1972 Fury III ... closer to roadworthy.. now for the Transmission

[Davea Lux]

Isn't this the guy who dug the broken bolt out?
If not a small block the super been trans will work.

If this was the car with the 360 that had the broken bolt, yup it is the small block, been a lot of posts thru here lately, can't remember them all.

yes that's me....gonna stay with matching numbers so if the fluid and filter and band adjust dont work I am just gonna bite the bullet.....I think the disease has taken hold and I can't help myself from loving this dang car....uuugh

The valve body has a fair number of small parts that can be mis-installed. I would leave that much alone if you are not up to speed with valve bodies. Drain and remove the pan and see how much accumulated crap is in there. If there is a lot of black or metallic residue on the bottom of the pan, most likely your transmission is toast. If it is not real dirty, replace the filter and do the band adjustment and go with fresh fluid in both the transmission and torque convertor. While the pan is off, be sure to check that all the valve body bolts are properly torqued. A clogged transmission filter can cause slippage, but usually by the time the filter is clogged with debris, there is damage to the bands or clutch packs. Changing the fluid and the filter and a routine band adjustment might get you by for a while longer. Let us know what you find when the pan is off.

Dropped the pan... the pics below are what I found...haven't drained the TC yet.. looks like there was about 1/2 gallon (2 quarts?) So far... the white cardboard is the scraping from the pan (maybe 90%)...I swirled the fluid around in the drain pan and for sure saw some small metal pieces..
How much is too much? Certainly the fluid looked really dirty. I'm a little afraid of the band adjust but I think I'm gonna go for it... and drain the TC and close it up...then some Lucas and fluid.
How do I refill it? With or without empty TC...

Dropped the pan..here are pics of what I found...going to drain the TC next but so far looks like 2+ quarts in the tranny. The white cardboard is the debris from the pan I scraped with my finger so maybe 90%of it.
How much is too much? Gonna take a deep breath and try a band adjust and drain the TC and close her up....fingers crossed..
What is the correct torque for valve body?

Pics...also, when I swirled the dirty fluid in the drain pan, I saw some metal-looking shavings at the bottom...I don't know how much is too much

The transmission is showing a fair amount of clutch pack and band wear, filter appears clogged. Do the band adjustment and replace the filter and reinstall the pan. Drain the torque convertor if it has a drain, some do, some don't. If there is a small access cover on the sheet metal cover for the torque convertor, there will usually be a drain plug on the front face of the convertor. No little cover probably means no drain plug. Fill the transmission from the dipstick tube with 4 quarts of oil and start the engine in neutral. Let it run and check the oil in neutral and add oil until the dipstick shows full. Run the car thru all the gear positions and end again in neutral and recheck the oil, add as necessary to bring back to full. You are now ready for a test drive to see shat you have left for a transmission. If it does not slip, you are probably good with this unit for now. If it still slips, well, at least now you know the transmission is shot.
If the torque convertor does not have a drain and the transmission does not slip, you should consider changing what oil you can again to flush the system. You can do this easily by unhooking the transmission cooler lines from the radiator and attaching a short hose to each line into a drain pan, start the car and let the oil flow until it stops and shut the car off. Reattach the lines and add 4 quarts of fresh oil and restart the car and refill as necessary with the procedure above.

trans is on it's last legs. new filter, quart of lucas transmission fix, refill with fluid and drive it till it no longer goes. it could last months or years.

thanks Dave... what do I use on my torque wrench for the adjusting nut that is square? I have a 3/4 drive torque wrench...will using and adapter to reduce it change the torque of 72?

will do....crossing fingers here....not gonna put a lot of miles on this car so for now if I can get some life out of it that's great...probably most important is that it can move itself around and a few cruises...

3/4 Drive is serious over kill for this job, torque 72 inch pounds (equals 6 ft pounds) for the adjustment, I would buy one of the cheapie inch pound torque wrenches for about $15 at harbor freight. The square adjustment nut takes an 8pt socket.

I had seen that video a few minutes ago and I am confused about the number of turns... in the chassis manual under specs, it says back them both off 2 turns.. in the video he does 3 and then 1 1/2 turns... heading out to harbor Frieght

If you have the FSM for your '72, do what the factory manual says as far as the number of turns. There is a fair amount movement built into the servos for the transmission. The important thing about the band adjustment is that the band does not drag after you are done adjusting it. BigBlockDodge explained how to check the adjustment above for drag. If you have done the adjustment correctly, the drive line will turn freely when you are finished.
