Piston Slap: Justy-fied Freestylin' Over CVTs, Part III
I am planning a transmission swap in my 2006 five hundred from a 2WD CVT to the offered 6speed of the same vintage. So far as I have discerned, I will need the trans, flywheel, axleshafts, computer and harness. A few compatibility questions though, trans mounts? speedo cable? Shifter and/or linkage? How about the PCM that controls the trans. They offer a few different ones, specifically:
- ID 5G1A-AJA
- ID 5G1A-APA-APB
- ID 6G1A-MB-MC
How about any sensors on the engine? Will the computer have to be flashed to my vehicle? I would like a clear understanding as to which is the correct PCM for this application and why before I start amassing parts for the switch. I would like to put together a package deal for better pricing from the local yard if possible.
Thanks for your insight and I would like to do this as soon as possible.
Does this mean people are crazy enough to actually follow my advice? Damn son, this is a little unsettling: compounded with the chance you’re better off buying a regular Ford Five Hundred without the dreaded CVT! Time value of money, you know.
But, to answer many of your questions, see the link in the above paragraph. And since Piston Slap will never replace a proper model-specific forum, a few quick answers to what remains.
1. A few compatibility questions though, trans mounts?
No clue, cross-reference parts at the Ford dealer or on the forum.
2. Speedo cable? Shifter and/or linkage?
3. How about the PCM that controls the trans?
Get the PCM that came with the donor car. You might still need a re-flash by an SCT-savvy tuner, but nobody will know that unless they’ve already done the swap.
4. How about any sensors on the engine?
Having been around Ford engine controls since the bizarre EEC-III system, I seriously, seriously doubt this is a problem. Engine sensors are not unique; pop the hood of a V12 powered (i.e. two of your motors welded together) Aston Martin and you’ll see what I mean.
5. Will the computer have to be flashed to my vehicle?
Best of luck with the conversion! We want to hear the conclusion!

- Alan My friend has a Toyota Kluger (made in 'murica). A Highlander. These things are based on a Camry platform. I have driven the Kluger we had at work and I find them quite boring even for a SUV. An appliance. I hope this will deliver some driving pleasure. I found the Camry a better boring vehicle.
- Alan Most Lexii look good to reasonable.....................until you see the front ends with their awkward grilles. It actually would look normal on a GWM, LDV or any other Chinese vehicle.
- Tassos These last months, every day seems to be another great, consequential piece of news for Tesla, who does not just DOMINATE, it OWNS the US and FREE WORLD BEV market.It is the ONLY (repeat ONLY) maker that builds its huge best sellers at a PROFIT, ie, SUSTAINABLY. FOrd EV is bleeding 3 billion in losses. GM hides theirs, and I bet they are even HIGHER. VW has spent a huge no of billions and its ID series has been an UTTER FAILURE.Toyota, already 12 years too late, is yet to try. I doubt they will succeed to dethrone TESLA.
- Tassos Again: I never took VOlvo seriously in the last 20 or so years.Chinese Volvo-Geely has a dizzying number of models, I have lost count how many,YET its sales and market share in the US has always been DISMAL these last 20 years.It ranges from a pathetic 0.5% to 0.8% of the US market.For comparison, Toyota has 15% and GM has even more. Tesla has almost 10 TIMES VOlvo's share, with a PITTANCE of really TWO Models, the 3 and the Y, as the S and the X hardly sell any copies any more.So why do we keep reading articles about Stupid VOlvo?Because they have the best PR department of any maker.

Frank, please post the progress on youtube ® if you so choose to proceed.
I suggest another route: Remove the existing drivetrain and install a pair of Honda Civic engines (see Car and Driver circa 1984). This makes as much sense and will have the same effect on resale value. See you on "Dumbest Stuff on Wheels"!
