The 5 speed is great, except on the higway. It pushes 3000rpm at 65mph..that is just awful. 6th gear would be great, but I am sure they regeared every gear so it has more gears in the lower range and is still awful up top. For reference, a v8 LS1 car (like a corvette) makes about 1200 RPM at 65 in 6th. Even my v6 firebird does much less than 3000 on the highway. Lower revs means better milage. I bet this thing could make 28 or so highway instead of 23 if it weren't for that stupid 5th gear.
At 65mph, in 6th gear, the diesel is sitting on 2,000rpm (right in the middle of it's max' torque band) and is very quiet. Have just purchased a modified clutch valve from Zeckhausen in the States, and am looking forward to puting it in.
