2006 Nissan Titan Crew Cab XE 4dr Crew Cab 4WD SB (5.6L 8cyl 5A)
Bad Tranny
 We just bought this titan crew cab and it has less then 5000 miles on it and it slams into reverse. whats with that. but driving the tranny doesn't struggle at all. all its power is easily put to the tires. never had a bad shift when driving. just putting it into reverse. other than that it's a great vehicle.
