1slow06SSS Posted September 29, 2014 Report Share Posted September 29, 2014 Im getting to the point where im gonna have my trans refreshed and either sell my truck or buy a complete l92/6l80e drop out with harness etc and swap. Has anyone performed the swap? Quote Link to comment Share on other sites More sharing options...
silveradoss_3 Posted September 29, 2014 Report Share Posted September 29, 2014 I did the l92 swap in my reg cab. But didnt go with the 6l80. Sure would be nice to have the 6 speed Quote Link to comment Share on other sites More sharing options...

chpspecial Posted October 4, 2014 Report Share Posted October 4, 2014 The only gen 4 ecm that supports serial data is the e67, that with the t42 and you MIGHT be able to retain the gauge cluster functions as long as the bcm can be programmed as if it was a trailblazer ss. And that's a big MAYBE. if you go e38ecm you will have to piggy back an ls1 pcm in order to maintain your gauge cluster.
