Just picked up a 1967 newport with a 383. Engine runs but when placed into gear nothing happens. In reverse it moved about 6 inches very slowly then nothing. There is no movement in any other gear. It does have fluid and it is full. Any thoughts? I am new to all of this.....

I sounds like the transmission filter is probably clogged. I would start by draining the convertor and drop the transmission pan. If the pan is full of black gunk, more than about a tablespoon, the transmission is likely shot. You can try doing a band adjustment and replacing the filter as sometimes that will get you by for a time. If you still have nothing after the band adjustment and fluid/filter change, you need to rebuild the transmission. FSM gives good detail on how to do the band adjustment.

Did you check the fluid while idling in neutral? Try that and see the level it could be 4quarts low from sitting.
 
In the mean time, check to see if there are any GOOD trans shops in your area that "know" Chrysler TorqueFlite 727s. How much for a general rebuild using OEM-spec bands/clutches, etc., with a converter and cooler (w/lines) flush.

I suspect that if there's fluid in the trans and "nothing happens", even if the filter is restricted with friction material, a new filter might then indicate a worn front pump, etc. The band adjustments might be a diagnostic situation, but I wouldn't count on it fixing anything. Just my gut suspicion. And I might be wrong, too! Hoping that I am, but do the checks just in case you need a reman unit or rebuild your existing trans.

Just a normal OEM-spec rebuild is all you need. Letting somebody do "some little tricks" of their own can cause other operational issues, by observation. Maybe some upgraded friction plates or band, but nothing else. Get it running well and THEN do the shift kit stuff, if desired. B&M, TCI, and others have overhaul kits and such. Maybe even something in Mopar Perf?

Probably more to it than something that is easily fixed. Does it feel like it is trying to engage?
A band adjustment won’t do anything for for it as the bands only work on second gear and reverse.
My suggestion is to drop the pan and see what’s at the bottom. Send some pics of the slug. Also what colour is the oil and does it smell burnt.
There are pressure ports you can tap into to check what the pressures are. You can find this info in the FSM.
 
I checked the fluid with the engine warm and in neutral and the level seems fine if not a bit more full than should be. When shifting between the gears there is no feeling that it goes into any gear. The indicator on the dash does not move but watching the arm on the trans through the engine bay it does seem that the linkage is working.

Pardon my ignorance but what does FSM stand for?
 
You have a pump problem.
If you have first in drive the rear band is broken/bad
No second gear, front band is bad no high gear front clutch is bad.
Loud noises clanging, broken hard parts.
My guess is the front pump support is worn bleeding off pressure, or you have some serious contamination in the pan which means it needs to come apart.
You can disconnect the front cooler line and see if the converter is sending oil to cooler, anything but a solid stream with engine running see above.
 
Is it worth having it rebuilt or just purchase a remanufactured unit from Summit, Jegs or an outfit like that?

In general, best to try to rebuild what you have. Many trans shops have access to good used internal guts rather than purchasing new items, which can hel on the cost . . . for a normal OEM-spec rebuild. What the hot rod industry might supply will possibly be a hp-oriented unit that might not do well with your current application. AND you'll still need to swap out the speedo gears so the speedometer works correctly!

You're not needing "rocket science", just a good solid OEM-spec rebuild. IF the bands are broken, no big deal as they will be replaced anyway. If the front pump is worn out, then a good used one might be obtained by the shop. If one of the drums' outer surface has a wear pattern on it, that can be polished out, possibly. Look for a rebuild kit in RockAuto so you can get a ballpark price for that and what's in it, just so you'll know. Network with some of the local car enthusiasts to see where they get their trans work done. One shop might be mentioned more than others, plus which ones to stay away from. That means "face-to-face" rather than Internet searches!

When the trans is disassembled, the cause of the failure should be evident AND how to keep it from happening again. Could be several individual things or a combination of them. Just have to open it up and see. THEN talk price, warranties, and such.

Just some thoughts,

Waiting on a few shops to get back to me while trying to learn more about this car. The brakes have a leak in them as the fluid was almost gone in the reservoir. The brake system wouldn't be tied into the trans would it?

Completely different systems. Check the bottom of the master cylinder for fluid, that is usually the first place they leak. Next, pull all 4 wheels and inspect the wheel cylinders for leakage, carefully inspect all steel lines for rust and all rubber brake lines for cracks/leakage. You are probably headed for a complete brake system overhaul. If the master cylinder has fluid on the bottom of it, that is usually means that fluid is leaking out of the rear of the master into the brake booster if the car has power brakes. Usually this will result in a brake booster failure as well some where down the line. If this car has been sitting for a long period of time, most likely the master cylinder, brake hoses and wheel cylinders have deteriorated and should be replaced.

decided to et the car up and pull the pan. This is the results. Not sure what all this is but I assume its not good. The filter seemed completely clogged with this as well. I am headed to the store to get a new filter and gasket just to try and see if this works.

the gasket itself seems very thin, almost as if it was just some sort of RTV as there are places that looks as if it has squeezed out at the edges. Also the gasket is coming off in pieces and chunks. Not how I would have imagined the gaskets to have come off......
