First gear of the 6l80e is useless anyway with a decent amount of power, just do an 80e and make enough power to help the slow first gear.

 

I guess I'll have to get one and find out

I think all the comments/threads of 4L60s exploding make me paranoid lol

 

Well, I'll just install the blower with my current cam and be done with it so no big power numbers, I just want a bit more fun on the streets and don't plan to push the 5.3 over 8-9 psi.

Besides I drive a lot on heavy traffic, lots of stop & go, so I don't think I'd like the 4L80. Who knows, I may end getting one if everything else fails.

 

start s slush fund for either a 60e rebuild or a 80e swap. One day your going to need it.

 

No first gear is AWESOME. I never understand why everyone wants short gears in the rear 4.10, 4.56, etc. but then when the gearing is given to you in the first gear of a transmission..."oh it's useless!!" Gear multiplication is gear multiplication! The truck needs as much torque to get 4500+ lbs moving from a standstill with a 1800 RPM stall. NOW if you have a 3200+ RPM stall speed converter, well THAT's a different issue.

I can't wait to be able to do a 4WD burnout in my 6L90 TBSS.

 

has anyone found anymore information on this swap?
Does anyone know if it has been done yet?

I have a 2006 crew cab silverado, just got a 5.3 and 6l80e from a 2011 truck with 2k miles on it. i have been looking at wiring and pinouts for the past few days and it doesnt seem impossible. I would like to be the first one to do it, but im sure someone has done it already.

 

I'm pretty sure a full drivetrain swap can be done, but the wiring will be intense.

You will probably have to keep the stock pcm to run many functions in the truck, but somehow piggyback the new stuff (everything from the donor vehicle: PCM, TCM, engine/trans, harness, etc) so that the new drivetrain can run itself but still communicate with the truck itself (gauges, fuel and ignition, climate/ABS/traction/cruise control systems, etc).

The 2011s have all the latest technology... flex fuel, VVT, 6-speed auto, etc etc so its just that many more things to work with that the existing truck didn't have.

As i understand, almost all of the programs (tunes) for our trucks comes by way of a windows-like user interface where the tuner can only modify functions in a limited way. The only way I see to integrate two different generations of electronics is to have an actual programmer (computer science grad/software engineer) go through the source code (guessing it's Linux based or the like) and modify each area of code as needed. Costly and time consuming depending on who does the work.

Many of the electronics (sensors, gauges, etc) will probably have different resistances and current ranges so that'll be a factor. If they'll fit, it might just be as simple as acquiring all that stuff from the donor vehicle and making them work in your current truck.

It'll be a "fun" project if you have the patience and money, but most people will just buy/trade up to the new generation truck.

 

You don't make enough power. Any of the guys making decent power(600+) spin bad out of the hole in 4hi why would they want more gear. Thus my suggestion, do the easier 80e swap and add more power. Both are cheaper and easier than doing the new stuff swap. I know your opinion is biased since you sell the conversion parts but there's no way I'd spend the 4k you want for that swap.

 

I don't see why an older truck couldn't be fitted with a newer PCM and wiring harness and make it all work that way. Just delete all the VVT and Flex fuel parts of the tune and it should run any old 5.3.... The only thing would be going from a 58x to a 24x reflector and the different cam sensor signal. It's been done from old to new, just need to figure it out the other way.
