Yes the new '05 Taco has a 6sp in all models if you want it. It was only the previous double-cab that you could not get a stick in. I think a new Taco, 6sp manual, double-cab, short bed (maybe even bobbed some) would be a sweet truck!
However, does the TRD still have the rear e-locker? I could not find it online where it said it did, it said it had a limited-slip rear differential, but I did not see the locker. There are about 5 'offroad' packages though so I could be (and hopefully am) mistaken. I keep meaning to go to a dealership and look at a TRD and see if it has the locker switch, guess I could look on Ebay, I'm sure someone is selling one there with good pics...
Edit: Ok nevermind, only 2 on Ebay and no pictures that are worth a crap...so anybody know forsure about the locker?
Edit2: Nevermind again, I just did some research and it's a bit confusing, on some sites it does NOT have a rear locker, only a limited slip rear, but on Toyota's site it does, but ONLY for the TRD Offroad Package #1/2, the TRD Sport Package does not have a locker, only a rear limited slip, I guess the name "offroad" makes sense then, but didn't realize some TRD ones would not have it.
