Ok the pics to me show the "kick down cable" as the throttle gas pedal cable. The cable under that should be for cruise control. Please for the sake of my sanity someone correct me. My 94 5 speed had those same 2 cables. My 89 5 speed only has one, and no cruise control. What the hell is this guy talking about?

My 91 3.0L V6 3VZE Has three cables. One is throttle (obviously), then there is the cruise control, and a third one which I assume is the one being referred to as the "kick down cable". To be honest, I didn't even know about it until I read this post. I don't have a good picture of mine right now and I can't even seem to find one on google. I will take one tomorrow if and post it if someone hasn't already.

I'm not familiar with the 3.0s. I avoid them like... nevermind too soon. Anyway... I'm a 4 banger kinda guy. Simple for my simple brain.

But again, what he has circled and labeled is the throttle cable.

possible answer
 

Hey guys real quick...best way to check if its the kickdown cable, is to disconnect it and work it back to its base position (not pulled out). Test drive. If you shift normal on regular gas pedal pressure, your cable is holding you up. You can lube or oil it, but it juat might be old and binding. Ive done a few of these trucks. All of you are right about the temperature, but that cable will indeed cause a shift issue. Thats the passing gear cable and its the one that helps you drop a gear to pass and pickup overdrive. also check that fluid and that filter too. Hope this helps.

The transmission is operating normally, as soon as my truck reaches temp my truck will shift into 4th and then overdrive. This is the way they work, I believe its a emissions thing to get the engine up to temp faster.

4th gear is overdrive. Not 100 percent sure on toy trans but most shift though all the gears if your going fast enough, though the torque converter doesn't lock until the desired temperature is reached. Most people confuse lock up with another gear.
Yes they do that to warm up faster, both engine and transmission.

hmm on my 3.0 with a340h it definitely does not shift into 3th until the engine is up to temp. I will be running down the highway at 50 mph and 3200 rpm. then the rpms drop to 2800ish then again to 2200. So to me it feels like it shifts to 3th then overdrive. Maybe something is wrong with my shift solenoids lol idk is it normal for the trans to shift into 3rd with a cold engine?

Doesn't shift into 3rd or shift to 4th? When the RPM's go from 2800 to 2200 as you said is probably the converter lockup.
Every auto I've driven shifts all the the highest gear no matter the temp, and once it reaches operating temp the converter locks. Like I said before most confuse the converter lockup as a shift.

Interesting ....

But what does Toyota have to say about this? http://www.cygnusx1.net/Media/Supra/...taTech/h16.pdf

"When the engine coolant is below a predetermined temperature, the engine performance and the vehicle's drivability would suffer if the transmission were shifted into overdrive or the converter clutch were locked-up. ... The ECU prevents the transmission from upshifting into overdrive and lock-up until the coolant has reached a predetermined temperature. ...
Some models, depending on the model year, cancel upshifts to third gear at lower temperatures."

I don't know if the A340H is in the latter (no-3rd-til-warm) category; I don't spend much time driving mine in REALLY cold weather.

First I've heard about limiting a gear due to the temp. Might be a Toyota thing, I've never driven a toy auto.
On my Allison trans if the temp is below a certain point it will raise the shift points higher than normal to aid in warm up.

Yes, there are differences between manufacturers (and models, and years). Sometimes in surprising (to me) ways.

Fortunately for us, because our trucks are old enough there are a lot of the (otherwise copyrighted) Toyota manuals available online for free. I've owned my truck for 12 years, and I still keep coming across things that are different on the Toyota (specifically, my model and year) than on other vehicles I've worked on.

it does not shift into overdrive when the engine is below normal operating temp. you can feel it shift once its warm enough into od and then you feel the torque converter go into lock up right after.

I had a senior moment there, my sister has a Camry that I've drove several times and a guy I used to work with has a sequoia that I've drove.

If its a bad solenoid would that show up on the diagnostic code output ? My 1990 4x4 will not shift into overdrive.

Have you checked for codes? http://web.archive.org/web/201408161...31diagnosi.pdf
The diagnosis system can find an "open or short" if that's what you're thinking about as bad, but just like little kids learn right before Christmas, there are lots of ways to be "bad." If the solenoid was filled with "junk" from bad fluid, it might not let fluid through.

Check for codes first.

My 94 4Runner
 

my 94 4Runner des this and it has me puzzled. I can’t figure out it’s issue. Trans fluid level is perfect and sometimes it does great and the 4Runner itself is extremely cold natured and it does it more in cold weather. It will kick out of od on the interstate and it runs at 4K at 80 I really hate that it goes from doing good to no od it seems like. Suggestions?

There are probably somewhere between 15-36 posts above this, and the one you quoted covered the basics..

How about you tell us what you have already tested?
