Major transmission problem 6l80
This evening driving home the transmission started to act up. I stopped and shut it down. It started up fine but now I only have first and second gear.... And once it shifts to second it will abruptly downshift to first until I hold it for a minute. Does not have 345or6. Any help is appreciated thanks

It's possible it's an electronic issue. These 6L80's no longer use one way clutches, it's just a clutch to clutch system with the TCM controlling pretty much everything.
Do you still have a warranty?? |
It just hit 20k
|
what year? 4x4 ? engine ? mods? any other info
|
try unplugging you battery for a few minutes...may sound stupid but i only had 1st gear and i stopped at the gas station unplugged the battery and it was back to normal...i was told it went into a safe mode

Sorry to hi-jack, but you made 600/638 with heads/cam? How is the transmission holding up to it? |
