99' f-350 7.3 diesel .......Ok yesterday I pulled up to the store -- left truck running in park.. came back out put it in drive .. nothing .. like its in neutral... but it did have low gear so drove it home slowly in low... fluid level good. Never had any problems before .. then all at once ??? pulled the pan today dropped the valve body .. found one of the 3 feed bolts a tad loose ( finger loose) .. tightened it back up ... now heres the problem . after dropping the accumulater plate i only had 7 ---5/16" Checkballs on the floor in the fluid puddle and all the info i can find on the web shows 8 .. but I cant find info on the 99' model .. anybody got the info on how many I should have ?? and location. I have found some pics showing 8 .. If i'm suppose to have 8 then I'm screwed.. if 7 which one do I leave out ? any one of you tranny guys have a spare 5/16" ball you could send me if I need an 8th one ? thanks ... gonna have to walk to work if I cant get this fixed quick...

 

You can get the check ball from Ford. My dealer keeps them in stock.
I have never torn into the 4R100, but I know on the 4r70w that you need all 8.

If your dealer is big enough to have a trans guy then he should be able to tell you off the top of his head. Its less than $2 for that part.

 

Don't leave any out, if there were 8 in there it will need 8 to operate. Once you get it back together will it drive with the shifter in 1, then move the shifter to 2, then to OD with OD turned off? Will it go through the gears that way?

 

Mark -thats what I am needing to know .. are there suppose to be 8 5/16" ***** in a 99' model or 7 ***** . I only had 7 ... hoping someone could tell me for sure ...

 

I have been all over the floor ... got a smooth clean shop floor under the truck and the other 7 ***** were all together . Makes me wonder ... is there a chance this truck could have had a tranny upgrade "shift kit " or something that would call to leave a check ball out and only use 7 ? I'm not sure ..anybody ??? I don't want to put one in and mess up something that was maybe already modified . But will be more than happy to find one and put it in if it needs to be there . When I bought this truck it already had the gauges for boost - egt - trans temp-- superchips programmer-- air ride-- vacuum assist brakes etc so thats why I was wondering if maybe a tranny mod could have been done that might have changed the checkball count... ??
