Your 'Guide' to the 727/904 transmission

Obviously a joke.

He’s been a FBBO member since 2015. Hee hee, I’m sure he knows his 727’s, or at least knows in his heart that ‘thems are the best!’

Ya, I do think I know 727's pretty well. They are a great trans. I'm sure other guys know a lot more though. I have a few combinations that I know work really well for drag racing and a couple for HP street cars.

Gotta pull the 727 in my coronet this winter. Any suggestions for a street 472 hemi?

You know the 727 is an excellent piece.
Back in the day the drag racers started going to a Glide. But with those you need to replace everything inside the case with aftermarket super duty parts to handle 600 HP.
A 727 just needs red bands & clutches or equal and a good valve body. Just my opinion.

See you know your stuff a tad.

The bad is for gas Milledge now a days.

If you are going for gas mileage, 440 wouldn't be my choice. Get a real light import with a little 4 cyl.
Although I built a fairly HP 360 to replace the 318 in my van/tow vehicle that got at least 3-4 MPG better than the 318. So....?

Hey Mopar Geniuses', new here and could use some help. I've got a 400BB in front of a 727 push-button trans (in a 31 Tudor Model A). Casting #F2464424 0967415. The Dodge dealer and local trans shop can't tell me anything about the history of this. Long story short, the speedo cable was leaking at the trans, and someone had siliconed it, and the cable needs to be replaced (leaking badly). After having it apart, it doesn't look like the ones online with the availability to turn it to set different speeds. On the gage side, it's a 5/8 ID push on with small square inner cable (6' long). I have a feeling this cable might have been made (thus the leak). Any help would be super appreciated! Cheers, Mike

I hope this thread is still watched.
I am looking at replacing the original 5 speed manual transmission with a 727. Space is limited, but the Tucker specs list the 727 and Allison as options. So Tucker must have used the short tail and yoke that used used in trucks and vans that used the 318 engine.

I just want to be sure this will fit, but so far I have not found anything online that gives the measurement of the overall length of the truck Loadflite transmission. The space I have to work with is roughly 26"
Anyone have a 727 shorty to measure to end of yoke????

Google says 34 3/8"

Ya, I saw that measurement, and what then is the long tailstock measurement? It seems 34 3/8" is closer to the long stock length.

That IS the whole thing, bell housing to end shaft seal.

23 1/2" - 35" = 11 1/2"

The machine I'm working on has a space of about 26" ~ 27" to squeeze in the 727 transmission. The build sheet says the machine has three options for transmission. The 5 speed standard, the Chrysler "Loadflite", and an Allison. Back in 1975 the Allison would have been the AT540.
I don't have a 727 shorty to measure, so I'm wondering what 727 tail stock these guys were using to make the Loadflite fit in that space?

 

[YamaDooPolCat]

I found what I was looking for.
Took a picture.
The tail stock is about 8" long
