Yeah, something like that. You have to consider that torque and horsepower are RPM dependent, with max horsepower toward the engine's redline. Running the engine slower in fifth means it can produce less horsepower at that slower RPM. So, depending upon exactly what the gear ratios are, it's not suprising that there are cases where the car cannot go as fast in fifth as it can in fourth. Craig

In 5th gear the engine may be too far behind the torque peak to overcome the aerodynamic resistance at high speeds. The 5.0 mustangs were that way as well. I recall reading a Honda Civic road test in one of the car mags years ago, wherein it reached top speed in third gear. Fifth and fourth were considerably slower. Someone please correct me (I left engineering and went into econ for a reason), but I believe that aerodynamic drag increases with the square of velocity, while the power needed to overcome that drag increases with the cube of velocity. So with a too-tall fifth gear, the drag overwhelms the engine's ability to put the power to the ground sooner that it might in a lower gear. Or something like that. Now off to finish reassebmling my transmission (which I wish was a 5-gang), Tom

The 5.0 mustangs were that way as well. But not so my 5.0 Camaro. It's got a tall fifth gear that will get it to 143, past redline in fourth. But it will not get to redline in fifth, of course. I raced my brother's 5.0 same-year Mustang, and whupped him. Twice. -- Jim

Interesting thing is that top speeds rating in the owners manual states that a 5 speed W123 will go faster in 4th than 5th for example a 230E fitted with 5 speed will according to the operators manual do 112 mph in 4th and 105 mph in 5th. That's true for MOST Mercedes models. 5th gear is an economy gear - 4th (usually 1:1) is optimized to the power peak of the engine.

Re: [MBZ] WAKE UP FOLKS, Euro 85 300D manny tranny
I am not sure but I think it is overdrive. Why else put a 5 speed in there? My old 81 200 from south Africa has a 4 speed.
