The Diesel 5-speed has the same gear ratios as the gas 5-speed (like my WBX 5-speed AAP), but the final drive is different. I can't tell you what my RPM's are at any given speed because I still have yet to get my tach working since I switched from Digifant 2 to Motronic. I think that a five speed is good because it delivers more torque. You probably get a good top end rpm also, though I would like to know the numbers. I can guess mine . When I had a 4-speed air-cooled trans 60 mph was right around 3200. So with the gas five speed that might be closer to 3000 in the five-speed. The 4-speed Diesel trans seems like the first 3 gears are all first gear. I definetly recommend a trans swap from Diesel to air-cooled trans if you are using a 4-speed. You will get better fuel economy. Robert 1982 Westfalia --- Don Hanson <dhanson@GORGE.NET> wrote: > I have one in my 84. With a diesel 5 speed > trans.
