Q: looking at an old beater to use just for plowing my driveway. it will never be on the road and will only be used to push snow probably never leaving 1st gear. it has a 318 with an auto trans that slips in third gear. seems strong in 1st and 2nd. do these transmissions use the same clutch packs for all the gears is it slipping in 3rd because of the load and will eventually slip in 2nd than 1st or is 3rd a separate clutch from 1st and 2nd thanks .
