Title: Sacrilege
Post by: Merc_Girl on March 01, 2021, 22:04:43
So
I know it’s probably of the upmost sacrilege to even consider this, and certainly not thinking of anytime soon. I’m just thinking of my latter years and thinking that perhaps a manual may be hard to use.

My question therefore is, is there a ‘modern’ automatic gearbox that could be installed in a pagoda? I saw somewhere on the forum something about the transmission tunnel is too narrow to accommodate a modern auto gearbox?

Just pondering ...........

Any ideas?

Katie

Hi Katie,

You could consider a traditional, old fashion Pagoda automatic.
I must say it’s very good.

Katie, big problems with a 230Sl engine converting since the crankshaft and flywheel would need to be changed or re-worked. These assemblies are "counter-balanced" on these engines and final balancing is done with the front counter weight, flywheel and crankshaft assembled and then balanced. Each component is counter-balanced to the other to form a balanced assembly. After balancing is finished you could install a pagoda automatic transmission. You would still need a lot of parts and work to complete the job. A front drive shaft, flywheel, torque converter, shifter, some wiring work and a lot more bits and pieces are some of the parts involved. In most cases it is not worth it, unless you have access to a complete parts car (automatic) with all the bits. You most likely are better to find an automatic pagoda instead. Nice article on you and the car in Pagoda World by the way. I share your background as an Industrial Designer by profession. Of coarse my other profession is Mercedes automobiles.  ;)

Somewhere, don't remember where , just recently, I read about a pagoda with a ZF Automatic???

I found it. It was in Gary's link he posted about the auction of Natalie Wood's 250SL:

. . . in other words, a slightly ignorant copy writer dressing up a celebrity vehicle article with terminology that may or may not actually be accurate, but sounds authoritative . . .

Thanks Joe about your kind comments about my article, bit nervous about writing it!!

Anyway, bottom line seems to be, don’t bother

I will attempt to start developing my leg muscles so that in older age I will have legs like a body builder so manual won’t be the worst of my problems 🤣🤣

I had a similar problem where Kate my wife had terrible difficulty driving my 280sl 5 speed so I somewhat reluctantly decided to sell it and purchase a 230sl auto. 
With the price difference i was able to have a full engine bay rebuild and some change left over.
Love my 230sl and all the extra chrome bling and have no regrets.  I use it a lot in the manual mode, Kate likes the auto and we both drive it now.

Love the bling on my 230SL as well, and also the finesse of the details, ie interior door latch and the door mirrors. All, I feel, a little more elegant, but then again I’m probably bias 😉

I wonder if a trend in the future is to put in an electric powerplant. this would be automatic.

Also just maybe it's possible your clutch needs some attention. We have a couple of manual transmission cars and it depends on the state of things (naturally) how heavy they are to apply. Never driven a stick Pagoda so no idea how light or heavy they are supposed to be to operate.

Funny, I have several cars and I was thinking the Pagoda would probably be the last one I'd sell as I aged because it's so easy to drive (4 speed manual).

Katie,

A few of us have zoomed past the 80 mark (years not mph) and are still effortlessly shifting our 4 speed stick models. My guess is that I will be taken off the road for some other, as yet unknown, reason before I get to the point of not being able to deal with the stick shift. 

Practically speaking switching out the standard transmission for an automatic is a no-go and after becoming attached to your 230SL, I think it will be difficult for you to make a switch.  So, just keep on shifting.... or buy yourself a second Pagoda with an automatic box!

Katie, it will not be your leg muscles you need to exercise but your knees.  If you have any farmer friends with utility tractors you can ask to exercise on those.  The clutch is used to stop forward and reverse motion if on level ground so you use the clutch a lot more than you would on a car.  Also more resistance so the knees get a good work out.

my 280SL is a stick shift and the clutch is very light. the main problem is having to constantly move the gear stick around town. I personally prefer auto also.

Way less work to just sell your Pagode and get one w/an automatic.

If you have money galore, you can do a full transplant.

Hi Katie,
I installed a 5 speed box in my 250SL auto. In the past 40 odd years, I have owned 4 automatic Pagodas.  I just loooove the 5 speed, should have done that years ago.

Anyway, you are welcome to the auto gearbox and all the associated parts needed. HOWEVER, I would not recommend the swap. I have no idea of the shipping costs from Cape Town to the UK.

It is not just swapping the tranny to Automatic. You need to work on the engine too.
On some other applications, I have worked with changing the master and/or slave cylinder to achieve a lesser actuating effort. I don't know if there are other parts from other cars available to would make this possible. But 'stick.." and JoeA have worked on so many cars, they may know.

Hi Katie,
I know I am a bit late to this party but I recall seeing an episode of Car SOS  on Television and the car they restored was a manual change. The owner had a condition that affected the tendons in his feet and resulted in loss of strength to push down the pedels of the clutch and the brake so the team fitting a pair of off the shelf vacuum servo units and made a few bespoke brackets to secure them...job done.

I hope this is of some interest.

Getting back to your original question the transmission tunnel is narrow but more importantly it is far too short for a modern automatic.  The transmission that would have been supplied with your car is a shade less than 18 inches (457mm) long and it barely clears the enclosed portion of the driveshaft tunnel.  Most modern automatics are pushing 36 inches (914mm).  Even Mercedes in later years kept the same automatic transmission in the W113 when they switched to newer models in the sedans because the newer model transmissions wouldn't fit.
