Default PDK to MT conversion

With PDK replacements being very cost intensive, has anyone thought to swap to a manual in the event of failure?

i’ve luckily had no problems with my PDK, but since I prefer a manual transmission I wonder if that would be an option should any issue arise.

I know this swap has been done in the 997 GEN cars but I’ve never heard of it in a 991 outside of an RS car that was done recently

it can be done, sure. like anything, it's just a matter of money. in this case a lot.

you're still looking at ripping out modules, reprogramming a bunch of stuff, and adding a not insignificant amount of hardware to the car to facilitate the swap. if you're paying someone to do it, I suspect the MT swap will be more costly than just a PDK replacement.

^ Exactly, better off just purchasing a manual, or enjoying your PDK.

Not impossible, but way too much of a headache, you would need an ECU reflash, new center console parts, shifter, cables, transmission, clutch, pressure plate, various brackets and bits and pieces, clutch pedal, plumbing from the master cylinder for the clutch and a VERY creative tech who is willing to take on this project.

My guess is you will never get it 100% working as OEM spending less than 30k + in parts, labor and stress.

we just watched the Seinfeld episode "The Conversion" last night. i think going to MT would be easier than going to Latvian Orthodox and when you're done you'll have the kavorka!

yeah that's going to be cost prohibitive I think, for that type of cars... After many years, people figured out how to to it on "early" paddle shifter boxes on Ferraris F1 boxes and M3s SMG and it's very popular... Those were single clutch automated manuals and they could shift pretty fast but somewhat jerkily for daily use and the logic for when to shift was very very bad compared to PDK, which guesses right 99% of the time. But that is because they were essentially manual boxes with a little robot-elf doing the shifting in the nose cone.. Matter of fact 2 day ago I got my E46 M3 back as a manual (from SMG) after a week away - the guy I used does this as his full time job and had a months long wait list - they add a pedal (well 2 if you consider they replace the brake one to a smaller one), some piping for the clutch hydraulics, and machine the front end of the gearbox to become manual instead, add a shifter, reflash the ECU, boom - it's absolutely awesome and completely changed the car for me (but SMG sucked big time, PDK not so much!)

In the case of a modern true dual clutch box like PDK, you have 2 separate input shafts I believe one with 1 3 5 7 and the other with 2 4 6. Where I'm fuzzy and I hope someone can expand on this, I think the manual is largely similar to PDK in its Layout but only one clutch presumably, and a Rube Goldberg device called MECOSA to translate the H pattern shift motions into something the box understands (someone please correct me if I'm off base), so maybe one day some enterprising tech will make it happen but there's gotta be more internal differences because dual clutch vs single - some ratios too, I hear? Interesting topic ! Right now the risks of failure and costs of replacement are probably similar due to the similarity of the internals (remember the reverse light switch we're all under extended warranty for now? affected both).

The R&T article said "About $45k".

That being said a totaled donor Carrera could work for us, instead of new 911R parts.

Just because something “can” be done doesn’t mean it should be done. Just sounds like loads of cost and possible issues and then the car is yours for life.
Better off trading at some point.

This is amazing! How many labor hours were required?


Glad I made this post, I think we just uncovered the first non-RS PDK to MT conversion!
