i know not another 4l80e thread, but i was wondering where are you guys that have them finding the used trannys. i know the JS kit, controller, and 3000stall convertor are a must, but what type of rebuilds are offered.

Re: 4l80e

I have found them 3 different ways.

1 through a friend that knows someone with junkyard. In fact he has 2 cores right now my buddy is picking up.

1 through ebay (going in my truck).

1 through tranny guy who keeps cores in stock. Had him build Daron's tranny and he supplied the core.

I have noticed they are going down slightly in price, which is good.

The best years to get are 1996 and newer. Although if you do find older one, they are so beefy I doubt for all but the ultimate buildup it will hold fine.

You can back date the early ones with the "update kit" from GM. Dunno the price for it (yet) and I agree that any syty would be hard pressed to hurt a fresh 80E no matter what the year.

BTW, Jeff what are rebuilt 80Es going for in your neck of the woods? The locals here in podunk VA are paying $2k+ for stock rebuilds and $3k for hipo builds without batting an eye.

Re: 4l80e

Daron's tranny was $1700 + $450 core. Red clutches, typical mods. 12k mile 12 month warranty and the guy that built it knows what truck has, and is in. Good guy.

Jeremy's tranny was a basic rebuilt, stock BW clutches, HD2 shift kit. Nothing special. Really the budget model. Either the tranny is rock solid, George sprinkled in that special Blake dust he didn't tell me about, or both. Tranny is rock solid.

It is SO nice to go to track and not even think twice about a tranny issue. In 6 hours we had 10 passes in at track #1. Then drove 30 minutes to track #2, got in staging lines, raced drove directly back into staging lanes again and raced again. Never fearing any tranny heat or failures. Did I mention the shift points are dead on consistant also and we drove 2 hours to track, and 2 hours home. Fluid is still so clean it is hard to see on dipstick.

Re: 4l80e

I just pestered Jeff about this topic. May be useful to know that the "general" ballpark price for the swap would be about 5K. That would include tranny, JS kit, converter, and controller. I may have forgot something, but it was useful info. Thought i'd pass it on.

Thats not really too awfully bad if you take into consideration what a couple blown up 700s will cost you in the long run and even if you stick with a 700 its not a matter "if" the trans will scatter again its "when". Some careful shopping will bring the cost down slightly as well. I missed a new in the box TCI/FAST trans control that went for $100 on ebay a couple weeks ago (dammit!) so if one is smart as well as in the right place at the right time the price can be lowered some.

Re: 4l80e

Even if you are resourceful enough to do the adaptor parts yourself, it is a more expensive tranny to get converted. No doubt.

Where it pays is no worry anymore. And in the slight chance you did break something be a cheap fix after conversion is done.

Granted 4l80e isn't for everybody.

Re: 4l80e

Giving a price is tough because I do so many different options for guys. I'm small enough I can take the time to set up how you need it. I get my cores from a local junk yard. They save all the 4L80E's for me. I pay $550 for cores. Jeff, if you know a better source let me know. I'll take all they can give me. I'll drive down and pic them up.
I can do all billet internals, stock internals, stock with cryo, etc. The price varies. Now if you tell me your running 30 psi boost, running nitrous, launching with 20 psi and doing bracket racing every weekend and doing test and tunes twice a week, your getting billet or you can go somewhere else. All my output shafts are cryo'd. It's just piece of mind.

I reman them so every sensor, steel, clutch, sprag, gets replaced. Some builders keep price down by doing an air check then just replacing clutches. And that's fine. I just don't choose to do that. That may be why mine are a little higher. They are also dyno'd. That adds a little. I recommend getting the converter from whoever get the trans from and have them dyno the trans and converter together. That way you don't get everything in and find out you have a bad converter.

You get what you pay for. Regardless of who you go to or how they do it, your gonna have a REALLY hard time breaking one. I think the rear end is the next weak link.

The thing that I try to get through to guys is that an all out 700 is more expensive to build than an all out 4L80E. That no crap. The problem is that you have to do the controller, both driveshafts, and the converter, and Jeff's kit. Most guys like to "piecemeal" it a little at a time so they don't see how much they paid. The 4L80E forces you to do ALL of it at once.

I did the minimum to Jeremy's that I felt comfortable doing seeing how it was gonna be used. And I will do this for anyone else that needs one if their setup is along the same lines. If you can find a core, you can ship it to me fairly inexpensively to have done as long as your in the continental US. I have an account with R&L. I recently sent a 4L80E kit to New Jersey and it was only $124.

Feeling comfortable about my 4l80e build is that why you couldn't make it to the track last sat? So you would not feel any less "comfortable" about it.:rotf: :rotf: Just joking!!!!

George is one of the best. Highly, Highly recommend him to any one, 80e or whatever. Transmission has shown no signs of anything!! Fluid usually looks so good, I feel really stupid about changing it!!!!!

I'm sorry Jeremy. Wife was PMSing and she was sick. Dillon and I were both forced to be miserable all day. :rant: :tdown:

Pickups, SUV's, and Vans in 3/4 ton & 1 ton varieties.

Depending upon year and application, the 4L80E can be found behind engines ranging from the 4.3L V6 (not a turbo) to the 8.1L Big Block. I believe the option code for the 4L80E is MT1, don't remember the option code for the 4L85E (slightly upgraded unit). Most popular location is 2500 pickups with the 6.0L V8. Late model pickups with the 8.1 or diesel use the Allison, so be careful when searching through CarPart.com......

Pickups are the most common applications. Don't overlook the vans, however. There are often real good deals on them because there isn't all that much demand (vs pickup & SUV parts).

Shipping is one of those things that can be really tricky. I just shipped a complete 6.0L LQ4 motor and 4L80E from a 4wd 2004 Silverado 2500, from Rhode Island to Baltimore. Cost me $130, engine on skid weighed 635, trans weighed 298 (complete with TC). But I had quotes ranging from there to $385, depending upon vendor and whether they got the freight class correct.

Re: 4l80e

I was thinking about the trans controller when I was reading LS1tech trans forum this morning. For the swap they only have to use an adapater harness to go from 4L60E to 4L80E. Wouldn't those of us that are swapping to an LS1 just need this as well? I'm pretty sure the ECM is able to control the trans since the LS1 is paired with a 4L60E as an option.

This make sense?
