Just bought an 04 Tacoma PreRunner TRD SR5 2wd AT V6....whew. I have no idea if I broke that down correctly in Toyota terms...lol. Paid a little much for it ($14,700) with 99,500, but I realize these trucks hold value better than any other out there and this thing was CLEAN and well maintained. Being new to the Tacoma I've came across a few things that have me scratching my head a bit. Hoping you guys might be able to help me understand what I have.
- My auto transmission seems to shift a bit rough at times. I don't notice it all the time and mainly notice it when I'm coming to a stop. If I ease into the stop it seems to occur less or not at all. It's when I come to a quicker stop that the tranny seems to be trying to catch up to downshift. It's nothing to make me cringe, however I just want to know that it's a 'Toyota thing' and to disregard. Haven't noticed any other odd feeling transmission related issues except a little rougher shift when I punch the gas.
- This leads me into my next question. When do I turn off the OD (overdrive)? I've read that anything under 45mph in city driving should be OD OFF for better fuel economy and engine braking. Looking for some suggestions.
- Leading into another question...ECT (electronically controlled transmission). I've heard this is the "turbo button"...lol. I've read enough to know that this cranks the RPMs higher for quicker acceleration and that the system is designed to learn my driving habits, but do people actually use this feature full time? Seems good for freeway on-ramp and some extra punch when driving off road trails or passing vehicles on the freeway. Not so good on fuel economy obviously. Can I use this in conjunction with my OD or is this a no-no?
- Rear locking diff? Engage under 5mph? Obviously used for getting out of mud etc, but do you suggest to lock up the rear diff every time I go off road? How fast can you go with the rear diff locked? Do you have to disengage under 5mph too?
