I have a 04 4WD / V8 Sport with a 5 speed that I have been driving in 4th gear, rather than DRIVE! I just read the manual last night and realized that I’m an idiot for not reading it before. I have babied this thing for the last 2000 miles, constantly adjusting my speed from an average of 50 MPH – to 65 MHP, 90% highway. HOWEVER, I’VE BEEN DRIVING IN GEAR 4, opposed to DRIVE! I doubt this has helped, but has it HURT the Transmission???? What’s nice is that I was seeing an AVG of 17.5 MPH in 4th, and now that I have learned to read, I show an average of 22.5 MPH. I just changed to Mobil 1 synthetic which might contribute to the increase of gas mileage as well. Damage done??Comments much appreciated!
