Alright, Mopar fellas- picked up these 2 trannies from a friend who said-"get these things out of my garage". They were there when he bought the house, just had'nt gotten around to getting rid of them. Looks like one is an all aluminum TF 727 with the ring gear on the Torque converter. Pulled the pan off, it's missing the pickup and screen, maybe some other parts, but looks really clean. The other is a TF904, has some rust on the input shaft, it's missing the speedo drive, and looks like there's friction material on the pan. Plus, he gave me a Edelbrock 750-said he put it on his Pontiac, and it was too much carb-but just what the Doctor ordered for my 401 Nailhead! CHA-CHING! I'm not looking to make any money off of these, just wanted to trade them for a set of steelies or something else I could use. What do you think they're worth? Are they just large, unwelidy paperweights at this point? Any help would be appreciated!
The 904s were essentially similar in design and reliability to the 727s otherthan the 727s were made of more HD components. 727s were standard equiptment for the big blocks and many trucks while the 904s being 'Standard Duty' were used mainly for the small block V8s and sixes.

Yeah, my slant six Cuda's got a 904. You should be able to sell 'em. Probably won't get much, but maybe help you towards your steelies. Find a local Mopar club and see if anyone there needs 'em.
Only difference I can tell you is that I can pick up and carry a 904 but I'm ******ed if I can do that with a 727. I did ask a ****** guy which was the best to use behind my 318 poly and he recommended the 727 cos he said I wouldn't have any trouble with it. He said the 904 has a tendency for the bush in the converter to come apart. A lot of guys out here build hot 318/340/360's and fit them in Valiant Chargers (a local car, not like the US model) and they came with either 727 or 904 so that might be where they got a bad name. swifty
commom Might pickup a 50 for them ..if you are real lucky go by local trans shop, see if they buy them for cores Drug a short shaft 727 (truck version) to swap meet after swap Gave it away one day so I DID NOT LUG the greasy piece of **** around anymore
If you were closer, I'd take them both. Yeah, around 50 bucks for core is av price, if a fellow needs one. Other wise take what you can get. 904 is just as good as 727 but won;t handle as much HP without work. I;ve got a 904 in my Dart and it works great, but I have done some work to it to make it more durable so it can handle the Nitrous.
Some 727's are worth more than others. The earlier ones were cable-shifted (aka "push****on" bucause of the push****on selector) and later ones used mechanical linkage to shift. '66 and later have linkage where '65 and earlier had cables to shift & actuate the parking pall. The cable-shifted transmissions also had an extra oil pump in the back so it can survive being backdriven (pushed/towed without the engine running). Additionally, '64 and earlier had a flange for the ball&trunion joint on the driveshaft, where '65 and later had a spline for the slip-yoke. Many people are after the '65 727 as it is the only 727 with a factory slip-yoke tail shaft and cable-shift. The 727 bellhousing pattern comes in at least four configurations: big block, small block, slant six (truck applications), and International. Almost the same for the 904 except no big-block pattern. AMC used them as well but I don't know if the bellhousing was the same as International or not... Since you said the 727 has ring gear teeth on the T/C, it came from a MoPar - the others had the teeth on the flexplate. Post a picture of the front and driver's side of it and it can be easily identified if you are unsure.
Another thing to look for is the input shaft on 68 and earlier are corse spline and the later ones are fine spline. You have to use the coresponding converters for each one. I'm not quite sure if you can swap out the pump for a later one. It's normal to find some sludge in the pan, as long as it's not chunks of friction material. The only thing missing would be the screen, there is no pickup. The screen is held on by three screws. I believe the speedo housings will interchange. Another thing is a lockup pump will not work in a non-lockup transmission. Don't ask me how I know that,lol. later shawn
