I will need to replace the A clutch drum in the 5HP24, ZF revised part number 1058-270-040. The ZF part is both expensive and backordered.

Who makes a high quality aftermarket A clutch drum for these transmissions? There are a few options I found online:

One from DACCO:

one from cascade:
ZF 5HP24 Heavy Duty Input A Clutch Drum
The version from cascadetransmissionparts seems to be lacking the groove for the snap ring? I am curious as to how the contents of the drum will be retained in place without said snap ring?


And one from powertorque:
ZF 5HP24 5HP24A 01L TRANSMISSION "A" CLUTCH DRUM NEW REINFORCED UPDATED DESIGN FITS '96+ REPLACES 1058-270-040 - The American Powertrain Warehouse

Please let me know if you have experience with any of the above, be it positive or negative.


Also, please let me know if you have installed transgo 5HP-24-PR1 presssure regulator upgrade, what was your experience?

 

I've still got to do one of these too...

There are others but these will give you some info.

 

You used the one from Cascade, right? Do they ship their special snap ring with the drum, or do I need to order it separately?

 

I actually bought mine from a local transmission parts warehouse. But it is just like the one from cascade that I posted. The one I got from the warehouse did include the ring. I assume the csscade drum would too. You might contact them to be sure.

 

Yes the one from Cascade came with the ring. There is no grove to weaken the wall. It has an alligator style ring with a video that shows how to install the ring. Really quite simple.
