    You're welcome, man. Let us know how it turns out.

    TransGo shift kit install...

    You're welcome...Those aren't Torlon so wouldn't use either set; check balls aren't supposed to be compressible - if they wear sufficiently, they will get stuck in the plate (I've seen that on other transmissions w/those style of check balls)...The Torlon check balls are a mocha-colored brown...

    TransGo shift kit install...

    The plastic check balls are likely torlon and wont wear the check ball seating locations like the steel ones do - good to have them in there. Replace your 2-3 acc piston, if it's plastic, with an aluminum one. If an aluminum one is already installed, check the pin bore for wear. If excessive...

    TransGo shift kit install...

    I know the kit doesn't require removal. I asked because if you had it on the bench you DO NOT NEED to spend any $$$ on a shift kit to achieve the performance you're seeking. You can dual feed the direct clutch internally, recalibrate for shift speed/firmness relative to converter stall, etc via...

    What transmission? Are you going through it or is it still in the vehicle?

    1987 R10: TH400 to 200-4R swap (mostly wiring??)

    The wiring going to your TH400 is for the detent solenoid. The 200-4R takes a lock up converter (converter with a clutch inside of it). You will need to install a TCC internal/external lock up kit to ensure the converter clutch is applied in 4th gear. Painless Performance, B&M and TCI make...

    Corvette servo

    Do the vette servo ($20) and drill the plate .093" if the engine/converter are stock. Run the billet 4th gear servo if you want to do some towing in OD on a level grade. Make sure you set band clearance correctly - see my vid on how to do so:

    Who needs their TH400 rebuilt in Northern Nevada?

    Thanks, man - appreciate the views on YT. Automatic transmissions are marvels of mechanical engineering, IMO. Cheers!

    If you do end up helping someone w/a rebuild and you both run into a problem, let me know - Im in Vegas and built hundreds of those units so can prob assist...

    72 nova turbo 400 to 84 chevy k20 compatible?

    Ah, forgot about those 205s...That said, unless he knows the history of that TH400 in the Nova, I still recommend he rebuild his K20's unit vs trying to swap in a used unit. not a fan of used transmissions in general...

    72 nova turbo 400 to 84 chevy k20 compatible?

    As is? No as the 72 Nova is 2WD while the truck is a 4x4. You need to take the trans apart, install the correct output shaft for a 4WD application then reassemble it - which would be senseless for you to do given you can just rebuild the K20's TH400 of you're going to do all that.

    There's definitely a winning Powerball ticket with your name on it, just waiting to be snatched up:cool: Nice save.

    700R4

    It's an early 1984 unit if it came with a forward drum w/a 27-spline input shaft. I never pay attn to the rest of the characters; for me they're meaningless. The first character (an integer) combined with the presence or absence of a large, upside down "U" shaped cast crease on pass side of the...

    th350 overhaul direct/forward clutch clearance

    Of course I remember - I don't have Alzheimer's, at least not yet lol. Plus excessive clearance in that clutch was not likely the reason (or only reason) they burned up - the cause is likely multi-factoral). Yes, look into the .090 thick steels...If you have an addl two steels at .020" per steel...

    th350 overhaul direct/forward clutch clearance

    I'm generally not a fan of stacking steels on top of each other as you have but I don't think it will hurt anything. There's also .090 thick steels available as well as the thicker backing plates, unless you already have five .090 thick steels installed...If so, that piston was prob machined as...

    th350 overhaul direct/forward clutch clearance

    Direct clutch should have four (4) frictions & four steels, unless you're counting a wavy/cushion steel...Direct clutch clearance should be fine at .025-.030"...Book calls for .015-.095" but I feel anything more than .060" is somewhat excessive if using a 4&4 set up...Your 2-3 shift will be on...

    700R4

    What was wrong with the converter that made it incorrect for the transmission? Was it set up for a 27-spline input shaft instead of a 30-spline? If so, your 700R4 is an early 1984 unit. Late '84 saw the intro of the 30-spline input shaft, "152" drum casting, large-dia stator shaft and new...

    1986 Automatic Transmission Leak

    Replace your pan gasket (DO NOT USE a cork gasket), speedometer cable/housing seals snd rear transmission mount. Check the governor cover seal, replace that also if leaking. Double check the selector shaft seal - replace if leaking.

    Th350 rebuild (lost drive gears)

    What gouge? Shoot a high quality picture of this gouge and post it Why would you think a torn lip seal inside of the forward drum would result in an external leak? Can you post a picture of the rebuild kit that you mentioned above? A link is fine also but a picture makes it a lot quicker for...

    Th350 rebuild (lost drive gears)

    They're not strictly required though if you run across one, you can put it on...They're sold by Transtar for a few dollars apiece, I believe.

    Th350 rebuild (lost drive gears)

    That second pic does appear to show a cut forward piston lip seal. yea, take another picture but even a small laceration is sufficient to cause the damage sustained by that forward clutch. Also check the underside of the forward clutch pressure plate and see if there are no little indexing...

    Th350 rebuild (lost drive gears)

    Yup! Now you need to find out why that clutch pack burned...Otherwise, you may repeat history w/it...The Direct clutch burns frequently but the forward clutch is always on unless you're not in a forward range position so it's not often burnt on failed TH350s...Check the lip sealing surfaces and...

    Th350 rebuild (lost drive gears)

    Maybe it was - you should have four clutch packs on the bench but I only see three so post a picture of the one not already shown and we will go from there. do you have the ATSG Manual for these transmissions? If not, that should be your very next move - DO NOT rebuild any auto trans without...

    Th350 rebuild (lost drive gears)

    Where's the forward clutch pack? Dont see it in any of the pics above - what kind of shape is it in? How are the lip sealing surfaces on the forward clutch piston? Are they hardened, torn, etc? Direct clutch looks smoked but could be the lighting making it look worse than it is. Intermediate...
