I don't think I need two front recovery points. Just one big one in the middle should be fine.





These are intended for shipping purposes, using a snatch strap on em will damage the surrounding structure, a single large recovery point should do fine though multiple will give you an out in case one is inaccessible or in a bad line of pulling.
IMO on the subframe, maaaybe the front bumper beam.

Uh yeah for pick n pulls, the one in richmond has some older/moldy cars, I'm generally not a fan as they're pretty haggard and cut up by the time I came along.
The one out in Fairfield was my goto for a few years. They're super reasonable for a p-n-p and if you hulk a ton of parts to the counter, they'll cut you a break. Like when I bought an entire f-series wiring harness, a bench seat, and some other weird poo poo.

There's a new one in American Canyon that I've no experience with.

Probably rtv of some flavor. Get a little seal puller and you can probably put the new one in with the correct sized "big rear end socket."

This or take it to the plumbing aisle of a hardware store and find a suitable piece of pvc/*etc plumbing to drive the seal in.

*I realize that in 2021 a pvc cap probably costs about the same as the genuine Toyota driver.


E: don't pull the metal bracket. Pop the old seal out with however much force you feel appropriate.

Oh poo poo, I just had an intriguing/alarming idea!

You know how some modern cars can modulate the brakes to do fake-limited slip with an open diff? Several times when I've been stuck, something like that would have easily gotten me free. Usually this is when the van is teetering on a diagonal, e.g. all the weight on the front-left and rear-right tires, so the front-right tire just spins. If I could brake just that spinning wheel, I could put power down to the front-left tire that has all the traction.

So, what can I do with line locks? The parts seem cheap enough to experiment with. OTOH, brakes are important and maybe I shouldn't gently caress with them. Hmmm.

Entirely possible. Rover implemented this in 1999.
A long time ago when I gave a gently caress about Rovers I built a retrofit to install the '99+ units into the earlier rovers. It worked, and worked far better than it has any right to.
There's some trickery involved and you need to know how the ABS module works. There's typically two circuits operated by solenoids, apply, and release. Each wheel will have one, sometimes so will both master circuits.
What you want to do is override the apply solenoids without overheating the respective brake. iirc Rover would pwm that specific wheel for ~60 seconds with a ~90 second lockout to avoid melting the brake down. Add some safety features to your project by limiting its operating speeds to sub 30mph, switch lockouts, etc. Rover ran this system up to 65mph.

Worth seeing if tundras/sequoias/landcruisers get similar hardware and try to graft their parts into the Sienna.

I would definitely buy a winch, mount it on a receiver mount, and install receivers on both ends of the van with quick connect cables, if I didn't want one permanently mounted.

Seconding this.

Bumper vs not?
Ziptie the stocker on for now. Trim some of the lower edge off.
Go with the prerunner idea, the shop that built your skidplate might be up for it.
Mostly tube with plate mounts to the unibody and a sheet metal skid shouldn't be 100lb.

I've run lovely cheap amazon light bars and a pile of various products from baja designs.
its all in what you want the pattern to be.

Work light | flood | throw light everywhere and anywhere: Do the cheap ones
Want to haul some rear end and see where you are going? BD or bust.
Devils advocate: while you're doing lighting, throw one out back as a camp light. Really makes a difference. I ran a couple like that on rovers and it owned.


bumpers and radiators: my f350's bumper is about midway across the rad too but it doesn't have a prerunner bumper on it, just a massive old warn unit.

Yes, this is useful to me. I am primarily concerned about terrain within 2-5 car lengths of me. On anything technical I end up spending all my time puttering around in 1st gear at 5-10 mph.

Now that I think about it, there was one time I drove up Hogsback Rd near Red Bluff, at night and in the rain. There were a couple times I had to get out in the rain with a flashlight to check out an obstacle, that kinda sucked (not really, was pretty fun tbh).

Yea, BD got you covered! (their warranty is top drat notch too)

Here's a mod to my bike I designed and 3d printed utilizing their spot(highbeam) and driving(lowbeam) patterns. The forced cooling came as a part of the second revision to avoid thermal throttling the modules.

Had a little freetime to help with the project.
Using StormDrain's photoshop.



I added a tiedown point that uses the original towhook to help avoid twisting the bumper during winching. there's two extra tubes that reinforce the receiver hitch.
There's also a lower spar that protects the condensor/radiator/lower cradle. Bent the skid plate to go under that as first line protection for that spar.
The support bars that cover the washer bottle can be thrown either at the lower tie in if the welder can pull that off, if not, its fine to move it just above it.

No, the ideal mounting place for the receiver is inline with the bumper attachment points otherwise a torque gets placed on the bumper and its mounts. Specifically was building on Stormdrains sketches. I'd run a tube across the middle of the main mounting points below the main hoop to put a receiver on.

Seconding everyone else. 4 speeds aren't that hard to rebuild.
While you're in there throw new seals at every piston. Be gentle with the apply pistons at the end of the clutch stack. The seals there easy to pinch. The nylon circlips that ride on the shafts should also be replaced. Don't put those into service dry. Dunk in atf, install, send.

Soaking the clutches in atf for half an hour or so is plenty. Some just dunk em and send it. I tend to soak em overnight but I'm hell on equipment.
Look for heat damage on the hard parts. Anything suspect should be replaced.

Go to the surplus store and buy a handful of old dentists picks. Be loving careful because they'll gash your fingers up. (One of my former bosses got stitches because he borrowed one of my picks but didn't listen)
Then buy some *good* circlip and snapring pliers. Some of them are bigger than you'd think.
Some cheap disposable small straight edge screwdrivers are good for bending into useful tools for walking out apply piston snap rings.
Anything else an be made on the spot with creativity and a slight amount of annoyance.

Keep an extremely clean work area. Cleaner than your kitchen clean. Lay things out in the order you removed. Don't gently caress with that order. It helps to have a workbench and a jig for the transmission made out of literally whatever so that you hoist parts out of the transmission with the bellhousing side facing straight up.


You got this.

You shouldn't need a press to break down clutches other than to maybe hold the return springs.
I don't really see any gotchas in the teardown section of the manual.

Kits come with gaskets, steels, seals, filters, and frictions. It's on you to get the torque converter and ancillaries like the pump.

Going to point out the torque converter also has a clutch within it that is also now contaminated with motor oil.

e: so do I have to literally break it down into its component pieces and degrease every part?

If you want it to work and work for longer than 6 months when you're done with replacing the soft parts, Yes.

Otherwise the debris left in corners and pocket is ripe for getting sent right through your homebrew reman. At minimum earning you an opportunity to drop the valvebody again and backflush solenoid screens, at maximum, partially jamming a servo and leaving a clutch engaged when it shouldn't be, always wrecking a host of hard parts.

Same thing happens when a neglected transmission gets its first flush/service in ages. It dislodges sludge and other garbage.

Welcome to the dark arts that is automatic transmission overhauls.
