Can any 4L80e go with a 6.0?

Can any 4L80e go with a 6.0? I am putting together a drivetrain for a swap and already have a complete 6.0 but am still debating on weather to get a 4l60E or 4L80E. From what I understand I can use any 700r4 or 4L60E (using a manual programmed PCM for the 700R4, a standalone for the 4L60E) or a 4L80E. What I am asking is what year 4L80E can I use that will be alble to be programmed with my 2002 Denali motor and PCM?

You didn't say whether this is going to be a 4x4 or 4x2 application. I assume it is four a rear wheel drive only. A 2001+ would work and have some updated parts in it. I just picked one up for my f-body a month ago. TCI makes the stand alone units for both the 4L60e and 4L80e transmissions. Both will bolt right up to the motor with no issues. The 4L80e is quite a bit larger than the 60 if that is a factor for you.

Sorry, it's going in a 4x4, any difference in years?

I am not familar with the tranfer cases available with these trucks. I would ask the dealer what transfer case comes with the yukon with the 4L80e. The 2001+ have some better parts in them from gm to strengthen them up. There are transfer cases that have both driver and passenger side shafts so you need to look for one that will work with what you already have.

What year is your 6.0 ? The earlier years 99 and 2000 had the iron heads and a longer crank. They switched to just a crank spacer and aluminum heads in 2001 so if you do want to use a 6.0 you will need this spacer.

I have a powertrain about ready to go into my 95 Chevy Z71 that is similar to what you're building. I've got an LQ9 6.0L engine, 4L80e transmission, and NP241 transfer case. First, the electronics. I'm using the PCM from a 2002 chevy 3/4 ton truck with the LQ4 engine and 4L80e transmission. You must get a PCM that has the operating system on it for a 4L80e. If I were you I'd definitely purchase a tuning software package for your PCM. HPtuners seems to be good, and I use EFI Live FlashScan. I really like EFI live, it has native USB support, and the cable can do datalogging without the computer in the car with you. With a tuning package you will be able to load up the engine tables (fuel, spark, rev limiter, etc) for a Denali LQ4 (325 HP) onto your PCM. Then you can adjust the transmission shift times, speeds, etc. to fit your application. The factory PCM is much more capable (in many ways) in terms of transmission diagnostics, programming, etc than the aftermarket controllers are. Plus the transmission and engine work better as a system with the factory computer controlling them.
As far as mechanical stuff goes, get a 2001+ 4L80e. There were many changes made, and 2001 is the latest version. Get an ATSG manual for a complete listing of the changes made. The NP241 transfer case is the chevy floor shift model for the 1/2 ton (and 3/4?) trucks. It is a very stout unit, according to New venture's website it is rated for 5500 ft/lbs torque (I assume this number is the output torque in 4L0). Yes, 5500. Most of these transfer cases are found behind 4L60es, which have a 27 spline output shaft. The 4L80e has a 33 spline output shaft, so you will need to replace the input shaft in the transfer case if your donor case came from a 1/2 ton truck. This is not very hard to do, but it requires tearing down the case. Get a good set of snap ring pliers before you try this, that's about the only special tool you need though. This teardown will take an afternoon or so.
My 6L motor came from a 3/4 ton truck with a 4L80e, so it had the flexplate with crank spacer already. That's all you really need to get the two to work together.

Jesus, that's exactly the info I needed. One more thing though, do you have a part number for the 4L80E to 241 T case adapter? I am using a 241 also but mine has the drop on the other side (241C). Thanks!!!! That's great info, I'd buy you a beer right now if I could.

The 4l80e came behind a 6.0...
2wd and 4wd..
the computers are the same just need to be flashed to what trans your using etc.
the 4l80 is a heavy duty trans for torque compared to the 4l60e, but if your just going to drive it around the 4l60e will hold up just fine. the transfercases are made for both drivers side and passenger side so determine what you need before picking one up..my best recomendation is to find a 1500 or 2500HD Chevy truck with trans transfercase computer and use it all to fit your application.
need any more info just hollar..
thanks jaybo

I already have a T case, a 241C that will work for my straight axle front AND most importantly has a speed sensor. Also have a PCM that came with my complete 6.0. Only issue with my 6.0 still is that it has an electronic throttle, so I'm going to swap it out.

yes that's what I'm looking for. It looks kind of short though. The one that I'm using for my 700R4/4L60E type transmission is really tall and raises the T case up pretty far. I'm going to have a really funky crossmember.

If so, that's 15724745. 6 bolt to 6 bolt trans to transfer case adapter.
