Which vendor has the most complete rebuild kit? What is missing from the kits that have to be ordered separately? Is one kit preferred over another because of type of materials?

Do the kits include the converter seals, O rings, etc?

I figure that bands never included, but what else?

I just don't want to piece meal this together and realize something is missing with half way through the process. I only want to go to the well once.

kanter give you everything except sealing rings
Max doent list a kit, you have to tell them what you want but have it all
fatsco missing a few sealing rings that I had to buy elsewhere.

Looking at a new supplier but I have not evaluated their kit yet. All three above use same modern clutches.

Troy,

What "sealing rings" are you speaking of?

I was wondering what I would get in the '51 Ultramatic kit from MM before I ordered it. Seems that every seal, gasket and bushing I will need is there as well as the steel and friction plates for the high range clutch and several piston rings. Had to search a bit on their site but you will find a kit at MM Kit


The P/N is Group 3.5051 cost $395, which is a bit less than Kanter's kit but doesn't have the re-build "Instructions". I figured I didn't need the instructions so why pay for them? Everything is on packardinfo anyway.

Judging from the look (- old/ original) and construction of the bushings in the kit, they are NOS. Piston rings may be NOS also, everything else looks new. The clutch plates are new, not refurbished and use the new friction material (- which I assume is the GM material? Troy might know if that's the case, but it is a light colour, definitely not cork).

There are two or three copper washers and also three copper rings (compressible) which I would suppose are the sealing rings you are asking about. At first inspection two look like they go on the large plugs at each end of the bell housing which hold the converter pressure relief valve / spring in place. They're the right size for there. Then there is an ATF drain plug copper washer and one other washer. And two small rubber O-rings. Gasket set looks complete including one for the governor.

Can post a photo of the parts if you want, let me know.

(- link not working - dunno why . . .)

I've had luck with Max's links if there is a details page associated with the item. Try finding the kit again and if there is a Details page, click on that and try linking the page that come up

Are all of those all inside the converter?

Larry, did your kit from Max contain those?

What Troy is showing in 237.jpg must be a '56 part . . . Looks like a different shaft design to me. I don't have that part in my 51 trannys far as I can tell. My MM kit didn't have such a part.

Also, as Troy said I see MM doesn't have a kit listed for a '56 Ultra rebuild, just kits listed for up to '54.

(And thanks Howard for the tip - that worked OK).

There is this kit listed on Max:
