2003 Chevy Trailblazer 6 cyl Two Wheel Drive Automatic 95,000 miles
P0128 seems to be about the thermostat.
P0753 is my main concern symptoms does not seem to shift into last gear I am doing 70mph at 3500 rpm's
from research I see its silenoid A. I plan on taking it to have transmission serviced can I request they replace this or will it require a rebuild?
Or is this something I can replace on my own I am mechanical by nature but when it comes to transmission I dont want to mess it up.
