The "plugs" are ball bearings driven into the support and staked in place; never seen one come out. However, if a lockup support was installed in a non-lockup trans............

How much pressure? How about in gear? I'm assuming the converter is turning the input shaft (and it should since it checked out). If there is sufficient pressure either reverse or at least one forward gear should function. I doubt if both servos and both clutch pistons are all leaking enough for none of them to function. The valve body and converter should be out of the equation so lets focus on whats left. There could be a massive internal leak. The only time I've seen that was when the reaction support was loose against the front pump. Maybe it's tight but fits poorly? maybe a mismatch of parts? Again that should show in a pressure check. Are the rear clutch hub splines stripped on the input? Or is the hub cracked? Does the valve body set flush on the case? There isn't a accumulator blocker rod holding the accumulator piston just high enough to hold the VB away from the case slightly? My opinion is if it has good pressure there is a hard part failure. If the pressure is low you may have to do individual air checks while dissembled to find the leak.

Hey thanks again everybody. I checked the front servo in high gear before I pulled the transmission out and it had a touch over 140 lbs on it. The converter said that was plenty. I just pulled the transmission back apart and all the balls are in the support. This darn thing did this to me all of a sudden. Was moving and shifting fine and then nothing ? I did notice after getting it back from the transmission gut the first time that it seemed to hold onto 2nd gear a little after I shifted into 2nd. All gears worked fine though.

If it has 140lbs it has to have a hard part failure. How does the input shaft feel when slid into the converter by itself? Disassemble the rear clutch and inspect where the shaft fits the clutch hub, make sure it didn't crack in the center. I'd take a good look at the back half as well. planets, sun shell, etc.

I pulled it apart but didn't check the clutch packs. The planets seem to be fine. I will check the input shaft. I will try and upload a couple of pictures of my support after I unbolted it .

Does this look okay, I know a little fuzzy but how about the wear ?

Take better pictures - can't tell how bad the support face is where the rotors ride. Also there are 4 balls pressed in to the perimeter of the support. They are visible in Kunkels picture. Your bottom image shows one for reference - it's at 11 o'clock - there should be 4 total. Plus maybe it's the picture but the end of the reaction shaft seems pretty shiny - it shouldn't be.

I will try and take some more. How about the cracks in the surface ?? Are they supposed to look like that ?

The two "cracks" should be small "V" cuts if you look closely. They are there by design. Those appear in your image at 2 and 8 o'clock.

Hey guy's still working on this darn thing.
Could the pump still be faulty if it had 140lbs of line pressure on the high gear servo ? The fluid was coming out of the cooler lines pretty good also. I am running out of options with this thing. I know it is not the valve body or converter now. I have pulled it apart quite a few times and no mechanical damages to any of the hard parts.

Have you checked to see if the cooler is plugged?

Yes , I have even bypassed the cooler to make sure.. I did notice that my converter had very little fluid in it the past couple of times I pulled it out..

I ran into a similar issue with my 727 recently. The seal rings on the input shaft were blown out and the transmission acted as if it was bound up. Car didn’t want to go into reverse and with throttle application it would try to move by would just creep. Did the same in forward gears but not as bad. I bought the trans complete from a very reputable torqueflite specialist and when it was put together it had a lock up input shaft in it. The input shaft diameter was smaller in the seal area then the stator and kept blowing the seal out. Both pieces were replaced by a different shop after he found the issue and transmission is Golden now. I too noticed a small amount of fluid in the converter and was told the seal leakage from being blown was directing the converter charge elsewhere in the trans. Guy told me that the blown seals was causing the bands to be constantly applied essentially binding up the transmission.

Can't seem to get a consistent answer from you - previously you mentioned when you pulled the converter it had plenty of fluid. Now you say it had little fluid the last "few times pulled". Which one is it ?

A partially filled converter will get you EXACTLY the issue you have. You did not reply as to if you checked to see if the perimeter balls were in place on the support. You can have normal line pressures but if the converter circuit is open you will get a slipping feeling. One of the balls on the perimeter is for the converter charge circuit.

Also you say you have good cooler flow - but have you measured it? With a normal 3/8" line disconnected at the return - rear fitting at the trans you should get at least a quart of fluid at idle in about 10-12 seconds.

I appreciate all replies and , yes the converter seemed like it had plenty of fluid in it to begin with but since I started checking it it seems really low on fluid. The perimeter balls are in the right location and not missing. I tried the cooler flow it it was pumping really good. Just a couple of seconds started filling my drain pan very well.

Sprayed 416 I will check the seal rings too. Thanks !!

I know from watching a kid pull a 727 out of a B van about 5 times that if you put a lock up reaction support in a non lock up transmission the converter will not fill.

Mentioned 17 posts up - see Kunkels image. Hopefully the op checked for it - 👀

Thanks but it was checked out and was running and moving just fine for a few miles and then nothing.. That is the same support that has been with the transmission for a long time. None of the balls were missing . Thanks

I have a good friend that said he would sell me his John Cope built transmission. I may be selling all of the parts out of this one if I can't find the darn problem.
