Toyota 4Runner transmissions and you!

[Foamermetal]

Don't know if this is the proper place to ask this. I have broken the gray plug on the right side of my 2000 A340E (2wd) transmission that plugs into the park/neutral position switch. The harness side wires have pulled through the terminals and I have no way of knowing where they terminate in the plug.Does anyone know the colors of the wire and into which hole they go?. I can get the terminals and the proper crimping tool. I'm just color blind and want to do this right the first time. Thanks.

Great post, great info, thank you.

I was curious what your thought is about the not flushing of older transmissions for fear of flushing out the friction material or wrecking them in some fashion?

I notice that you have a 2000 v6 auto alumarine.

I was looking at one of those:

2000 TOYOTA 4RUNNER LIMITED, CLEAN TITLE, RUNS GREAT

I've just begun to learn about 4 runners though.

Trying to avoid pitfalls.

I have the same year model, trim level, and color as that one.

It looks like that one is only a 2WD though, if you care about that.

Great question. After reading various opinions on the subject, will be nice to get what appears to be a professional take on the flush vs drain and fill option.

Currently setting at 135k with not much history, and want to do what's best for longevity of transmission.

To the OP -- Thanks for the in depth informative info.

Yeah, I missed that.

I live in the hills but I've gotten by without 4 wheel drive, still I think it's going to be a requirement.

Thanks

Personally I would just buy matching working components and use those or buy matching cores and rebuild them. Swapping can be done you just have to get all the right items matched up and every situation would have to be examined individually with all the different factors you could run into. For instance if you are already 4wd and trying to turn a 2wd unit into a 4wd unit because you cant find a replacement 4wd unit or core to use? is the 2wd unit a no pipe, 1 pipe, 2 pipe? is it an E or H model etc. Are you 2wd going to 4wd? so many options and scenarios.

I've been looking at swapping to 4WD. I figured it would be easier to just get the whole unit, and your post confirms it for me.:surfer:

I change my fluid every 2 years or 30k miles no need to flush if you do that.

change every 2 years or 30k. not only is it a coolant its also a hydraulic fluid and a non conductive fluid . When it stays in there for years and years it looses its ability to cool, act as a hydraulic fluid and it becomes conductive with all the particulates that are deposited from the clutches etc. bad things happen when you have electrical items submerged in a conductive fluid.

pm me ill send a diagram ( I sent a schematic via pm to a non public album, you must add me as a contact to view it i think)

And with a drain plug it's so easy.

Trans Fluid & Filter Untouched Since '06, Now What?

Got my '98 3.4V6 with Auto Trans in 2006 with 75K. Now has 199K.
Have never changed trans fluid or filter.
Noticed some "shuttering" or "tugging" while driving at constant speed.
Checked fluid today after 15 minutes of driving. (in Park while idling)
Fluid below lower "Hot" notch a little - maybe 1/4" or so.
Added quart of new fluid, drove and rechecked, still low.
Not sure if the extra fluid stopped the shuttering.
What to do now?
I have been told not to have fluid changed or trans flushed at this point.
Add some quality trans fix fluid? Top off with more fluid?
Any comments/suggestions would be appreciated!

I hope I'm misunderstanding this, but you went 120k+ miles without changing the fluid or filter? :wow:

Life is busy, two kids through college, elderly parents.....

Still looks great and runs great, just want to do what I can to keep it going as long as I can.

Well, I am not very experienced with transmissions so you may want to wait until the OP responds. I can only tell you what I learned from my situation with a failing torque converter.

Was the fluid black and did it smell burnt before you added the quart to it?


Here's what I would do:

First and foremost, find the source of the leak for the transmission fluid. Either fix it if it's simple (drain bolt) or deal with it and watch the fluid levels.

Fill the fluid to the appropriate level and just continue to drive it until it dies. That could be 2 months or 2 years. Who knows. Impossible to know what damage has been done to the transmission, if any, without disassembling it. Definitely do not flush it. You might be able to get away with a fluid and filter change, but again, hard to say.

In my case I left it leaking and added fluid as necessary not bothering to change the filter. I knew the transmission would need to be replaced anyway.

Trans fluid was red and did not smell burnt before adding quart of fluid.
Have not noticed any oily spots on driveway or parking lot..but seems like last oil change I noticed some seepage. Don't ask how long ago that's been! It's way over due too!
I will stop at auto parts store and put in some good quality trans fix fluid in when I top it off.
Last week I pulled a fairly heavy trailer with small tractor up a long steep hill, and it did great with no hesitation, well after I first noticed this issue, so I hope topping off fluid keeps it going.
Thanks!

Have you tried driving with overdrive off to see if the problem persists?

I believe adding the quart of fluid nailed the problem! Still need to top it off, but hopefully that fixed it.
It seemed to run smooth, in and out of OD. Thanks.
