Bit by the manual transmission bug

I loved my '91 560SEL. It was a fabulous car in almost every conceivable way, but I sold it last winter because I just couldn't stand driving a car with an automatic transmission.

I'm currently driving a very nice Volvo V70, but I'm missing all the things from my 560 that make a Mercedes so great.

There are so many beautiful E/S class from around the turn of the millennium that are right in my budget, as gas prices seem to have deflated the price of V8 vehicles (and boosted the value of my 30+mpg Volvo). Nevertheless, I know I won't be happy with a car equipped with an automatic. And I don't want a BMW or an Audi; I want a Mercedes-Benz.

Has anyone here personally attempted a manual swap on the W210, W140, or R129? Is there any reasonable way to get the ECU to accept the missing automatic transmission?

I've got images of an E320 wagon with a 6-speed floating in my head....

The R129 300SL was available with 5spd even in the US.

The only swap I have seen that has a problem is on a BMW, all the japanese and domestic have not mattered. I have a feeling the Mercedes may be similair to the BMW.

I know when you do a 5spd swap on a BMW (E30 in my experience) the car will run good for the first fifteen days or so, but as the automatic computer learns it starts to run worse an worse, disconnect the battery and reset it and it runs good again for another 15 - 20 days... If you install the 5 spd computer it runs perfect.

hope that helps, In my opinion I would still try it, I am going to build a standard E320, but I am going old school with a mechanical diesel... still tons of other electronic issues to address though.
