4l80e shift kit ? about the check ***** we are puting in the transgo hd2 kit. the instructions show us where to put the "7" check *****. problem is there are 8 in there now. the 8th one that they are not talking about in the directions is right next to the acumulator cover. to make things even more confusing if you look at the crappy pics that came with the instructions it looks like there is a check ball in that location.
do we leave it or get rid of it?

I'm pretty sure you are talking about the location that doesn't get a checkballs, even on a stock rebuild ATSG says remove it.
Let me see what I can come up with to get us on the same page...

With that kit they have you leave 1 ball out. It is the one by the front band servo. There is one other location in the case very close to this position that in early models had a ball as well. Do not install a ball in either location. Follow the directions and you will be fine. Vince

thanks for the quick reply. since i got you guys on here i got another one.
the last page of the instructions is for upgrades "if the trans is apart". we are a little leary of taking the front of the tranny apart but it is out and on the bench so we could.
what do those springs in the direct clutch drum do? is it worth taking the tranny apart to do this mod? also shows drilling a hole in the pump stator, drilling a larger hole near the front seal and lastly puting in a new intermediate snap ring.
i didn't do any of that internal stuff in my truck and got into the mid 10's at 5000lbs. how important are those last few "internal" steps?

Don't drill the hole in the pump stator.
The drainback hole for the seal, I've never seen one blow on a 4L80E, so I don't do that either.
The HD direct return springs are to prevent centrifugal apply of the directs. If this is a sub 6000 rpm combo, don't worry about it. I usually drill a bleed in the drum in lieu of the springs.
The snap ring is good practice but if you don't set the 1-2 shift to kill, it should be fine without it.

+1 on not drilling the large holes in the pump. Not needed. The small .040-.050 hole for full time lube is ok to do.

Maybe not an issue with the 80, but you guys know the converter charge pressure issues with the 400s and how that mod can make it worse.
, this should be fun.

that pic of the instructions if funny. it is almost the exact same page but ours doesn't mention leaving that ball out and also doesn't say where that washer goes for the "new 4th bolt". i wonder if out kit has been sitting on the shelf for awhile.
