While looking for a tranny for the wife's Satellite, I found a complete 400/727 combo out of a 78 pickup. The tranny appears to be a typical 727 (not the short one) but has a fixed yoke on the end. I was told the yoke could be removed, and a slip yoke could be put over the output shaft, like a car tranny. Does anybody have any experience with these? It will be going in a 73 Satellite with a 440. Thanks in advance.

If only it were that easy ... if it's a 4x4 then the trans is not going to fit into your car with some silly backwoods engineering .

If it has a fixed yoke with a nut holding it on,I have never seen a yoke that you can just slip onto the shaft and make it work.You can use a pickup driveshaft that has the slip joint in it,but you will have to change the length of the shaft-more trouble than it's worth.Lot of guy's buy these engines and transmissions out of a motorhome.

That's a shorty alright, don't know about convert to slip spline.

So, is this the same as a motorhome tranny?

if you are changing a small block 727 to a big block this can work----first you use the original small block tailhousing with the mainshaft (big and small are all the same) then you put the big block main case on it and fill it up with magical stuff and you are good to go---no need to make alterations to cross member or drive shaft---bob

This isn't a combo that I already have, I had the chance to buy it. But I didn't realize that it was a shorty.

you can buy a $15 manual with a $120 kit from northern and do it yourself---when my son was 16 i threw that at him and he did it right then went on repeat his success numerous times----yes a tranny guy can spot other problems that a novice will miss but you always run the risk of dealing with a guy that needs to hit a home run on you to make a mortgage payment or pay back alimony and he always has a pile of worn hard parts to show you in case you ask----so if you have a 6th grade reading level you can do 95 % of the jobs--i even built the one in my 71 military powerwagen--bob

wont work, but the internals can be used..

I think I will take savoy64's advise, and try to do one myself. I have two 727s in unknown condition. One is from a 70 coronet, and one is a shorty out of a MH. Is it possible to build a beefy one out of the two?

Chrysler built the transmissions for their intended usage. So that means a 383 didn't get as many clutches as a 440, etc.
The motorhome transmission would be worth rebuilding because it is pretty heavy duty. You'd actually open them both up and use the tailshaft and tailshaft housing from the regular 727 on the MH transmission.
I believe the tailshaft has to come out from the inside so now would be a perfect time to do that, while you're rebuilding it anyway.

Post the numbers stamped into the side of the pan rail and someone here will be able to tell you what they are.

R.

I will be getting them out of storage tomorrow. I will post the numbers. I know one is from a '70 Coronet with a 2bbl 383, and the other is from a 440 powered Motorhome. But I'm not sure of the year.

I got them out of storage today. Where are the numbers located?

The part number is stamped in the drivers side pan rail, just above the gasket. Look here for the application:

besides the difference in tail shaft length the MH trans should have a 4 planetary gear set. The other tranny should have a 3 planetary gear set..

I checked the car tranny, which sounds right. But, the shorty has pk3893765 5058 3275. Can anybody tell me what it is? Thanks for all the advise.
