Engine Flare Up/Transmission

[viewsatxtrm]

Anyone have issues with shifting between 2nd to 3rd and the truck revs up about 750rpm, or 1000 when towing then catches? Dealer told me it is normal but it has been progressively getting worse over time. Never did it when first bought it but started around 10,000 km doing it weekly where now at 60,000 km does it multiple times daily. Warmer weather does cause this to occur more often and harsh. Brand new transmission as well installed which never made a difference. Doesn't seem right to me as you can really feel when towing the stress on that shift. Wondering to the crazy flare up when under load would cause a bent engine rod recently around this transmission b.s.

Sounds like it is slipping.

Thats what I figured but there engineering department says its normal. I talk to a few others with vehicles which are similar which arent experiencing these problems, and talk to private tranmission shops which feel something is off there. I just figure I am not being lied to cause there was a few weeks the dealer and General Motors wouldnt return my phone calls about what to do next. They still are giving me the run around.

Have a independent shop use their scanner check for transmission codes. If it's slipping you'll have a code. Might not be slipping, could just be athe torque converteer locking and unlocking. Do you use tow/haul mode?

Mine does this occasionally... from what I've read, it's referred to as a "shift flare" or "flare shift."

 

And that's the extent of my knowledge on the topic. ;)

I also have the same problem with the flare shift from 2-3. Many people with the same year body style 2014-2018 have the same problem. A buddy of mind did a flashpaq tune for economy nothing major, and hasn’t had a flare shift since tuning the computer. Might be a cheap fix rather than doing a full engine tune
