty from the dealer, so realistically it can probbaly handle 550 hp from the factory, as to where a standard 4l60 is only rated at maybe 350 hp, and people burn out the clutches all the time

 

[BigGraySophieTheSierra]

Ah, okay well hell yeah lol. Them SS Trailblazers are sweet.
Yeah whatever I build whether it's the 6.0 or the 5.3, it'll be more for towing and mud more than anything, think the 70E could handle a bunch of torque?

 

[silverado13]

yeah, i dont ever recommend a 4l80e unless you are making some racecar, or going to be towing ALOT of weight daily, 4l70e would be good

 

[BigGraySophieTheSierra]

Cool, that's what I needed to know haha.
It'll be just a daily driver/toy, but I do like to be able to haul stuff.
I got over race cars after my Firebird Formula lol

 

[silverado13]

people also go with 4l80es because they are a little more popular, i mean they have been puting them in 1 tons since the 90s, as where they only put 4l70es in a few vehicles

 

[BigGraySophieTheSierra]

Yeah, that's a pretty good reason to go with it. Lol I hadn't heard of the 70E but maybe a couple times. And it was never anybody having one, just wanting to convert their 60E to one

 

[silverado13]

off the top of my head, i cant think of anything but a trailblazer ss that came with them, might have came in other things, alot of people talk about doing a 6 speed auto swap, im just not sure how it would be working the electronics on it, i know your stock computer couldnt control it but a 6 speed would ideally be the best but probably the most work, i dont think it takes much to get a 4l70e to work

 

[BigGraySophieTheSierra]

I think it would be a bit of a headache swapping to a 6 speed haha.
From what I've heard I can take my 4L60E and when I rebuild it I can buy a kit to swap it to a 4L70E

 

[silverado13]

yeah from what ive read, thats exactly what you do, the website that i found that sells the kit has everything you need for around $1000

 

[BigGraySophieTheSierra]

That doesn't sound like a bad deal. Probably cheaper than to go buy one already rebuilt

 

[silverado13]

like anything it depends on the deal you find, ive seen them as cheap as $1200, rebuilt but thats by a unknown builder, and all the way up to $2500

 

[BigGraySophieTheSierra]

Yup, I dunno that I'd trust an unknown builder in this situation haha

4l70e also came in later model Silverado SS and VortecMAX trucks. In a light trailblazer 4l70e works great but a heavy truck easy to limp. Plenty of stories out there about N/A Silverado SS destroying the stock trans.

 

[BigGraySophieTheSierra]

Well that's good to know. So the 80E is the safe bet with a 6.0
