6L80e question?

[ocracokenc]

I have been trying to find info on a question I have about the 6L80e in my 2014 Silverado with the 4.3 but can not seem to find the info. I have been wondering since they use the same transmission for the 4.3, 5.3 and 6.2 EcoTec do they do anything different for each model. What I am getting at is if the transmission in my truck is the same thing one with a 6.2 has then it should be less stressed dealing with only 285hp and 305tq or do they upgrade various parts for the bigger engines? Thanks for the help.

I know on the 4L60 different engines sometimes got different torque converters but I believe the rest is the same across all trucks aside from the cases being different for 2 vs 4WD

I do know the part numbers are different, but I don't know why actually differences there are.

There are 4 different torque converters. I think just about everything else is the same. Oh, and obviously 2wd vs 4wd, the transfer case adapter vs. the normal tail end.

Probably just a torque converter and different programming

yeah i know the TQ convertors are diff but i would also think they way they are programmed ?
