Modity 124 trans to start in 1st gear

[brewtoo]

Just got a new book, E-Class Owner's Bible from Bentley Publishers. This is Stu Ritter's book.

It says,"...valve bodies from 1989 through 1991 can be modified to have a first gear start every time..."

We have a '90 and a '91, both bought used. The '91 always starts in first gear. I had assumed it was that way from the factory but evidently not.

I'd like to know how to modify the valve body on our '90 so it will also start in first gear instead of second.

Anyone know how this is done?

Thanks
