The guy at Dynamic said to check the reaction shaft behind the pump to see if the plugs came out ???? What the heck is that ? Help !!! 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............

No not unless I really rev it up. That is the only way I can get the wheels to turn at all. Forward or reverse just a little harder in reverse. 1. no trash in pan2. fluid not burnt 3. have pressure in high gear at idle 4. only moves when revved up in all gears. = converter is broken Joe 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. Doug

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.

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 ?

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 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.
