There's lots of contradicting info out here, even in Transgo's shift kits.
I'm a little slow. This all started years ago, around 2000 when I bought an 87 S10 with a stock 350, Holley 670 Projection, ......
One of the 1st things I did was install an Art Carr kit in it, which I'm undoing, attached file.
In about 2002 I built a 383, which made 310 hp @ 5,300 - 371 ft-lbs @ 3,200 at the rear wheels on the chassis dyno, and started buying parts to rebuild the 87 Aux VB 700r4.
Back then I bought a bunch of parts from Makco, PAC, Bowtie Overdrives, Sonnax, .......
ALTO HP Master Kit, 700-R4 w/ Red Eagle Friction & Kolene Steels
Torque Drive products input drum and reaction shell
5 pinion planets, front appears to be GM, rear is defiantly aftermarket
Superior servos, Hydraulic Lock-Up Package (Superior K017 ), Shift Point Package (Superior K018 )
Just about every Sonnax part that was available
Kevlar wide band
I also bought a cheap Dacco HD-7730 2300-2500 Stall converter back then, which I just installed last spring. Just as I was starting to enjoy it something happen. I'm guessing the converter clutch fell apart. It quit locking up and then I lost all but 1st and it was slipping.
After I got this tore down, I noticed NEW parts where available
So, I bought them, lots of shopping around, eBay, amazon, rockauto, ........ ;
Sonnax 2nd Gear Super Hold Servo Kit, 4th Gear Super Hold Dual Servo Kit, 2.84 Ratio Input Carrier Kit, Billet Forward Clutch Piston (they say doesn't work with their Smart-Tech Input Housing), Smart-Tech Input Housing Kit with Heavy Duty Input Shaft, SmartShell® Heavy Duty Reaction Shell Kit, both L-K & M-K Accumulator Valve Train Kits, Throttle Valve Plunger Valve Kit 77966-94MK
Lots of new ACDelco parts, 5 pinion rear planet 24228763, Overrun Clutch Spring 24206085, Internal Reaction Gear Support 24225931, Steel Low and Reverse Clutch Plate Kit 8687996, ...... reverse input turbulator steels (the Alto Kolene turbulators are NLA), 24241477 Sprag Assembly, 24221190 Shell Kit, 3rd accumulator check 8634400
Alto 057757DX G3 3-4 Clutch PowerPack, 057758 Reverse Input Drum Saver, wide carbon band
Superior 3-4 Clutch Rapid Relief Valve (Superior K070 )
200/325/325-4L Direct drum front bushing, thanks Crosley
350 pump bearing, ACDelco 9436851
Both Transgo kits, 700-2&3, SK 700
Both Superior kits, 700-R4 Kit (Superior K700-R4 ), TransAction Kit (Fairbanks 70015 )
Adapt-a-case center support, that was fun. Being a Tool and Die Maker, I was not happy with their work, so I machined the new center support that came in the ACDelco 8687996 kit.
Teckpak Reverse Piston Capsule
Molded piston kit
A bunch of other Kolene 3-4 steels trying to get the Alto Red Eagle kit to work, which I later read was pointless to use Red Eagles in my street truck.
Transgo 700 PKH pump rings, 7-4-V 3-4 shift valve
just about every 2nd/4th inner and outer accumulator spring I could find
Other parts I've forgotten to list
It's basically together, clearances set to ATSG specs except for the 3-4 where I used the Alto G3 3-4 Clutch PowerPack, shimmed the band anchor pin to 0.015" of the case, and I'm debating on what to do with body. Because of the Art Carr kit, I also bought Transgo's separator plate because I'm sure some holes are TOO BIG.
After some reading, thanks to Dana, I ordered the newer Viton output shaft seal, stock steels for the forward and overrun and Borg Warner clutches for the forward, overrun, reverse, and low/reverse clutches.
More reading, I need to drill out the Teckpak Reverse Piston Capsule, bought a full Alto HEG friction kit, Transgo 7-300, a ACDelco 8648959 .297 low/reverse/intermediate boost valve (because Transgo's machining is too sloppy), Transgo SK700-JR, Ratio Tek RT-700R4-HD.
Debating on pulling this 85 700 pan off to see if it has any VB pieces I can steal, perhaps an "A" accumulator valve, something tell me it won't have one being a Camaro/Firebird tail shaft housing, MTV up valve spring.
Also debating installing the Transgo 7-CS kit, perhaps 1/2 the springs, even though I'm using the boost springs in the Sonnax input drum and my current cam/combo starts falling off @ 5300, removing the Superior 3-4 Clutch Rapid Relief Valve that I've already installed.
Don't really want to go drilling holes in the VB or have full manual. So, that leaves me with the Transgo Sr kit, Fairbanks, and Superior kits.
Which, the more reading I do, I've wasted more money on springs that I do not want to use.
3-2 control valve, Transgo spring is too long, too stiff, making 3-2 kickdown near impossible?
MTV up valve, Art Carr had me remove, leave it out, Transgo spring, or find a stock one?
MTV down valve, Superior's is a lot stiffer
B accumulator valve, replace with Sonnax valve, Transgo spring?
Line Bias valve, block, Transgo spring?
Had to remove about 1/8" off the Sonnax servo pin to get me close to the min 0.075" spec, did that on the cnc lathe and turned a 5mm radius.
I have a custom lockup, N2O, thrust bearing, converter ordered, 3500 iirc, should be on the build bench in about 2 weeks.
any advice as to feed/release holes, clutch packs, clearances, blocking or inverting 3-4 accumulator, forward acc spring, 2nd acc spring, inner acc springs, to use or not to use the Sonnax Servo Release Check Valve Kit (77701-076), pinless pistons .....
The orificed cup plug Art Carr had me install in the 2nd accumulator is coming out.
The 85 700 may become a backup with all these extra spare parts I have.
I've made a few posts in other forums, hopping someone experienced would pop in with some advice
