Keep it going! Good stuff.
Its funny this thread came up, i did a 48re this sunday that was in almost as bad condition. 90% of the band was down to the steel . Amazing how much clutch material can find its way into everything. Auto's are like body work. Half the work is prep and cleaning.
A valvebody upgrade walkthrough would be awesome. Very intimidating when you first tackle one.

Big blue, what kind of power will this 48 hold the way you are building it?

With a valvebody you want a manual in front of you the first time. I laid mine out on shop towels and wrote the corresponding number for each part from the ATSG next to them
Seriously, I'm still finding clutch material in odd places and my trans was a lot cleaner inside

Next install new seals on the billet input shaft. The Transgo shift kit provides new upgraded scarf-cut teflon seals.
Install the upgraded green teflon seal, then install (2) new seals provided in the rebuild kit.
Install the forward drum on the input shaft and place it shaft down to work on the forward (rearmost) clutch pack.
Replace seals on the piston:
Use lip wizard (supplied in rebuild kit) to ease piston with seals installed into bottom of input shaft hub.
Pictured below is the stock 48re belleville spring which is a weaker design than the 47rh & 47re. This spring is fine for stock or mildly upgraded pressure. For safe capacity in the 200 psi line pressure range, it's best to upgrade this spring with a stock belleville spring from an older model.
Upgraded spring on-top, stock 48re spring on bottom.
This isn't a 100% direct swap since the piston to forward drum distance is not identical between the older and newer transmission. The old style belleville spring is loose when swapped in-place of the stock 48re spring. A simple shim can be added, a custom billet piston, or "other" custom tricks can be used, sticking with the stock 48re spring is fine for 90% of tranny builds out there. It's the full-blown race trucks utilizing 195+ psi line pressure that need an upgraded spring and 250+psi that need a doubled up or billet spring because the old style fails in the 250 psi range.
Install cushion spacer and waved snap ring:
Next install stepped pressure plate:
Install stock count (4) frictions and (3) steels topped off with the stock thick reaction plate, remember to soak the frictions for a minute or two to get them wet with trans fluid:
Check clearance between the snap ring and top reaction plate, I like to see .020" minimum, if sticking with stock spring and clutch setup, the clearance will be perfect, no need to mess with thicker or thinner snap rings, steels, frictions, etc. This clutch is applied in all forward gears so clearance is only an issue when driving in reverse and the clutch pack is forced to slip.

Next comes the direct drum also known as the 3rd gear drum, start by compressing the release springs to remove the snap ring in preparation for piston removal.
Stock 48re utilizes (9) return springs, I've found (9) to be adequate although some builders do install all (15) return springs.
Install new bushing:
Picture of wear marks, add a hole between the wear marks to aid in direct clutch application. I like to go .125" on this added feed hole opposite the factory feed slot.
Replace large outer seal on the piston and smaller inner seal on the drum itself:
There are aftermarket pistons available for this drum, however, the stock piston provides adequate space for clutch pack I like to run so I don't upgrade the piston. When the day arrives that (6) clutches won't hold, it's probably best to upgrade the whole drum assembly for a billet steel unit.
Install piston, be sure to pre-lube the seals with ATF.
The stock 48re clutches and steels measure roughly .086", utilizing a stepped reaction plate, there was enough room to run (4) .086" frictions and (2) .064" frictions for a grand total of (6) clutches and (6) steels. The rebuild kit came with (5) .086" frictions and steels so I supplemented the kit with (2) .064" high energy frictions and (2) .069" steels.
Then the pack is topped off with the custom stepped reaction plate and selectable thickness snap ring. The stock setup used a waved snap ring to cushion the application of 3rd gear, for firmer application, a flat snap ring can be used.
Then check clearance, it's good to end up with .010" minimum per friction so .060" minimum for this build.
This one ended up at .072"

HP capacity is really more related to the amount of torque put through the tranny. Big single turbos produce less torque that quick spooling twins so trucks with quick spooling twins need more line pressure to prevent clutch slippage.
This tranny is being built for the customer's future upgrade plans for 700 ish HP or up to 1500 ft lbs of torque at the tire. With simple line pressure adjustments, this tranny is smooth and tame for the lower powered daily driver and aggressive and firm when pressure is cranked up to 200 psi for bigger HP and TQ capacity.

A couple of Issues while doing my Valve Body
I have a couple of questions about my rebuild.
While at work my workbench "got messed with"
So I need so help in solving the puzzle of what order a couple of valves go in.
this first and last pic shows that this is as far as the steel plug?? will go in. and the order I put them in, I know this one came out and back in in the correct order.
does the second, third, and fourth pic look correct?
Lastly the Lock up valve, I cant figure out how it goes in with that plug.. is it plug valve spring?, does that plug belong with this valve..
thanks in advance

Test Drive after Transgo and some Sonnax Parts
Question - HELP
SO I just installed my trans-go kit, Sonnax billet accumulator and 2nd gear super hold servo kit.
My Trans-Go kit did not come with the green TV Spring..
I turned the PR Valve spring adjuster in 2 turns
Drilled the the separator plate 2 to 3 (A & B) holes to .110 and 1 to 2 hole to .088
Drilled the Lock up pressure plate to .075
Installed Borg Warner solenoid, and new transducer
Trans as far as I know is stock besides what I have just done.
I followed Big Blues instructions for the most part, did not drill as large as its easier to drill bigger than to fill a hole back in..lol
So here is my issues I would like to correct;
1st to 2nd gear shift happens very quickly, like before half way through a left turn, I would like to see that wait a bit.
The shift is not as firm as I would like ether.
Second Issue at half throttle or more the 3 to 4 shift hangs a bit then shifts and some times it comes off of 3rd then shifts to 4th.
Lock up feels nice and firm.
Should I bump the line pressure up another turn to firm up the shifts?

Someone asked me to post the BW part # for the 10 rivet Borg Warner solid flex band.

I disconnected my TV cable, then ziptied the lever, and kept tightening it a little each day until I liked how the 1st to 2nd gear shift was. Then I dropped the pan and adjusted the tv screw to hold the lever there (as a minimum, obviously). Then hooked everything back up and I LOVE the difference. Now it shifts just after the turbo starts to light, so when it shifts it is still just starting to light and it doesn't fall on it's face and smoke. My truck is actually 100% smoke free if I am DDing it, and not getting crazy which I love. And towing is much much better from a stop.
2-3 doesn't change much, but I'm moving fast enough by that point that it could be increased another 100rpm to be perfect, but it's good.
3-OD is based on your TPS and your speed, so is TCLockUp. I have 37's and the stock gear/tone ring thing in my tcase, so my speedo is pretty far off. That makes it shift early. I've been saying I'll change it for years.

I also loosened my TPS and rotated it to make the PCM think I am pushing on the throttle a little more.

Got a 47re torn down today. I've only found 2 issues. Overdrive piston seal was blown out and overdrive clutches are burnt to hell. This is going in a stock grandpa truck. Should I upgrade either of the servos or bands?
I'm going to do a shift kit, converter, seals and bearings for sure.

I believe its used for reducing wear because the Teflon retains a thin film of oil
