ok output end play is .020 , thats just shaft movement now if i push harder the guts = everything on the output shaft from the snap ring back , moves another .080 .... and other words i can push the output shaft and it moves the sun shell .080 .. my statement : if i put thinner selective washers that moves the STATOR SHAFT closer to the reverse drum ....

I checked a partially assembled trans (up through the sun shell) and while I didn't put a dial indicator on it, the output shaft might have .080 total play. It will be less when it is all assembled.
When assembled, the selective washer does NOT change the position of the stator shaft as the entire pump bolts to a fixed position in the case. Instead the input drum/shaft has some end play, e.g. .020 which is much less than the .100+ distance between the input drum and the reverse drum that you noticed.
You might find that the reverse drum has much less end play than you think once you have it all assembled. If you test-assemble without the band, it is easy to move the reverse drum back and forth through an access hole in the hole.

I was thinking that to, would be less play when assembled, your right about the stator shaft not moving with different selective washers i was just using a stator shaft no pump .... to see the gap , and not thinking about the pump holding the stator in place ... being a rookie ..sorry !!!
i took it all apart , pulled the output shaft and the gear set ...all was in the right places , now bbond was asking about the beast sun shell using a different thrust washer than stock ... the shell i have has a thrust washer on it and there was NO thrust washer on the center support in my trans .. i have the center support thrust washer it came in a washer kit could this be the problem it takes both thrust washers , some one left the center support one out ... this would let the sun shell sit down in the case with out it ... i took a pic like the one you posted it looks like my reverse drum sits lower compared to the sealing rings on the input shaft in your pic...

Don't compare your reverse drum to the sealing rings in my picture as that is an ISS input shaft which has different spacing. Compare it to the lip which hold the pump.
I'm foggy about your center support thrust washer question as all my builds have used the Sonnax sun shell. I don't think there is anything under a stock or Beast sun shell.

i found this ....sonnax has designed shim 77406-10 for use in 350, 350C, 700-R4 and 4L60-E applications. This selective shim installs between the rear reaction carrier support and the case bearing. This shim allows for adjustment to the total and top unit endplay. The total unit endplay (tested by dial indicator on the input shaft) should not exceed .036"(.005" to .036").

are there different pumps ,that set deeper in the the case?? i saw a pic today on here somewhere of two pumps sitting side by side a there was .020 difference .. but i didnt read why ...

i just read this ...The flange that the stator support mounts with should be able to be substantially thicker than the stock one and not negatively affect anything. The factory clearance between the plastic washer that goes on it and the reverse input drum is close to .100 and doesnt need to be. There are actually a few things that you can do to reduce that if you so desire. (topic for another day) what did you guys give up !!!!!!!!!

When you say "test assembly" do you mean the input and reverse drum installed with the pump? How much input shaft and output shaft end play did you have?
Any guesstimate on how much the reverse drum moved?
Where? What is the context?
Is that implying the Reverse drum has .100 of movement? Presumably that is less than the two tabs on the plastic spacer.

What are those things and why don’t you try them?

hi guys ...that wasnt my quote,"There are actually a few things that you can do to reduce that if you so desire.""(topic for another day)" someone else said that .. in the forums ...i didnt even look at who said it ...but anyway yes i put it all together and like i said the reverse drum moved alot over .100 ... so after tryin a 100 things im at .017 input endplay and .020 output endplay.. i did try shims that installs between the rear reaction carrier support and the case bearing and they reduce input endplay . i tried one then tried two to see if it moved the reverse drum closer to the stator plastic thrust but didnt move it much to help i was trying to do , all it did was take all the input endplay out ..so i took all the shims out .. i put in all new thrust bearings .. yea thats what it was meaning .100 movement in the reverse drum ... where that comes from i dont know once i saw that at least i had something to shoot for ...still sounds like alot ... what would you think minimum clearance ??? is it not normal to check reverse drum play ... i now have about .040 , i can go more i have two different plastic thrust washers .. ones .055 ones .065 ...

I have never checked the play of the reverse drum. The last statement you made confused me.

Are you now saying that the reverse drum play is .040 and that you now have thicker washers to make it even tighter?

just wondering if its to tight , i can change plastic washers and get .050 ... one question if this trans was put in manual second it would start out in second is that right ??? i was thinking it should start out in first and shift in to second and then stay in second .... and if it isnt suppose to start in second what would be the likely problem ??? thanks !!

With the shifter in [D2] the PCM commands the transmission, via the shift solenoids, to start in 2nd gear. You cannot "fix" that inside the transmission as it does what the PCM commands. There might be a tuning "fix", but I don't know the details.
