I'm Awesome
Ok not a GMT400 but-
Wife’s 2007 Suburban 2500 with 6.0/4L80 started shifting hard been 1-2 recently, during normal driving. Trans was rebuilt about 45k miles ago, been drama free since then until now. Everything else behaves normally.
I replaced the filter about a year ago. No SES light, no store codes.
I am running a fairly stock tune, pretty much just adjusted for bigger tires(275/70r17s). I reflashed the stock tune, reflashed the current tune, unplugged the battery for an hour, and it’s still behaving the same. I reset the transmission learning in HPTuners. No change.
I don’t even know what to look for or log, but I do have HP tuners.
Thoughts?
