4l60 or 4l80
Okay, so best friend blew first out of my 4l60 yesterday. Oh well, **** happens, just a car right. Well, now im left in the wake of trying to fix this bad mamma jamma. Heres some info on the truck. It's a 2006 silverado 2wd 5.3l LT2 on a pro comp 6" lift 35s CAI gibson short tubes, F.A.S.T tuner (stuck in economy mode for 91 and tuner got stolen...fml) Just bought 4.11s, havent gotten around to installing them yet, but i will do so probably while this whole trans fixing business is taking place, and just clicked over 80k the day before the trans went kaput. Now, i know myself, and i know the way i drive and although normally i baby my truck, i like the rest of us have my immature moments. Anyway i was halfway done saving up to start on my long/mid travel setup so keep in mind this truck will end up deaverd and coilovered and if not long traveled then at least mid traveled, and i have the intention to actually go play with it (not anything tooooo rough it is still my baby, but you get the idea). anyway.
The goal here is to make it as strong as possible because although i am not rocking a punched out Lq9 with a big s/c or a couple of turbos on it, i will undoubtedly swap to a 6.0 when the engine goes kaput and it wont really be stock for too long. My logic being that if im gunna swap the motor ill have a cam and heads and a few other nifty goodies on the 6.0 before the 5.3 even comes out. so i would like to leave myself a decent amount of grow room
So what would be the best choice? just a stock 4l60, a mildly built 4l60 or a 4l80. What would a mildly build 4l60 run me? cause i can find 4l80s for rather cheap rebuilt.
Another somewhat unrelated question i have is, how difficult would a GEN IV 6.2 and 6l80e swap be if i managed to get an engine and trans with all harnesses and accessories and computers? what else would i need to get it in and working? My logic is if it can work in one truck, it must be able to work in the other somehow. I know the gen 3 computer controls hvac and door locks and all that other nifty stuff, so id probably need to keep its computer to run that stuff, but couldnt you run both computers at once? one to run the actual truck the other to run the engine/trans. Just kinda spitballing on this one but i may have a chance to get a gen iv engine and trans combo lift out for very cheap with less then 10k on them.

The thing i like about my 80, i dont have it to worry about anymore, everytime i ran with my 60e i was thinking ok, is it gonna pop this time. My 80 is bone stock.

80e for sure. I burnt $3k+ on a built 60e and could have gottend a built 80 with a shift for that. You are going to beep burning the 60es. My last truck went through about 4 rebuilds and then a 5th custom build b4 i said fuqit and got rid of it.
Just remember the x member part and yoke and shaft modding that has to be done. If y our down wothout a truck its easy to just throw a grand at a rebuilt but each rebuild adds up.

What exactly is necessary to swap the 80 in?
also, will it adversely affect my fuel economy? i noticed the gear ratios were slightly different?
Like i said, im not gunna beat on the thing, and the most my truck will see will be a LQ4/9 with heads cam long tubes, tune CAI and maybe a bigger intake manifold and throttle body, the goal is to mid/long travel the truck so its not going to be a drag truck or anything like that, i just dont want to break this damn thing again...

also, im assuming i should also do a 14 bolt swap as well, can a full floater be converted to 6 on 5.5? ive already mangled one 10 bolt so im on the prowl for either a 14 bolt or 9 inch for a good price as well.

I just put a 4l80e in my truck with a HD2 kit. It lost around 1-2 mpg and lost a little power off the line but pulls harder from 35 mph on up. Its nice to know the trans is not going to fail with added power and the trans shifts rock solid.
