Beefing up a 727 trans!

OK, are you ready?......$920.66 just for the aluminum drum. Here's the link http://www.compperformancegroupstor...Screen=PROD&Store_Code=TC&Product_Code=123900

I'm sure you can plug that part # in at the Summit Racing site and save a few bucks, but it 'aint cheap! As far as Kevlar bands go, you should be OK if it's mostly strip driven but I would still remove that trans once a year for an inspection and to freshen it up in the off season. Also, the trans should be pulled for an inspection if there was any driveline failure (driveshaft, ring gear, axle, etc.) I'm far from an expert on automatic transmissions as I have only rebuilt four in my lifetime and this is my first 727 build. I would urge you to contact a professional for your application as the consequences can be disasterous! (See this link! http://www.forabodiesonly.com/mopar/showthread.php?t=2167 )

Both the billet steel or the billet aluminum would be far safer than the sintered iron OEM piece that has the tendency to explode when the overrunning clutch fails. With this in mind, the middle of the road kit on Dusterb318's link looks great unless your looking for a trans brake valve body. Give them a call, maybe you can substitute a billet aluminum drum for the billet steel. Also, ask them if the five clutch kit fits in four clutch retainer, which is what you most likely have (Unless it's a Hemi Trans!)

There is an excellent book by Carl Munroe on the 727 that you can use to build your transmission almost step by step and also has a few chapters on why the 727 explodes. Let me get the title and ISBN # for you after I get home from work.
