1990 300 sl change over to 5 speed info wanted
 

i wondered if it would be hard to change over a 1990 300 sl from the auto to the factory 5 speed set up

is anyone reading this forum familiar w/the differences between the two cars? can the swap be made relatively easy?

thanks

Why? The five speed sticks are quite available.

because my at may be going out and i thought it would be nice to change to
 

a5speed rather than rebuild the auto

Have you driven one? It isn't a very nice setup - bad clutch, long throw, dogleg shift pattern. I would try one if you haven't yet. The short answer is that it would be a big job, plus the parts are rare.

no havent driven one,will keep an eye out for one to try
 

and, so it is harder than putting a 4 speed in my old 55 chevy back in high school?

i would think that the parts are much the same as for a five speed in an e class or a 190 or c class.

perhaps the shifter might be different.

i dont know from experience but i would be surprised.

Ken, I suspect that the manual transmission cars have an interlock to prevent the car starting in gear without the clutch pedal depressed. Incorporating that interlock into an automatic car's wiring may present a problem so I'd carefully research the details before starting what appears to be a simple mechanical swap.

The transmission is entirely different - from an outside source. I forget who made it but it's the same transmission as in a Porsche 928. It's very sturdy - it just shifts like a truck. It was never very popular in a 928 either.

thanks, i didnt like the 5 speed in the 928
 

so i guess ill forget the changeover

now on to first gear start modification
