That is perfect, thanks.
 
My spare valve body I'm switching out has the bb mod. I just installed a superior shift kit and the bb was part of the kit.
 
So just an update here. Driving it around a little it seemed I have a soft 2-3 shift and third didn't feel quite right. So I tore into transmission and re-checking everything. It all looks good and I have the 0.015" per friction clearance on the direct and forward clutch packs. Is that still a good rule of them? 5 on direct and 4 on forward. If I need to change it now is the time. The ATSG calls for much more clearance than that which is why I'm a little concerned maybe.

Actually just measured again and they are pretty tight. Forward is .035" and direct is ~.060". Is this too tight?

Direct pack:

Inspected the OD clutches and they all looked good too.

If this is a VB issue I may change to a 47RE OD housing and VB built buy someone. Can anyone say exactly what all will swap from the 47rh OD to the 47RE OD. This will also stop my leaking t-case issue and will allow a billet output if I desire.

Looks good! I'm rebuilding my 47rh right now and I got (6) .61 frictions and (6) .070 steels to fit in the direct drum with a stepped/ machined plate with a thin snap ring left .015 clearence per clutch. Took a stock .280 plate and stepped it down to .148. Sorry I don't have a number on the snap ring thickness.
 
Well I'm guessing mine are a bit tight. Anyone else??

On a full manual VB does the position of this kickdown/throttle valve adjusting screw matter? What will this impact. Currently it's not even touching or close. Should it atleast be touching?

If I screw this in will it act like a "constant pressure" or it would essentially be the same as zip tieing the TV cable at 80% ??

Also this is the line pressure screw I'm pretty sure. How many turns in from all the way out should it be?

Transmission is back together. It's all a little on the tight side but a few guys have assured me it's ok. End play was around 0.110".

Final end play was .110? that seems like way too much to me. Im sure the other tranny gurus will chime in soon.

Measured by lifting on the input shaft. It's on the tight side of what ATSG says I think.

Any thoughts on VB?

Maxing that tv lever will keep the trans at a constant line pressure. Start there and throw a gauge on the trans to see what pressure is at and then touch the line adjustment if you need to.

Thanks. I'll start with that then.

I set end play tighter then that. .025-.060 typically

Hmm, so would you suggest getting a thicker washer between the input and intermediate? What is the down side of more end play?

I'd leave the endplay where you have it. Mine has been at .090 for a while with no bushing issues.
 
Ok, maybe I'll just run it and see how it does. Don't really want to take it apart again lol. Even though they are pretty simple...

Thanks again CompD for help!
