i have a 92 dakota with a v6 5spd and am having trouble keeping up the speed while going up a hill. it has a body lift and 33's on it. i lose 5 to 10 mph when going up a hill, not sure what gears i have, someone told me the tires may be to much for the gears? i did a tune up and still the same result don't know what else to do, any help appreciated.

 

thats why you have a 5 speed...downshift, those 33's certainly arent helping you at all.
