Nitro 5.29 Gears "Too Aggressive" for 2016+ Tacoma's? Nope! Perfect.

All of the comments above imply that a good driver can’t tell when the engine is “lugging”, running too low rpm for optimum fuel efficiency, and possibly over-working the torque converter and increasing trans fluid temperature. The good thing about these new Tacoma’s is that it doesn’t take much mechanical sensitivity to want to downshift to 5th or 4th or 3rd. The only comment I agree with is that the 6 speed I paid for is effectively a 4 speed. And, I may sing a different tune if I had an ATF temp readout. But again, coasting downhill at 70 mph in 6th at 1200 rpm does help recover fuel economy lost on the climbs. 5.29’s won’t enable that. In summary, in the old days with 3 or 4 speed transmissions lower final drive gearing was essential when going to taller/heavier tires, for both low speed and high speed situations. But a modern 6 speed, let alone 8-9-10 speed transmissions, would seem to have close enough ratios that you can pick the rpm you need in most conditions with a slap of the lever.

Your position is that low rpm down hills more than make up for losses everywhere else?

You're wrong. Very wrong. Unless, perhaps, you only ever drive downhill.

Shoot, if you were even remotely correct, you'd be better off putting taller gears in your truck... mind some 3.08's or even 2.75:1... cause you should be able to lower the downhill RPM's even more, which, per your logic, will more than make up for the horrible fuel consumption every where else.

I didn’t say anything of the kind. I said that least the high gearing “ does help” recover losses. Look, I have over 60K miles on a 3rd gen Tacoma with stock gearing and auto trans, and slightly larger than stock Load Range E tires. It’s far from perfect. I’m just saying that you don’t need to drive around in “D” all the time ... with a 6 speed you can pick your rpm and throttle opening to HELP SOME, not SOLVE ALL, of it’s issues. In MY OPINION, regearing a stock truck seems excessive. And for what it’s worth, I’m a retired mechanical engineer who understands the basic math of gearing, tire size, and rpm, as well as rpm/torque curves and brake specific fuel consumption. End of discussion.

have you been on the internet before?

Who said anything about regearing a stock truck?

End of discussion... because you don't want to discuss it. Got it.
