My 2005 Chevy Trailblazer 2WD won’t accelerate beyond 25-30 mph, transmission fluid was replaced/flushed. I’m taking it to a shop today, any suggestions? thanks
It can be tough when trying to diagnose your Chevy Trailblazer for lack of acceleration. When it won’t accelerate normally there are a few things that might cause this. If the check engine light is on the first step would be to pull the engine trouble codes. If the engine seems to rev high and your Trailblazer doesn’t want to move at the same time, the most likely reason would be low on transmission fluid. Check the fluid level first. If the level is low, top it off and resume testing. If the transmission fluid level is full, take note to the color. If it is burnt looking or dark, this would indicate burnt internal clutches. Rebuild the transmission to fix it. If the color still looks new, and internal valve body or solenoid issue is most likely the cause.
