2006 chevy trailblazer
I will drive my trailblazer it will get up to around 55
mph and the RPM will jump not a lot but you can
fill it then it will stop then it will do it again
Trail Blazers are notorious for the transmission going out constantly in them. I've seen them in the shop at 68000 to 100k Miles several times. But if you're lucky it could be simply the shift solenoids. Good luck
