A little off subject.... if you get auto trans have a trans temp gauge put on with a deep dish, drain plugged pan.
Maybe a diesel one day....maybe....manual gears.....never!
No need for a manual trans, my old 2000 Dodge 2500 4x4 cummins sold to a friend has 280,000 miles on the stock original auto trans. He is a contractor and tows a 10,000 lb dump trailer on a regular basis, the auto trans will hold 6000 HP in a dragster
