Why my Taco always shifts early?

My Taco is a 2001 3.4 V6 with automatic transmission, 4x4.
Noticed it always shifts at 4800-4900 rpm at WOT. ECT on or off.
The only way to get it to shift at 5500 red line is to manually hold the gear selector.

I used to drive a 5 speed 4runner, so this is new and strange to me, please help me~~

 

so you want to blow up your engine and/or tranny by requiring it to reach redline before shifting?

you do realize redline is the limit point where things start to wear excessively, get damaged, or fail don't you

 

My 3.4 starts to scream at me right around 3k, I never go past 4k even with my supercharger on. Just sounds and feels like asking for trouble.

 

Rev limiter is set at 5700 rpm for both the 2.7 and 3.4 , also sitting on the rev limiter doesn't hurt a motor

 

I am not sure how everyone's V6 is, but around 3100rpm the engine tone changes and does not sound too terribly happy... it still pulls strong just don't think the 3.4 was designed for any high RPM work.

I'm with you, as long as you keep up with the maintenance, it doesn't hurt it...of course its not like keeping it at 5500 rpm ALL THE TIME....

 

that's when the torque curve starts really kicking in, you can actually feel it pull more above 3k

 

Mine is supercharged and has 7th injector, starts to pulllllllllllll once above 3000 rpm

 

Believe mine shifts at about 5200

 

Random question for you...after adding the 7th injector, did you notice that you get boost faster when accelerating in first? I have a stock supercharger setup and I always have to shift into 2nd before I get any real boost, kind of sucks because I don't get to jump off the line as fast as I think I'm capable of doing. Wondering if the 7th injector might help

 

Yup.

 

100+ mph?!? Image how fast you could go without your parking brake set!

 

km/h. parking brake isnt on. i have it rigged so the drls dont come on.

 

I was kidding. But interesting. Why not pull the bulb out of the cluster?

 

im lazy.

 

Just put it in 4Hi if you want some real boost off the line. LOL!!!

 

I've recently gone past 4K rpm and it was amazing. (I've owned the 3.4 for a little over a year and never done it before)

 

Hows that even possible.
