New transmission on the Tacoma

Anyone think it'll be reasonably feasible to swap the new 6 spd auto from the Tacoma into our trucks? Really wish we had a bit better gearing... :decision:

No. I'd be pretty surprised if you could do the swap economically. Probably easier to do the transmission and engine and all the electronics than trying to make the transmission work with the existing engine.

Physically it's probably a bolt up swap. The A760F is probably the one they'll use. It's already bolted to a GR in the A760H configuration in the IS and GS models.

Would be nice. First through 5th gear ratios are the same across the board, but having an extra overdrive would allow a lower differential ratio. Basically a 6spd and 4.10 gears would add a nice benefit.

The AA80E from the LS would be much nicer. Or the AA81E from the newer GS/IS models. It has a 4.5:1 first gear - much lower than the 5 or 6 speed 1st gear and very low for any automatic. And since the AA81E already has the right bolt pattern on the bell housing, I'd go that route over the Tacoma 6 speed. I don't know that the electronics will be much more or less work either way. Both are likely to be a huge PITA electronically would be my ignorant guess. I really don't know. I think it would be awesome to have that great low 1st gear.

I think a 6 speed manual swap would be worlds easier than this. Someone needs to do a write-up for that!
 
These rigs are still too new for people to start digging in... but I would love to see the Tacoma/FJ 6-speed manual swapped.

I would love a manual swap in my 4Runner. It would take care of my biggest complaints with the vehicle.

I did an Auto to Manual swap in my 90 Nissan 240sx, and it was easy enough. It even had the clutch pedal bracket already welded on the firewall from the factory. It was pretty much just a bolt in affair, and I kept the Auto ECU, and just tricked it to thinking it was in park all the time, so it would start...

I don't think today's electronics would make it very easy for us to do the swap though. I would assume you would need an ECU from a 1GR-FE w/ a MT, and from there, who knows how it would interface with the rest of the vehicle.

I guess since LC Prados do have the option of a 1GR-FE with a MT, it would be possible to get the parts you need by importing a Front Clip, or Half Cut from Japan in the future, I just wounder how you could get it to work.

I've done the swap on a 94 Ford Explorer and it was all pretty much plug and play. Even the clutch switch wiring was in it, just had to remove a resistor and plug the switch in and it was good to go. Since it had a vacuum operated transmission the manual wiring was straight forward as well.

I have yet to look at an FJ or Tacoma to see how the clutch is attached but I would see that being the biggest hurdles since the FJ came with the GR and a manual. I would imagine we'd even be able to program our current ECU for a manual map as long as it played nicely with the other modules in the car.
 
Since the CPU from the 1GR in the FJ the 5speed seems like it could very well be do-able. Maybe the 6 speed MT will be very similar? The H55f is much more desirable for offroading due to the low 1st gear ratio- but I'm not sure how well it mates up to the rest of the 4runner bits. I think the clutch lever should be one of the easiest parts if you have some fabrication experience. Either cut the firewall section out of a truck and graft it in,or just buy an aftermarket kit. It's just a master cylinder with a lever and a pedal. Lots of aftermarket options like this guy:
