My dad made a good point earlier, why not just add an aftermarket/electric overdrive instead of going through so many hoops to get a 5th gear?

This seems like it would be a whole lot easier than having to swap transmission guts or cut/weld different bell housings and making sure everything is aligned properly

Just a thought

Not at all far-fetched. A neighbor of mine has a Dodge Ram, with the 5.9 Cummins, dualies on the rear axle; it has --um, I forget, either a 5- or a 6-speed original transmission. To which he added an after-transmission second gearbox, from a Mack truck. There's a splitter on the stick shift, so he has either 10 or 12 forward gears total. Before he retired, he used to haul fully-loaded full-size car-transport trailers up to and from Alaska with it.

Yeah I think if one could find one for cheap enough this would be much simpler than trying to make what would essentially be a "Franken-transmission", since it seems all you would really need to do would be to modify the drive shaft and come up with some sort of mounting brackets. Now I just need to find a cheap place to find these and do it lol

I was thinking the electric over drive from a Volvo 240 would be fairly strait forward modification it essentially bolts on the rear of the transmission some kind of bracket would need to be fabricated along with a drive shaft in and out of it!

I'll have to start keeping my eyes open when for these volvos when I go to the yards from now on, this seems like the most plausible solution for one of these overdrives
Are the overdrives found on all Volvo 240 cars, or just certain models?

A lot of the 1980's Volvo 240 4spd cars had them look on the shift knob for the switch
If you wire it up correctly you can over drive every gear then you would have 8 spd

So it appears we are searching for 200 series Volvos from 1974-93 with the M46 transmission, this is the one with the electrical overdrive unit installed from the factory. Not totally sure if it was an option all of those years or just some, but at least its a start.

As for the whole 8 gears thing, I'm not sure what I would really need 8 gears for, I guess it might come in handy at some point though lol

Muahahahahaha, I have sourced an overdrive unit for free!!! Turns out the rusted-out-beat-to-hell (from his descriptions) volvo my friend has is equipped with the M46 with the overdrive from the factory, and since he said he will be taking the car to PnP in a month or so I could have it free of charge!!

Everybody I've told about this plan has been like "why put an OD on a manual??", I guess they just don't understand diesel mercedes and the whole super-high-revving thing that they have going on while driving at highway speeds.

Anyway, I will keep everybody posted and try to document everything to the best of my ability for future reference, and create another thread in the "drivetrain" section of the forum for this whole project

(05-03-2012, 03:38 AM)sassparilla_kid Muahahahahaha, I have sourced an overdrive unit for free!!! Turns out the rusted-out-beat-to-hell (from his descriptions) volvo my friend has is equipped with the M46 with the overdrive from the factory, and since he said he will be taking the car to PnP in a month or so I could have it free of charge!!

Everybody I've told about this plan has been like "why put an OD on a manual??", I guess they just don't understand diesel mercedes and the whole super-high-revving thing that they have going on while driving at highway speeds.

Anyway, I will keep everybody posted and try to document everything to the best of my ability for future reference, and create another thread in the "drivetrain" section of the forum for this whole project
Did you ever put this OD in your driveline?

You could also put a transfer case in backwards, so that you would have a 1:1 "low" and a 1:1.96 "high"

Id be interested to see if it fits in the driveshaft tunnel, take a few pics for us. From what ive been reading, those things are like 9 inches across.

I see that as the biggest single problem getting a component like this fitted into a MB body. The tunnels are pretty tight

My original Scimitar gearbox had an overdrive on it. It effectively turned the box into an 8 speed box but using it in anything other than 3rd and 4th would rip it apart. Be careful what you get and make sure it can take the torque or it will be horribly unreliable. Probably easier and cheaper to get a 5 speed or better to be honest but the choice is yours.

ive heard of regearing a transfercase and turning it around. so if you could set yourself up with about a 20%-30% overdrive could be an interesting outcome. are we trying to find a splitter for an automatic. cuz if its a standard you could go with the torque splitter online. i believe they come with a 27% overdrive, and fit between the bellhousing an transmission. just some idears
