2001 Limited 5-Speed Manual Swap

Hello everyone,

I recently made a foolish purchase of a very rotted 1998 5-speed 4runner with 190k. The condition of the T4R is fairly standard for my area (Michigan). At the time, I was convinced I could make it into something I could daily drive/weekend warrior and still have some dignity left at the end of the day. At last, I faced my fears and admitted the amount of work it needed to get to that point was simply not worth it. I have accepted my mistake and its consequences (mostly money), but am determined to make the most of it.

Several weeks later, after joining the forums and the 3rd gen Facebook group, I learned A LOT more about these trucks and what they're worth. One fateful evening on FB Marketplace, a 2001 Limited with 235k was listed for sale near me with a blown auto transmission for $1200 and I convinced my friends we could throw a new transmission into it and flip it for a quick buck. After reading other 5-speed swap threads, I decided the swap would solve most of my problems as follows...

1. I made a mistake purchasing the 1998, but I could salvage all things necessary for the swap, then part out the rest to make some of my money back.

2. I did not have to search for a new auto trans for the 2001, replace it, list it, and hope we make enough money back for my work to be worth it.

3. The 2001 has very limited rust and is very clean for my area and has no visible rust, the rust that can't be seen can be addressed.

4. I run a small mobile auto detailing business and needed a vehicle to haul my tools + look presentable at a client's home. My current daily driver (2008 Honda Civic 5-spd Coupe) has almost no clear coat on the roof/hood/trunk - NOT presentable and limited storage space.

5. As I am half-way through the swap while typing this, I have learned A TON. I had very limited mechanical experience before attempting this swap - this is something, I think, anyone can do with enough time and determination! Prior experience only included small regular maintenance items. I am doing all work without a car lift, only jacks, jack stands, a driveway, and a piece of cardboard to lie on.

Enough backstory for now... here are some photos of the rust damage on the 1998. More pictures to come.

I'm tuning into this too... rust! Broken bolts! Swapping parts! What could go wrong!?:cheers::pizza::snacker:

Good luck with the build!

People said removing the front driveshaft or reaching the top trans bolts were the hardest part of the job... but these desert dwellers didn't have to deal with the crossmember bolts being completely "rust welded" together. I could full arm swing a 5lb. sledge until my arm fell off and those things wouldnt budge. Wish I could post the video easily lol,

This Swing Arm had already rusted off and was "professionally repaired" by a shop - commissioned by PO.

Brand new cat back exhaust though! Definitely coming with me when I part it out.

A 5-speed swap is still on my "dream list" to do if I ever get bored and have loads of time on my hands, ha. Looking forward to your future success!
 
Thanks man. Yes, they are, so wiring should be very simple.


I think you’re in for a treat with the wiring.

The 01 is a DBW system; so unless you’re going to swap it all over from the donor, it’s going to be a PITA.

Just my .01¢.

You’re going to have to use a manual Tacoma ecu that plugs into your current engine wiring harness, none of the wiring from the 98 will be compatible unless you plan to swap over all the wiring like the body and dash harness. Trust me you don’t want to try and remove the body and dash harness, it will be a nightmare

Thank you for this response, Randy! I did some more investigating and learned that the only harnesses and ECU's that will work for the 01-02 4runners come from 03-04 Tacomas due to the drive by wire as was mentioned (link to thread - 2001 2002 Manual Swap).

HOWEVER, the truck will run perfectly fine with the auto harness + ECU, although you will have a CEL. This is totally fine with me and I can take my time searching for those parts if it starts to bother me. This is especially good news since I can keep the harness + ECU in my '98 and possibly use it as a shit n' git trail bomb rig, if I manage to source a cheap r150f in my area.

Thanks for the response man. It encouraged me to do a little more digging. See my response to Randy. Cheers!
 
Trans and Transfer case are out! I was 2 clips away from having the entire engine harness out from under the hood until I learned I wont be needing it. I will have to reassemble everything I removed to get at the harness, but that's okay with me. Hopefully, I can salvage a trans to get the 1998 driving. Would be a greater winter beater.

For some reason, I only had one trans bolt on the very top to the left of the shifter. I believe the transmission has been removed at some point because there are some blue marks on it like it came from a scrapyard? Also, I dont know what the clutch should look like after 190k miles, but it looks almost identical in wear to the brand new one. Maybe the PO replaced it? Also, the trans fill plug had a ton of silicone around it. Not sure why, but thankfully I saw no cracks when I picked it all off. Very suspicious...

I snapped a photo of me removing the top trans bolt for reference. Using a 3/8 Universal joint and a 10"(?) extension, I was able to angle my ratchet from the middle of the trans up towards the bolt. I could not reach the bolt simply straight on over the top of the trans. If I remember correctly, I did not have enough room to use 1/2 extensions/sockets.

I decided to go with the upgraded Marlin Crawler 1200lb. Clutch Kit. It seemed like the perfect compromise between performance and not being a hassle to drive on the road. The kit is essentially OEM replacement clutch disc, pilot and release bearing, but with an upgraded pressure plate. OEM clutch replacement from AISIN costs $231 on RockAuto at this time and the kit cost me $360, so essentially an $130 upgrade.

Also pictured is the Haynes Manual I figured I should just have, rear main seal + gasket from Fel-Pro, and transfer case seals from Timken.

Also picked up a Beck Arnley valve cover gasket with spark plug seals. I'll need to see if my 2001 has the half moon seals. The guy at the store I called was absolutely convinced that some 5vz's came with them and some didnt? I dont know much about this so...

Old clutch and pressure plate, doesnt seem too worn out... I'll be reusing the clutch fork.

Finally, I purchased a new trans mount from Westar EM5908 (#1237162110), which specifically says it is for 4wd, manual trans on RockAuto. I'll be honest though, this thing does not look like it will work... it seems like the mounts are long enough, but not angled correctly.

Pictures of the 2001 4runner are coming shortly!
 
I’m glad you decided to search for the Tacoma ecu instead of trying to swap all the 98 stuff over, while it’s technically possible, having just removed a dash and body harness I certainly wouldn’t want to attempt it on a vehicle that wasn’t just being stripped for parts. To put it into perspective I had to depin the entire engine compartment fuse box to keep the harness intact

I would also recommend you get an oem rear main seal from the dealer or one of the online sources, I don’t think it was super expensive but being that it’s such a pain in the ass seal to replace I wouldn’t want to take any chances with aftermarket. I’d say get oem valve cover seals but they aren’t too hard to replace and I have aftermarket ones on mine that work fine

YIKES. Yeah, I would probly abandon the entire project if I had to do that. When I removed my gauge cluster, I saw that enormous bundle of wires back there and started sweating bullets wondering if I would have to pull all that out.

All 5vz engines have half moon seals. Parts store guys are only as good as the computer's they are using.
