The 22RE is lucky to go 200k before needing a head gasket and you'll want to do timing chain, sprockets, guides and other things while in there. I consider it normal maintenance for that motor. I would say that coolant consumption is actually the most common way for the 22RE to let you know it's time for a head gasket. If your motor works good for you otherwise, I would just do the work before it gets worse. A lot of people talk about how reliable the 22RE is. It's very reliable if you consider pulling the motor apart every 200k or less reliable. As long as you are willing to do that before overheating it, it will last pretty much forever.
I believe the engine harness, and definitely the ECU, are different on an auto. Don't think you can go to a manual. I did manual to manual, so the other guys might be able to confirm.

My 3rz came from a prerunner auto. I had to get a manual ECU of the same year on ebay.

Still in infant stages considering the 3RZ swap as well. Other than ECU, and then bellhousing & clutch parts, is there anything else special of using an auto truck?
How hard was it to find a manual ECU for you?
Ebay will be your friend. I just bought 2 MT ECMs for mine.

Nothing special other than ignoring or removing the extra wires in the harness that led to the auto trans. No problem finding the 4X4 manual ECU on Ebay. I also had to source the flywheel and bought new flywheel bolts
Look
Go to Toyota parts deal, look up the ECU according to your donor truck/engine year.
It will show you what ECU part numbers that will work. I installed a 2rz from a 2004 auto, got a 2rz manual ECU, used ORS wiring harness worked great.
To update, I was able to beat all the auto transmission codes for my 3rz swap.
I used
3 470 ohm resistors for the transmission shift solenoids
A 2.2k ohm resistor for the transmission temp sensor
Wired the secondary speed sensor to the factory VSS using the wire coming from the SP2+ side of the ECU.
I’ve had a couple hundred miles on it since fixing the last code (P1700) and it hasn’t come back.

Just a heads up for anyone planning on doing this, the 12101-75090 Oil pan is discontinued as of last year. If anyone has any leads on one, new or used, please let me know!

When installing a solid axle swap kit on your 95-04 Tacoma you will notice that your stock oil pan will interfere with the new solid axle.

I got this kit when I did the 2rz swap into my 2wd pickup
looking around, this part doesn't pull anywhere for a prado.
i only see it as a hilux. which as far as i can tell is the only vehicle that ever had 3rz and torsion bar ifs with right side front diff.
prado went from leafs to coils.

That’s what I found too. It was on Hilux’s with both the 2RZ and the 3RZ.

Hmm…I’m pretty sure that’s the rear sump pan on the T100’s, which I currently have. I was told it wouldn’t work with IFS. Maybe it works with 2WD though, because you’ve clearly gotten it to work?OEM T100 Oil Pan Kit For 3RZ Tacoma With Solid Axle Swap OEM Toyota P/N: 15147-75020 15104-75050 15301-75020 11409-75020 12101-75060

and along these lines 4wd 3rz t100 do not exist.

I was more referring to that oil pan working in swaps, but yes
a 4wd 3rz t100 would (have been) be the right pan for ifs swaps. that's all im saying.
Ya know, I had to check this. You are correct. The 4WD T100 trucks were 3VZE or 5VZFE. Only the 2WD trucks had the 3RZ in the 1994-1998 model years.
i had a friend tell me someone told him the 3rz/ifs pan was early t100. that sent me down the rabbit hole, because afaik 3rz was 2wd only. the parts book confirmed and so did ogbeno.
