Is this torque converter a good one?

OK I have a Dacco F-63 torque converter brand new in the box I was gonna sell it because I thought it was a explorer unit but looking at their catalog I'm not so sure.
It seems to fit the 03 Marauder, 03 Mach I.... I know the Marauder is supposed to be a good TQ but I'm a little concerned that on the box it also lists a 3.8L town car on the sticker... Is this a good one or should I just sell it off and get something else? I'm guessing either way I am gonna have to change my flex plate.

Here are the specs:
11-1/4" Diameter, 1.375" pilot, 31 spline, four stud mounts on 10-5/8" circle modulating clutch type unit.

And the cars it says it fits.
Ford
1996~2003 Mustang 4.6L HO
2003~2003 Mustang Mach 1 4.6L 4V
Mercury
2003~2003 Marauder 4.6L 4V SC
Lincoln
1994~1995 Mark VIII 3.8L
1996~1998 Mark VIII 4.6L
1998~2003 Town Car LTS 4.6L (will not fit non LTS cars)

And the catalog pdf (pages 17 & 24)

First, you can't get a Town Car with a 3.8L, they only came with V8's 5.0L & 4.6L and Mark VIII's only came with a 4.6L.

Second, if it's an 11.25" heck yeh, it's a great improvement over your stock converter!

Third, you need a different flex-plate because it won't bolt up to the one you have - you can get them off ebay for $25-$35 all the time. You need a flex-plate from a Mustang GT, Mark VIII, or Marauder - basically anything you listed in your list!

By all means, use it! You won't be disappointed! F63 is a great converter.


FWIW, I'm using a Mark VIII TC in my Bird right now which I believe is the same converter you have there.
It is equivalent to a stock markVIII converter, it is an upgrade over the 12 inch unit for sure.

Thanks that's where I was confused by the box especially since the previous owner said it was for a explorer... I think I am going to measure it to be sure. And yea I already knew about the fled plate change. I only paid $60 for it a few years ago and I only realized it wasn't the explorer tq when I started researching it to sell it on eBay lol! I do have one more question for u guys with this tq is my trans gonna freak out is there anything else I need to do? That's good to know Btw Alan.

Thanks guys.

No and No, and you're welcome.

Thanks rick I kinda figured that but wasn't 110% sure. This is a little looser converter so I am assuming I'll loose a tiny bit MPG around town. I'm guessing its not real noticeable.
Eh, not much. In my crappy tune the converter stays unlocked in 2nd and I didn't really notice a drop in economy; it was about 20 before and after. With a better tune the converter will be locked in 2nd and your city MPG will go up.
Shoot, my average on my TBird has gone UP with all the mods I've done. I average 26 mpg - that is combined city/hwy since I just check it when I fill the tank. I have that same torque converter in my 'Bird (that was one of my mods - they're in my sig).
Bit off topic on the MPG but I always took the motorcraft fine wires at face value when I was told not to gap them because they are "factory set" and it might mess up the platinum tips.... I 've always had a rich problem, made like 16mpg city and not much power at all at idle... Pulled them today.. Yea after being in the car for over a year they were all around .043ish... The new plugs I went to put in I checked and sure enough not one over .044. I gaped them to .054 and gee no more rich problem way smooth power band and much better idle and off idle power.
Since I got Alan and Rick hostage on my page here.. :) The trans I am running is the stock 94 (and it is a solid april of 94 build date). It was rebuilt less that 5,000 miles ago but I don't think the guys who did it did much besides replace the frictions and I believe the sun gear and bearings in the tail. It has the typical whirling noise in 1st gear taking off. What should I look out for on the 94s? I know this first year had some issues but what specifically should I address? I am asking because I am obviously going to change the TQ to the marauder pretty soon and might as well do it while I have it out. I am also planning on dropping the tank to fix a leaky crossover tube, converting to rear disc brakes, and maybe if the Mark VIII pumpkin if money allows. So any other suggestions are welcome.
I bet they didn't replace the sun gear. Pumpkin is cool but get 3.73's in it for performance and get it tuned.

I would tend to agree with you Alan judging by the whirling... But the trans was grenaded when they got it if you turned the drive shaft it would grind in neutral. And I believe it was in the estimate. But yea they suck they couldn't even figure out the MLPS issue.
