Manual Trans Gear Ratios
 

Some of the guys on my other forum <BangShift.com> are wondering what the ratios are in my '84 240D manual 4 speed. Pretty sure neutral is 0.00:1 and 4th. is almost certainly 1.00:1, but what about the others? They're not too concerned about reverse!

Hope someone has this -

Nitske says 3.90, 2.30, 1.41 and 1.00 forward with a 3.69 diff on the W115 and W123 240Ds. Is neutral a ratio?

Sixto
87 300D

W123-240D-Getriebe/en

I: 3.90; II: 2.30; III: 1.41; IV: 1.0; R: 3.66

The ratio is input : output so technically, neutral is 1:0. Now explain to your wife why she shouldn't park in infinity.

I have the 1981 Mercedes data booklet for all passenger cars -- that lists three different variations of the 716, all with slightly different ratios, so I'll put those up shortly. I believe 1st ranges between 3.90:1 and 3.96:1.

716.005 and 716.006 up to April 1977: 3.90, 2.30, 1.41, 1. Rev 3.66.

716.006 starting May 1977 ("superhigh teeth"), and 716.007: 3.98, 2.29, 1.45, 1. Rev 3.74.

716.1: 3.96, 2.34, 1.44, 1. Rev 3.72.

Thanks for the data! Sounds like there are some slight differences based on application but they're all in the same ballpark.

One of the guys on BS is thinking about a OM617 in an '83 T-Bird. Interesting swap! He was surprised that I found my manual trans from a 240D. Lots to learn in the Benz world!
