I have a '96 Taco with 5 speed and a '02 Double cab with Automatic. I want to switch the two tranny's and put the 5 speed in the '02 and the auto in the '96. Long story, but I have to do it. I've done a lot of reading and found a few good write-ups from people who's done the 5 speed swap (like junglecode). Two Questions remain unanswered:
1. According to offroadsolutions.com, the crankshaft in select model years is not machined to accept a pilot bearing/bushing. Does anyone know which years, i.e. will I be okay with the '02?
2. I'm not too concerned about putting the 5 speed into the '02, but what bothers me is putting the auto into the '96. My understanding is that the auto is being controlled by the ECU. So, will I be able to simply get an ECU out of an early (1st gen) Taco or 4Runner with an auto and switch the ECU's? Any advice? Thanks

Winch,

For the ECU question you would need to get an ECU that will work with the trannie and engine. What trannie are we talking about in the 02? was that trannie available on the 96?

The tranny in the '02 is an A340F, and this tranny was also available on '96 models. Problem is, if I'm not mistaken, that the ECU on the manuals only have two rows of pins, and on the auto's they have four. So, the wiring harness won't fit. But, I'm not completely sure of this, which is why I ask. Thanks

From what I've heard, it really isn't worth it. Too much time and money. You'd probably be better off selling your truck and buying another with the 5 speed. I know it doesn't sound fun, but that would be MUCH easier and cheaper.

well, if you have your heart set on a 5 speed double cab, unless it's an '05, it ain't gonna happen unless you swap it...

I'm really interested to hear your comments about why it ain't gonna happen. Not that I disagree, but it sounds to me like it can happen. These guys have done it: http://www.junglecode.com/toyota/tacoma/transmission/ and common sense tells me it can be done, and the people who own Supras (7M-GTE) have done it too.

I do however agree now, after more research that the auto swap into the manual ai't woth it. There is an outfit, however that sells a automatic transmission controller (forget the site, but this is what I searched for) for $700 that will do what the ECU does. But that's not worth it to me, I'm more interested in getting the 5 speed into the double cab.

what kyle is saying is that dcabs until 05 werent avaialble with a 5 speed, and that if it was to happen in anything otehr than an 05, it would have to be swapped in....

he was saying tha in reply to 0ly884 's comment on jsut sell your truck and buy one with a 5 speed....

Okay so now you have the tranny question answered. What about the engine. what I am pointing to here is swapping out the harness as well. to get the 96 to auto will be easier than getting the 02 to manual. Was there any toyota 4wd manual avail with the engine and trannie you want to use...if so that is the harness that you want to start looking for.....I can help with the research if you provide me the engine and trannie models for both the 96 and the 02. On this harness swapping trick have to be careful Toyota loves to switch from square to round connectors between years...that will add some fun to the trick also.

no dcab had a 5 speed before 05

What sucks is that when I got my ext. cab in 01 the only thing that kept me from getting a double cab, besides no passenger airbag cutoff switch, was the fact that they only came in an automatic. Hilux trucks overseas in double cab configuration could be had with a 5 speed and a turbo diesel!!!

Initially, I wanted to simply swap the two tranny's, because I already have them and evryting else that goes with them, like clutch pedal, etc. Based on some of the feedback, I've been getting on this project, I'm now thinking that I should buy a used 5 speed for the '02, and sell the A340F auto that comes off the '02, and I should still break even, and then I don't have to mess with the '96 at all.

So, I can get an R151F 5 speed out of a 1987 Pick-up turbo, with the 23 spline T-case which will make my dual T-case setup a lot easier.

So, the info you're asking is:
Engine on the '02: 3.4L V6 (5VZ-FE)
Tranny to be used: R151F
Tranny on it now: A340F (30-40LE)
Ecu harness has 3 rows of pins and 4 plugs side by side

Like I said, I might not bother with converting the 5 speed to an auto on the '96 anymore, but here is that info:
Engine: the same
Tranny to be used: A340F
Tranny in it now: R150F
ECU harnass has 2 rows of pins with 4 plugs

So, do you mean I should look for the harness off of a 2002 Tacoma Xtracab with 5 speed?

Thanks

My thinking is that if you can swap a 3.4L engine into a manual transmissioned truck, you should also be able to swap a manual transmission into a 3.4 Litred truck, because the only variable really is the ECU and the wiring.

I see that ORS make custom wiring harnesses for the engine swap, so Mike should also be able to do a custom harness for a tranny swap, or maybe I can figure something out from all the diagrams I have.

My questions are:
Does anyone know which ECU I should use?
The auto tranny on the '02 has, as far as I can tell, 2 vehicle speed sensors, ATF temp sensor, shift solenoids and and shift position switches. What do I do with these, as the ECU from a manual tranny'd truck, probably wouldn't have pins for these?
Do I keep the stock '02 ECU and try and fool it with resistors or jumpers?
Do I even have to bother at all, i.e. what's the worst thing that can happen if I do nothing about these? A check engine light?

Thanks for any info.
