1st gen v6 manual transmission swap

ok guys, i have searched but cannot find anything 1st gen tundra v6 specific to my question so here goes... ill try to keep it as short as possible...

i have a 2004 single cab 3.4 v6 5vzfe 2wd tundra with an automatic transmission. last monday my torque converter started going out, actung funny, got a check engine light and everything, took it to the shop, they confirmed it needs a new torque converter. its not going to be extremely cheap, and also i am not a huge fan of the automatic anyways, so what i also have is a
1996 4runner 3.4 v6 5vzfe 5 SPEED MANUAL transmission truck rusty frame for parts only, im sure you can see where i am going with this.

first, could i just pull the r150 manual trans from the 4runner, and put it in my tundra? id rather have the 5 speed anyways vs putting money into an automatic that i dont love.

what parts exactly would i need? ive read about a few people swapping v8 tundras to 5 speeds, but cant find anyone doing it to a v6 truck, does the dash support have brackets for the clutch pedal, will i need a different ecm? transmission cross member? master cylinder? how hard is this gunna be? i love my truck, just rebuild the front and back suspension and rebuilt the rear end with a locker as well as added larger front brakes and disc brakes in the rear, i just did my timing belt and a custom aluminum radiator, i do not want to sell the truck and buy a manual before anyone suggests that, specifically i am wondering about how involved this 5 speed swap will be and if i will have ecu problems, or problems with the throttle by wire style throttle body that i have on the 2004

 

Completely doable. But not sure it's been done before much on a 1G Tundra.

You'll find much more info regarding this by searching 1st Gen Tacoma forums. I would start there and get a good feel for what the swaps require and it will be very similar for the Tundra.

I've done a 2wd (PreRunner) to 4wd conversion and an auto to manual swap on 2 separate 1st Gen Tacomas. It's actually not super bad if you're mechanically inclined (I'm just a DIYer).

You're on the right track with your list of stuff you'll need from a manual equipped Tundra donor: manual trans 4wd ECM from equivalent production date, clutch and brake pedals, master cylinder, fluid lines, a manual trans flywheel, clutch, throw out, all that jazz, yes a manual trans cross-member, rear driveshaft (also front driveshaft if it's 4x4)... and depending how nice you want to do it, all the interior bits and brackets and boots to seal and pretty up trans tunnel.

 

I haven't done it, so just speculating here. But double check the transmission output shaft compatibility. They are frequently different even within the same model for 2WD vs 4WD.

 

the ecu is what i worry about finding a little bit. is there any possible way to trick my ecu into thinking the auto trans is in neutral or something? not sure i want to get into swapping ecus, as ive heard potentially the harness is different as well

 

output shaft meaning where it hooks to the driveshaft? worst case scenario i have to have a custom drive shaft built right?

 

Yes, where it connects to the driveshaft on a 2WD. Because on a 4WD it connects to a transfer case.

 

Should be do able. The v6 was available factory with a manual trans.

Just a matter of sourcing parts.

 

Yes, automatic and manual transmissions were offered in the V6 model of the Tundra. I guess what I haven't been clear about is to make sure the transmission is the same between 2WD & 4WD. I vaguely remember from my Gen 3 4Runner days that guys would want to convert their 2WD to a 4WD, and if I'm remembering this correctly, they would find that while the basic transmission was the same (A750), the output shaft was different.

 

I believe you're correct. When I owned an 03 manual FGT I looked into the 4WD swap- it required the 4WD transmission, or to use the same 2WD transmission and swap the output shaft.
