Your post indicates you want to swap the manual 4 speed for the manual five speed. Then why put in the junk line about an automatic/torque converter. Anyway. do you have/own the 190E with the five speed. If you own it and haven't lost or sold the parts just switch it over. It should swap over with really no problem except the drive line length might have to be modified. Sometimes the transmission cross member or rear transmission mount has to be changed. So just get at it, it something doesn't fit, let us know. I would recommend that you keep the factory clutch with each transmission.
