After thinking about this.. I believe I have brought this on myself.. I never had the conv cleaned out and all my problems seem to be trash getting into the system... I have all the gears right now but trash is sticking stuff(VB and gov).. I chanced it the first time and didnt have it cleaned out... its the same conv in all of the builds

Hopefully this will be my last question...the trans I have on the bench is the JY one that I changed the pump on.. that trans didnt have reverse.. now when I opened it up I see that both of the nylon rings on the input shaft were torn up... would this be the cause of no reverse.. I think it is but I want to ask and make sure.. everything looks like new in it.. all the fibers and steels.. everything... I opened up the OD and those look great also... so am I correct to think the nylon rings would be the reverse issue... thanks much guys... Im sending out the conv to have it checked and cleaned.. I will clean out the cooler and lines

I've always used the steel stepped rings.

Yes the rings will cause no rev. and 3rd ask me how I know lol. P.S check the 3rd gear clutch pack to make sure it didn't burn the fibers. Exact dactly!

If you are talking about the small rings (about 1" in diameter) that are on the input shaft, they are the feed for the rear clutch that is used in all forward gears, not reverse. If you are talking about the larger rings that go on the pump, those feed the front clutch which is used in high and reverse.
I'm talking the 1" or so on the front of the input shaft... I thought that ended up messing up reverse.. I was sure I seen this same thing on a 727.. but I dont know much

Mike, the 2 sealing rings that you describe on the input shaft seal on the inside of the front pump housing and are for the rear clutch, which is applied in all forward gears but not in reverse. There are 2 rings mounted on the front pump housing that seal to the inside of the front clutch drum which apply the front clutch in direct, O/D, and reverse. In reverse, the front clutch and the rear band is applied.
You should be able to check both clutches sealing rings and both drums piston seals by air checking the front pump and drum assembly on the bench.

Sorry I thought you where talking about the stator support Nope... the 2 seals on the input shaft.. the reaction shaft support has 2 metal locking rings which is on the back of the pump..they are fine.. looks like these 2 seals, seal on the ID of the reaction shaft support

I will clean out the cooler and lines Mike, check out the replacement pump. Years ago my dad had a 727 rebuilt for his truck. The builder was a low buck trans guy, who replaced the "worn out" pump. When we got it installed, it didn't have reverse. It seems to me IIRC it also needed a lot of throttle input to get it to move in forward gears. The builder couldn't find anything wrong with it and basically told us we were SOL. We tore that trans apart at least a half dozen times, and everything looked right, until I noticed the front drum was lightly rubbing the back of the reaction shaft support. It turned out that either the builder ordered a lock up pump for a non lock up trans, or the pump was incorrectly boxed and he didn't catch it or know the difference. We found a used pump in our stash, put it in, and the trans works to this day. I know yours is a lock up. I'm just wondering how our experience would play out in reverse if your pump was actually for a non lock up trans. Could be worthwhile looking in to.

Figure anything out yet, Mike? Just got the final parts today... I'm putting it back together tomorrow.. but I am sending out the conv to Ultimate in a few days to have it cleaned out and looked at EDIT I think I have this figured out.. I think with the rings on the input shaft messed up that it had just enough pressure to go forward(but I never left the drive way) but not enough pressure for reverse
