Issue / Question:
I missed a transmission service at 90k miles and started experiencing chugging between gears at 1500 rpm at 45 mph. At about 125k miles I got the super duper transmission service and the chugging is still there. Is there a way to tell if I need a new transmission or could it be something else?

What your describing is the transmission is going into 4th gear or torque converter lock up at too low of an RPM causing a chugging sensation! Alright if this is the case I would scan the computer system first to make sure the vehicle speed sensor is fine. If there are no codes I would be inclined to reprogram your computer if necessary, to have it shift later by 5 to 7 mph. I will have to check, there might be an update on this. If not, we can program a different tire size to change the shift pattern; bottom line is if it’s a shift timing problem we should be able to save the transmission. However, if it’s slipping already, it may be too late to save it. A test drive will let us know what to do.
