I just bought two 2000 4runners, one is wrecked in the front end but has a good 3.4 and 5spd transmission the other is a 2000 sr5 auto with rear locker. according to the previous owner of the auto, the transmission is bad though it does drive. i need to investigate weather the auto is actually bad or if its something silly like a cv or universal.

If the auto ends up being bad i want to swap in the stick from the other truck. I have done some searching but was curious if there were any good threads out there from people that have already done this?
Things i would like to know:

is this a bolt on affair? if not what has to be moddified/welded/cut/bent?

can i get away with just swapping the engine harness and ecm or do i have to do the truck main harness as well? any tricks to run the auto harness with manual ecm?

anything i am missing?

side note, what kind of oem spec clutch kits do people like for these 4runners?

thanks very much for the help.

As you have all the parts in a complete vehicle .

The putting the holes in for the clutch Master Cylinder opening the hole in the floor for the shifters about the only work.

you will have some work in the harness area .

The Auto ECM can be repined to work with the manual transmission who knows since you have both ECM`s and harnesses which would be easier.

you have the drive shafts to change around.

Clutch quite a few to choose from I run a LUK on one a Aisin on the other people do say Good things about Marlin Crawlers clutch

are there write ups on these modifications?
driveshafts are different lengths i am assuming due to the auto trans being longer?
one thing that i just thought of, are there different gears in any of these trucks?

I think in very general terms, most non-locked 3rd gen 4Runners will have 4.10 gears, and most locker equipped will have 4.30. Which means you'd need to swap the front diff as well. In vague theory the door frame sticker lets you know what diff type and ratio you have, but in reality I think you just need to check it manually.

22REFORME

thanks i'll check that out

i can't seem to find a refference for checking the door sticker, but from reading it would seem that i have 4.30 due to having the rear locker. the auto's transfer case is not usable with the 5spd trans? i REALLY dont want to swap fron diffs...
heres my door tag:




progress report, transmission is ready to drop.

The door stickers seem to be a bit hazy, I really think you're best served just spending some time doing an actual test on the diff.

We're in the middle of a locker swap onto my wife's '96 manual 4Runner, using a locker axle from an automatic. Her original ratio was 4.10, the automatic locker axle was 4.30. We found the rear axle first on CL, then had to look around for a matching 4.30 front diff. And yes, the front diff is a PITA. It sort of mildly looks as though it might be fairly easy, but it's tucked rather snugly between the engine and crossmember, and the steering rack and sway bar gets in the way as well.

I have a '99 manual locker (Highlander) - I'm not entirely sure what ratio I have, I've never checked.

22REFORME

i am confused... i have the rear locker and the matching front diff already, if i am just swapping the transmission and tcase why do i need to swap the front diff?

Jomoka

Sorry, reading comprehension failure on my part. I lost track of which parts were going where. I thought you were swapping a locker rear axle from the wrecked one to the good one.

22REFORME

whew

which transfer case should i use or can i only use one?

just ordered an exedy 16087 clutch kit

stripped the donor truck yesterday. if anyone needs parts speak now ...



ordered a new flywheel that way i can resurface this one and have a spare.

How's the interior? I just need some oak trim.

Jomoka

I have seen the occasional thread here and there were people pondered putting the AWD transfer case onto a manual trans, but I don't recall seeing where anyone actually did it.

AWD would be a nice option for the occasional trip on pavement where it is half-snow covered.

Its not great... also no oak. Check the parting out section of the classifieds
