The rest of these jokers set the bar pretty low :bounce:

Your usual good work Jeremy. Thanks.
Yeah...I figured on the 5th Gen 4 Runners the D light would be used in place of the Tacoma A/T Temp light which I have on my '15 Tacoma.
I've yet to tackle this as the 4 runner is young, but have read many WEB comments regarding the timing of the shift from N-D and D-N.
Seems like you may have to work at it B4 you can get D to flash.
Practice, practice, practice.

I used that method recently. Note the moving from N to D for 6 seconds step.
The way i did it was 6 shifts between neutral and drive, maybe i didn't do it long enough.
Are you supposed to take out the jumper wire right after you get it to enter into the temp check mode? thats what it looks like, or do you just leave the wire in until you are totally done? I was just thinking if you pull the wire out it would make it come out of the temp check mode.

I have learned that with Toyota, if they say 3 seconds they mean 3 seconds. Not 2.9. not 3.1. Not 3.05. They mean 3.000 seconds! Good job [MENTION=78273]Jeremy556[/MENTION]. I try to bring the bar up but I just keep getting dragged down by the man...

Yea, it's at least 6 seconds, so it will take more than 6 shifts if you are shifting in less than 1 second. Correct, remove the wire once the light comes on for 2 seconds. It stays in temp check mode and will continue and the D light will come on when it reaches 104f
Ok, thanks. I think that answers my question. And the other thing I was looking for was the AT temp light to come on instead of D, because that is what it said to do on the site that i was looking at but it was for tacomas. thanks again.

Engineers look away.

proper level
well I got it to work tonight, I got under there and pulled out the check plug and it flowed out pretty quick for a couple seconds. But by the time I got out from under there and back with a new crush washer it was just barely running out the hole and just dripping off the bottom of the pan, is that where the level should be at?

The instructions said a dribble.
Somewhere between a drop and a stream. Lol
Most overfill, then drain it to optimum level. You have a six ounce window.

Just a FYI for everyone,
if you have a scangauge II, you can use it to check your transmission temps, by creating a new entry in it. it is listed in the Tacoma forums and works on the 4Runner (I use it)

No need to even leave the forum :biggrin1:

In post #9 of this thread, Jeremy556 indicates that the jumper wire can be removed after temp check mode has been entered.
Post #702 in the following was supposedly written by a dealer tech. He emphasizes the importance of doing this:
https://www.tacomaworld.com/threads/how-to-drain-refill-automatic-transmission.63851/page-36
He makes other comments further down relevant to the business of changing A750E/A750F transmission fluid. One I especially noticed was putting the system into learn mode following the fluid change. That can be accomplished with Techstream. Not everyone has it. On a Camry forum at toyotanation.com, another dealer tech indicated the following could be used to put later model Camry's into learn mode:
Disconnect the battery ground and wait 10 seconds. Touch the ground to the positive and hold there for 10 seconds. Wait 5 minutes. Repeat the ground to positive for 10 seconds and then reconnect. This puts it into learn mode. Take it on an aggressive test drive on 95 Or 476 or 276. I suggest you do this AFTER replacement of the filter.
I asked the tech on the tacomaworld forum if this would work on an A750x transmission(the toyotanation tech did not respond to my PM). Here is his answer. One part - slightly different:
Doing the battery cable stuff will erase the memory, but you don't want to do an aggressive test drive. You want to let it warm up fully after starting, then drive with light to more moderate throttle in a stop & go pattern. Like a neighborhood. This allows the ecu to learn how much time is needed to shift each gear as it compensates for wear in the transmission. After about 10 miles, you're done. Then you can drive how you please. You never want hard throttle during any relearn because all memory has been erased, shifting, knock learn, ignition timing, fuel trim. Everything's been set to base setting & hard throttle will not learn anything because it's going to max out all values to produce maximum engine torque.
Would be interesting to hear what BlackWorksInc thinks about this.

Dunno if it helps, but you can also get a cheapo OBDII bluetooth reader and download the Torque app on your phone (all in at ~$20) for many live readouts.. Including trans temp and converter temp too.

Your post used to have a PDF sheet showing the instructions. Do you still have that PDF? Can you repost it?

Here's some info. Use at your discretion. 2nd Gen Tacoma & 5th Gen 4R both use A750E(2WD transmission) and A750F(4WD transmission).
