Piston Slap: Double A (Beep! Beep!) Em, Cee, Oh…

Greetings All-Knowing Sajeev,

I am looking for some insight on an ongoing issue with my workhorse. I have a 2003 Ford Focus ZX-5 with 160,000 miles. A little bit over a year ago, I had Aamco rebuild the automatic transmission on my car for the tune of $2500. Apparently, my car seems to have an appetite for transmissions, I’m on #4 now (original, warranty, junkyard, Aamco).

Lately, I noticed my car was leaving large puddles of fluid on the driveway, I checked underneath it, and saw fluid was accumulating around the transmission pan. I took my vehicle to my mechanic and he showed me what had happened. It looks like whoever worked on the transmission last (Aamco) had attempted to seal a crack in the transmission housing with silicone. From my understanding, silicone will not stand up very well to the heat and corrosive properties of ATF.

I passed by Aamco and they inspected my car, they acknowledged they had attempted a repair during the install. The owner of this Aamco franchise advised me that I would need a new transmission case and with parts and installation would cost me over $800.00. I’m a bit pissed because if they knew it was cracked, while the transmission was out, this part could have been replaced, now I have to go through a similar procedure to get this done again.

I really don’t feel like spending $800.00+ to get this done considering the age and wear on the vehicle. Should I:

1. Try one of those additives that claims to fix leaks.
2. Drain the transmission, clean the area, add JB Weld, and hope for the best.
3. Have the crack welded.
4. Try to find somebody else to do the job cheaper.
5. Listened to my father and avoided Aamco.

I’m mechanically inclined but my skills are not advanced nor do I have the space and room to do this job myself. Besides the transmission issues, the car hasn’t given me any issues, the engine runs strong. I do have a little bit of sentimental value for the car since it was my first “new” car I ever got. I do I.T. work which requires a lot of driving and the car gets decent mileage.

P.S. Driving my Dodge Magnum R/T is not an option since it would eat me out of house and home gas wise.

This isn’t the first time I’ve heard of problems with an AAMCO transmission franchise. Or, heck, any franchised service shop. Even worse, this is the second time I heard about a rebuilder cracking a transmission case.

What is the right move? Franchise owner eats the bill and hopes you remain a happy customer. If this only happens via running it up the AAMCO channel, so be it. Hit up their Twitter or Facebook accounts and ask the store owner for his regional manager. If it’s not too late, go do that.

If AAMCO doesn’t care, well, you are SOL. There are plenty of reputable rebuilders that dropship refreshed unit to a recommended installer, complete with a good warranty. I’ve heard good things about Jasper and the B&B previously agreed. Or get one from the junkyard and hope for the best, again. I’ve personally had a great Ford AOD rebuilt from a franchise shop, but I interviewed them, inspected their shop and asked them detailed questions about their AOD-skills. They passed the test and that made me happy.

Since you do like the car, I suggest getting a quality rebuild. And if there’s a local shop with a good reputation and extensive knowledge of Ford specific transmission issues, give it another shot. Because the aftermarket usually fixes all the weak spots in transmissions, combine that with an aftermarket ATF cooler and you’ll be set for many years to come.
