Shifting Sweet Spot

What is the best spot to shift for my 2.7L? I usually shift around 2500rpm.

I wind out 1st to 3k or 3500 the rest of the gears I shift at 2-2500. It's really clunky if I don't

Sounds right, because you have a distinct advantage over the larger heavier Gen 2's.

I shift at between 2,000 and 2,500.

I did the same with my access cab, first gear was really clunky if I didn't. Can't say anything for a first gen 2.7 manual since the transmissions are different. I bet they are smoother though, the first gen manuals were better than the 2nd gen manuals by a long shot.

Aren't they the same transmission? I took the chopped shift lever off my 17 year old gen 1 and it fit perfectly on my 2012 gen 2.

Nope, they are different according to gearcruncher.

A heavier shift knob helps with smoother shifts also I've noticed. I had an aftermarket one on my 2011 and it helped a lot.

sweet spot for what?

MPG?

Feel?

Drivability in traffic?

Regardless of which it is (which may have varied answers) it should always be at enough RPM to avoid lugging the engine in the next gear. It won't take but once or twice of doing that and you'll know exactly what to avoid.

In terms of driveability, if you had a dyno chart with the torque curve (one around here somewhere?) you'd want to shift at an RPM that did not let the next gear fall out of that curve.

Feel can be improved in a number of ways. Heavier shift knob, synthetic fluid, proper clutch pedal adjustment, etc. A shorter shifter, but one that leaves the original fulcrum point, can actually make shifting harder. You may be changing the distance your hand moves, but the actual 'working' part is moving the same distance as it was, so you'll disadvantaged your leverage. But they do look cool.

MPG? Read some hypermiling sites. And still don't lug the motor, but barely above that threshold.

I have thought about this question for the last few days while driving my 2.7. I would say anywhere between 2,500 and 3,500 depending on what I am doing, with the higher RPM shifts for those times when you are moving out into high-speed traffic. Going beyond 3,500 it's somewhat diminishing returns as far as the added acceleration you get.

Going four to five is somewhat of a special case with this truck as I generally will just hold fourth until I reach cruising speed, whether that's 45 mph or 75 mph. You're only going down from 1:1 to 0.81:1 when you go 4-5 so the rpms don't get super high even at 75 in fourth.

I don't think I've gone over 3K rpm's on purpose, but I've babied all my Toyotas and hope to be well over 300K miles when I'm all done with her.

Me too! It's rare when I go past 3,000 but it does make for pretty rapid acceleration when you need it if you go a little past now and then. I bet the automatic lets it wind out more than most people do with the manual.
