Is It Possible ???

Does anyone here know if its possible to convert the sl 55 auto tranny too 6spd manual ?

ide think the car would have way more jump if it were to have a clutch and WAY MORE fun to drive.

dont get me wrong .... the tiptronic it has now is good .... but its not the same when u pop gears in manually on a power car like the 55.

Not sure if it's even worth the time and money for such a conversion. Just add a 6spd twin turbo beast to your stable.

You would first need to find a transmission to fit, many custom made parts, then doing the actual conversion. Ive heard of such things being done, and they ended up being in the $50-100k range. Get an SL65 and get the Brabus 730hp kit.

Buy a Porsche 996TT/997TT and chip it. AWD with 600+ HP will make your nose bleed on launch.
Converting the SL will be $$$$$$$$ because you will also need the ECU and a LOT of other things changed.

I bet the Germans can square you away for the right amount of money, however you might not be willing to pay what it may cost. Think about replacing the clutch every so often and who would actually be willing to do the labor, I could see if there were plenty of sticks running around town but that's not the case. It might be too much of a painful ordeal in the long run CHIEF.

In all honesty my men have, I just control them now. When you you increase in rank you don't get to do all of the dirty work as much, but that AT-4 will cancel Christmas for whoever it reaches out and touches.

We do a TCU upgrade that quickens the shifts, holds gear without upshifting better than the stock programming. It doesn't turn it into a manual, but it is better.

ya blowing up things would be a nice , even just to watch .

as for the mod ... how much does that go for and does it make a big difference ?

NOWAY will i sell my 55 for a porsche ...ewwww ! r u kidding me ..... this car has everything i need . ok ok its not stick woppideedoo!!

i dont even really race my car unless im going up north to the cottage where the roads are empty .... thats the only time i wished my car preformed abit more standard even though the tiptronic works great . i just want abit more pull when i switch gears .

If the mod is gonna be too expensive for something it will be abit of a different feel then MEH! wont even bother .

has anybody ever try this MOD ???
