Does anyone know of someone that makes shift improve kit for the automatics in a second gen 4Runner. Or if there is something you can alter in the valve body to tighten up the thing. I know they are made for every chevy, ford and dodge tranny out there. Has anyone come up with something for us import guys? Especially when that tranny is so known for it's power loss.

Ya theres one out there called the r150f. Doin the r150f swap is the best way to make it shift better.

Poor man's shift kit.
Disconnect transmission "kick-down" cable from throttle body.
Pull the cable all the way out and fasten it in this position.
You'll get a much firmer shift.

^^ so youre saying to have the kick-down cable always taught?

bigtrucknwheels

hahaha, that sounds awesome. why not just use ECT Powar all the time?

turtle jim

Position of kick-down cable controls line pressure in trans. Relaxed cable, soft shifts, taught cable, firm(er) shifts.

power button raises shift point about 500 rpm's

Use both and get a more firm, delayed shift.

Try it !

Warning about the ECT power button- it disables the TCC lockup, so don't do that unless you have a BIG trans cooler. The A340 trans for the 3.0 has a 2800rpm stall converter that is designed to work with the TCC lockup to keep the heat down.

whats the down side ?? what does this do to the tranny in the long run ? there must be some price to pay

skife

pull the valve body off, put a heavier spring behind the accumulator piston.

you'll get much much firmer shifts.

Thanks poster!

the 5-speed swap is still going to always be better than an auto, even tho i just bought an auto, but if ur looking for straight performace than the manual tranny is the way to go

FredTJ

Of course there is a downside:



Line pressure that is too high will lead to shifting shock and consequent engine power loss due
to the greater effort required of the oil pump; line pressure that is too low will cause slippage of
clutches and brakes, which will, in extreme cases, prevent the vehicle from moving. Therefore, if
either of these problems are noted, the line pressure should be measured to see if it is within stan–
dard.

Wrong, the stall speed is 2200 rpm.

In almost every off road type environment the auto will perform better than a 5 speed (ducks as he opens up the can of worms again). Simply go to any type of off road comp and see what most of 'em are running, especially in the rocks..
Auto's rule in the rocks.
We take hard obstacles and make 'em look easy, the manul people take easy obstacles and make 'em look hard

Go through IPT, they do excellent work! They worked on my 84 vette and did a very good job.

Interesting, I didn't know that. Thanks for the info.

My lockup works fine when I have the ECT on. Goes thru all the gears fine and then you see the rpm's drop another 10-15% when the lockup engages. Other than slightly higher rpm why would the TCC not being on cause overheating? I have a 200-4R behind a built buick 3.8 V6 in a Nissan truck that has a manual Lockup option (can turn it on or off) and my tranny temp runs the same. Is this different in a Toy tranny? I do have a cooler though.

Dale - Did you see a difference in performance (power, economy) when you had IPT do your tranny or did it just give you firmer shifts? I think my tranny shifts fine when I have the ECT on. That's alot of money just for a tighter shift. Especially when Chevy, Ford, and Dodge shift kits are only $100-$150 and only take about an hour to do.
