converting manual to automatic

hey all,

out of interest, how much work would it be to convert a manual to automatic? Whilst I love the car, I feel the auto box would add to the driving pleasure over the manual change.

Whilst I'm sure it's the level mechanism that might need attention, it doesn't glide into the gears as smoothly as i'd like.

Old MB gearboxs, for manuals were always considered to be very clunky. Upgrade your profile so we know what car your talking about. Some people might be intested in swapping cars.

Your best bet really is to sell your manual car, will fetch a better price for been rare, and buy a better condition automatic car

Clunky? They were smooth shifting 4 speed boxes, at least the one in my fathers 65 220SEb. Why do you say they were clunky? What was your experience?

Not part of the in-crowd since 1952. It's BRAKES not breaks. You break a bone, use brakes to stop your car. /rant

@bluefang: unless they are based here, in south africa, and have the same car, restored and happy, there won't be much chance of swapping.

@wbain: It's hard to explain, I think it could be down to the gear lever, it's not the smoothest path between the gears. I'll get my guy to have a look at it in the new year, could be something needs sorting out

my experiance is alot of reading, i have wanted to convert my 450SLC to manual for along time, hence i have read as much as i can about the mercedes 4speed manuals they had at the time on the 350/450 engines and most seem to agree that in general the gearbox was clunky and not very fast shifting when compared with the 5speed getrag manuals that were in comparable cars like the BMWs etc. some of the AMG and purpose built mercs ended up with the 5speed getrag, but very rare.

Well dsan, i am just suggesting that if your car has been restored and is in good condition you sell it and look around for a restored 280SE. Will save you money and alot of hastles with getting the auto into your car etc along with changing over all the parts. With the manual been more expensive due to its general rarity as a Mercedes manual you will be able to buy a similar condition car with money left over for some extra work if needed/wanted.

But if your heart is in the car, it will be a fairly easy change over as the parts should be readily available at auto recyclers second hand. And i am sure some people will want the manual gearbox/peddles etc to put in there car to make back some money on the labor costs. You will need to change the peddle box, torque converter, transmission, maybe change over the flywheel and run a kickdown switch and pressure line to the auto and that will be about all you need.

I think you are all right, it would be sacrilege to convert it over. I will, however, get them to check the box for any play. I personally like a good solid movement between gears and it could be that the box needs a quick once over to ensure everything is 100%

i have a solution to all your problems, keep the car and get the manual worked on like you are planing to do. And, earn more money so u can buy another 280SE, automatic, for the misses and just happen to take it driving every so often
