W201 Diesel vs Gasser trans & rearend ratios?
I seem to remember seeing a chart that showed the differences in the auto and manual transmission gear ratios available in the W201 cars, depending on whether the car was a gasser or a diesel. The same chart may have included the various rearend ratios supplied with the cars, again depending on whether they were manual or auto, diesel or gasser.
I have searched and not been able to find this info - can anyone help? Of particular interest would be the tranny and rearend ratios for an '84 190D 2.2 with both possible configurations (automatic or 5-speed). Steve.

http://www.peachparts.com/shopforum/showpost.php?p=644599&postcount=3 I believe the rear end ratio was the same for the 190D-2.2 in either auto or 5-speed form. I have a spreadsheet at home somewhere with the transmission gear ratios in it as well. If you need it let me know and I will try to find it.

Great link.
Thanks for the link, Cornblatt. That's quite helpful. I see that the 2.2 diesel is not included in the chart.
It's my understanding that the diesel specific 5-speeds have a lower first gear than the gassers, but I can't find the numbers now. If you can find that spreadsheet easily, I would really appreciate the information. I'm about to take delivery of a 190D 2.5Turbo car with a bad transmission. I'm trying to figure out what I want to do with it - replace/repair the automatic, or do another 5-speed swap. I did a 5-speed swap into another 190D 2.5T, using a gasser 5-speed and the stock 2.65 rearend. This made for a very "long legged" car, but it was very sluggish from a dead stop. Thanks again for the info. Steve.

I can give you the '87 US ratios, hope it helps:
190E 2.3: 3.27:1 190E 2.6: 3.27:1 190D 2.5: 3.42:1 (manual) 190D 2.5: 3.07:1 (auto) 190D 2.5 TURBO: 2.65:1

I copied down all of this info a few years ago from a Polish website that no longer exists, so I can't confirm its accuracy. I did save copies of all of the web pages though, so if you need more info, I might be able to find it in the pages I saved. Let me know if you need anything else!

Awesome.
That is excellent information. Thank you very much Cornblatt. You are "The Man". I'm glad that someone in Poland took the time to compile that information.
Now I have a much better idea of what my options are for both cars. One last question - do you have any idea about whether it's possible to retrofit a 5-speed 2.2 L car with an auto trans. My main concern is the vacuum control going to the transmission. I'm not sure if the 5-speed IP's are capable of being converted for use with an automatic. SteveM.

Even though my auto tranny operates as designed, the lack of an overdrive spins the motor too high at highway speeds. I would swap this car to a manual also if I can find a donor within my pirce range. Can't imagine anyone wanting to go in the opposite direction?

As for my gearing- I went with the drivetrain a 1992 190e 2.6 Sportline. 5 Speed ratios were: 3.86 2.18 1.38 1.00 0.80, axle ratio was 3.27 which equates to a 2.616 final drive This setup is virtually identical to the euro version which has gearing of: 3.86 2.18 1.38 1.00 0.75, with an axle ratio of 3.46, which equates to 2.595 final drive. The difference is that my gearing in 1st through 4th gears are a little taller than the euro version which probably gives me better mileage because my revs will be lower, but at the expense of a little acceleration capability. This is fine with me as I am looking for better mileage overall anyway- the car is plenty fast as it is. All in all this has been a completely fantastic change for me with no regrets...a shame these cars didn't come here with the 5 speed arrangement to begin with. About the only negative has been the fact that it is tougher for me to juggle driving while manually shifting and holding a cup of my favored Dunkin Donuts Java! J.G. |

Jay - Do you have any vibrations when in 3rd or 4th gears and the PRM's drop below 1800/2000? It seams like the 2.5 would have plenty of torque at those levels?

I bet you could go for a taller diff and reduce fuel consumption even further without any loss in acceleration. 2.65 in mine is perfect.

Since you already have a 190e 2.6 diff and axles, a 300e 3.07 would drop right in. Only other change required is the speedometer of course which can be swapped between the W124 and W201 clusters.

Hmmm...hadn't considered the W124 3.07. I thought they had different a mounting setup and bolts wouldn't align properly in the rear subframe??....Also- will the W124 speedo actually fit in the W201 cluster? I thought they were different as well...
