I have a 2003 Trailblazer 2wd 6 cylinder with over 200,000 miles on it. I rebuilt the transmission last year because the 3-4 clutch failed. I notice that in 4th gear with the torque converter clutch applied, at 70 mph the motor runs about 1900 rpm.
Now, I just purchased a 2003 envoy with the same motor but it is a 4wd, and only has 100k miles on it. It's in good condition but I wonder about the gearing. At 70 mph in 4th gear with the torque converter clutch applied, the motor runs about 2200 rpm. The trans is not slipping and the fluid is red without a burnt odor. Does anyone know if there is a slight gearing difference that may account for this?
