They're not strictly required though if you run across one, you can put it on...They're sold by Transtar for a few dollars apiece, I believe.
Awesome. I went with a kit from transparts warehouse with all the seals, steels, frictions, bearings etc. and plan on referring to the manual you mentioned for installation. I wound up breaking one of the little detents off the rear planet bearing, that seal from the forward clutch piston was bad and obviously the forward clutches. I cleaned every other part up and inspected them thoroughly. After seeing how it’s assembled, I’m not too worried about that gouge in the forward drum unless you think it should be replaced. Do you think the damage to that piston seal was really what caused my forward clutches to be turned into steels and me to loose 5qts of fluid? I’ve never seen a leak under this truck and my coolant looks good so I’m still questioning where that went. But if you say this rebuild kit should get my stepdad back on the road, I’ll take it slow, make sure I do it all right, and rest easy. At this point, i know im rebuilding it. I just want a tiny bit of peace of mind thinking the previous problem has been addressed. As always, thank you for any and all help. Hats off to you sir! (Nicktransmissions)

What gouge? Shoot a high quality picture of this gouge and post it

Why would you think a torn lip seal inside of the forward drum would result in an external leak?

But if you say this rebuild kit should get my stepdad back on the road, I’ll take it slow, make sure I do it all right, and rest easy.
Can you post a picture of the rebuild kit that you mentioned above? A link is fine also but a picture makes it a lot quicker for us to see exactly what you're buying.

You're welcome, man.

You're welcome, man.
I’ve never seen any atf on the ground under this truck. I’m trying to figure out how it got 5ths low in the first place. I was just asking if you think this torn seal was what caused it to be low and burn up the clutches. I’ve now started the rebuild and am checking clearances on forward and direct drum clutches. I’ve made a new post about it. As always thanks for all your help.
