Manual swap, how hard? Ecu is the toughest part right?

[johnsoma73]

How hard is the manual swap?
I feel like the mechanical parts would be easy and the ECU would be the toughest. From what I read you have to repin and reorder it? Correct?
Does anyone sell it redone?

I am not positive on the ECU but there is a different ECU for manual vs. auto. You will also need to decide which transfer case to use. Manual 4Runners had a standard J-Shift case. This will also dictate what you need to do with the driveshafts as far as shortening/lengthening. You may also need to relocate the VSC computer and all that so you can fir the clutch pedal in.

I know this isn't much help but, there are definitely some folks on here who have executed this successfully! Hopefully they can chime in for you. Good luck!

Actually, the ECU just plugs in; it's probably the EASIEST part!
Pretty easy swap on an '01.
You need the ECU from an '03/04 manual V6 4WD Tacoma. Plugs right in and works properly.
4 wires from the clutch pedal switches to behind the glovebox to make the clutch start and cruise cancel switches work like they should.
The rear driveline will be a little short, but it will work. Ideally, a 1" spacer should be added. The front driveline will be too long, but it will also work.
The toughest part is drilling the firewall in just the right spots for the master cyl.
The '03/04 Tacoma didn't come with VCS/TRAC, so the new ECU won't support those systems. The VCS/TRAC ECU also controls the ABS- which controls your brake booster and speedo- so you need to keep that ECU. It's located where the new clutch pedal needs to go, and finding a spot to re-home it isn't the easiest task.

It's really like any other manual swap. When I say "pretty easy swap on an '01", I don't want to mislead you. I have no idea of your abilities, knowledge, tools, or workspace. I guess maybe it's not for the "average DIY'er". You definitely need to have access to EWD's, and understand how to interpret them.

Listen to him. And you’ll be good. He and I have done manual swaps. If its a 96-98 then you’ll need to get a manual ecu and repin the harness. Or get a manual harness and swap it. Repin is easy. You need a EWD, beer and time. Pin by pin. End result. No check engine light.

I have a similar question...

Considering swapping the 3.4 from a 98 automatic into a 96 with the 3.4 and 5 speed manual. Both 4x4. Want to swap engines only and keep the 5 speed in the 96. I am assuming use the ECU and wiring harness from the 96 and treat the 98 engine like a long block install?

Any issues I might run into? TIA.

Easy just to swap motor, my 99 5 speed has a motor from a 2000 auto.

Excellent, thank you. I would assume that I also use the flex plate from the 5 speed?

Only auto's have flex plates. So no; don't use that! [emoji6]

ah, I got it backwards! Appreciate the help. Any snafu's to watch for? I would think this should be a pretty straightforward swap.

Flywheel actually, flexplate from auto gets tossed, you just want the stripped down motor from the auto, it'll get all the 5 speed stuff, and you'll want a new clutch, throwout, pilot, machined pressure plate, maybe some new shifter bushings....if you're iffy on the swap, get some help.
Save what you can off the motor you're junking, will be nice if you need them some day, throttle body, coil packs, etc., Also gauge cluster for def sure for the motherboard, and anything else you can think of saving on the skeleton. My wife nags me about all the 3rd gen stuff I'm hoarding.

Not bad to do. ECU is the hardest part. 01/02 is gonna be a fun though.

ECU is plug-n-play on '01/02. Definitely the easiest part of the swap.

Hey all, anyone know what 4 wires!?!? I swapped my 2000 and decided to swap motor harness to the trans....my 4runner won't start because I can't "clutch cancel." I'm not having luck finding which wires to run and where!!

Read this thread -->5-Speed Swap Wiring Diagram

Basically there are two wires that need to be in a closed circuit for it to start. Connect those and you should be good. Read the thread for more details.

Hey, so I’ve got an r150f and a j shift from a 99’ I wanted to swap into my 02’ auto but I didn’t get the ecu for the manual because I had heard I could get around it by bypassing the start neutral safety switch… now I’m stuck wondering what to do with my abs computer so I can put my clutch in. I’d like to keep the trac and abs but I don’t care much for the vsc. Hopefully one of you guys will be able to help me figure out a solution for the wiring. Would it be better if I just got a manual ecu and harness from a 99 or something? I am not a mechanic but through YouTube I’ve figured out how to do the rest of this swap, but electronics confuse and frustrate me

Only '01-'02 have TRAC, previous years only had 3-channel ABS with no other aids (and sometimes no ABS on 4-cylinder models). A '99 ECU is also not compatible with your throttle body and cruise control setup.

Okay, so after some more digging it looked like I could just get rid of the Abs VSC Trac computer and just live without ABS, however when I unplugged the computer my brakes were stiff as a rock.
Is there a way to delete ABS without the pedal becoming stiff?

If not are you familiar with relocating the ABS/VSC/Trac computer? I heard it’s possible to cut off the mounting brackets and tuck it under the drivers side dash to fit the clutch in, but I’m not sure where or how to secure it.

I’d prefer to be rid of the computer but if it’s necessary to run the brakes even without abs then I guess I’ll be finding a new home for it.

Thanks
