title is typom it is lubrication additives


Hi all,

My 06 SR5 has some problem when gear changes from start>>1, 1>>2, 2>>3, 3>>4, but until 3 severe, but 4>>5 minor...
Automatiac trans.
so, I purchased some fo transmission treatment ( three different brands).
But I realized that my car doesn't have oil check pipe(hole) so I am wondering where can I pour this treatment into??
I think mine is SEALED one.

1) these treatment really help to make the gear change smooth?
( right now, almost stop and start when gear change time during driving, it's a little bit dangerous)

2) if needed, how can I put it in?

Thank you so much!!!

Your transmission is sealed and unless you're a good enough mechanic to tear it down you're SOL.
 
First of all, thanks for information and advice.
Please allow me to tell you what happened on my lovely 4runner;
2 years ago, at that time, I didn't know my trans is sealed one, so I just stop by auto mechanic shot I usually went and asked to transmission oil flush and change, then they just said OK and charged me some money( don't recall how much, but I think around $150~$250), so I paid them just trusting their words.
Now I know either (1) they didn't change OIL but charged or (2) flushed out oil and pumped in new oil...
If they did (2), then this could cause my problem?
at this moment, how can it be fixed? overhaul?
Thanks again
Eric
 
If the gear changes are subtle and not very harsh you might be able to just change the fluid out.

The unit is a sealed unit and a transmission flushing machine was probably used. if so, they may have used the wrong fluid or the wrong amount. In any case, I would reccomend that you attempt a proper ATF flush with Toyota WS Fluid and have it done by someone who has experience with sealed transmissions.
 
Thanks BlackWorksINC....

One more thing before I go to mechanic shop,

My T4R has 250,000 miles on it, this big mileage has something to do with my trani problem?
What is the life span of trani oil for dealed trani like 06 T4R?
Thanks,
Eric
 
That is a lot of mileage, but there are members in the 300k+ club who are still on their original transmission. Life expectancy on a transmission varies due to the abuse its had to live with, much like an engine so I can't really tell you for sure how long it should last. But in my experience, Toyota Transmissions hold out for a long while usually if taken care of minimally.

The fluid is supposed to be "Maintenance-Free" and "last the lie of the vehicle" but we recommend around every 100k or so to flush the system or at least do a drain and refill.

It could be indications of the transmission starting to show sign of wearing out, or it could just be signs of the transmission needing new fluid. I honestly can't say for sure over the internet without actually test driving the truck, but usually the first thing I recommend is fluid to rule that out. Its amazing what fresh ATF can do for a myriad of transmission problems, its a very stressed fluid. It has to double as lubrication, hydraulic fluid, cooling, and filtration & sacrificial functions as well.

In my personal opinion, from what you have said, I think it would benefit from a ATF flush and that should solve most of the issues.

250k in 6 years. 41k miles a year, that is almost 3 times the yearly average; which I suspect means heavy highway miles.

Highway miles are MUCH nicer on a car.

I bet that is original trans fluid and that is your problem. Take it to Toyota and have them do a fluid exchange first and see if that helps.
 
I'll bet the wrong fluid was used. You need to have a Toyota Stealer do a complete change using the "WS" fluid (low viscosity synthetic). You may have damaged the trans.

Note - These sealed trans do not need to be flushed unless the fluid gets damaged (excessive heat). If this happens you get an idiot light on the dash. Maintenance free MEANS maintenance free!

I find that difficult to believe, a transmission sheds a lot of material over the span of 100k let alone 250k. It does a lot of jobs and I just can't believe that after 100-150k the fluid is still going to have the cooling, lubrication, friction, and other desired effects as if it were new. I think the fluid will last a hell of a lot longer than traditional fluid, but it still is going to break down, collect particulates, lose its efficiency, ect.

But I am sure they probably used the wrong fluid, or if they did use the right fluid, they didn't fill it properly (these sealed units seem to be a little more finicky about too much or too little fluid)
 
I would say the shop that flushed it really did flush it which depending on too many factors to list succeeded in loosening crap that had built up. The end result was that some small particle ended up getting sucked into a valve causing your current issues. The good news is you got some pretty decent miles out of it.
 
Thanks everyone, it helps me a lot...
I know I used a lot of driving my T4R...most city and coounty load, not highway...
I love my T4R, it's really GOOD car....

Which shop you recommend? Toyota Authotized Service? or local private mechanic shop?
Around how much it could cost for ATF WS flush/change?

Thanka again and have a nice weenend all...:thumb3:

I had it done for 258. This was a dealer in D.C., so really expensive area. So, prices may vary.

But if any dealer tries to charge you more, and you don't live near D.C. (which is an insanely expensive area) then you know they are ripping you off.


Note: You want a fluid exchange, not a flush. In particular on your trans, with as many miles. A fluid exchange will remove all the old and will be VERY easy on your transmission.

If towing, the WS fluid should be replaced every 60k miles according to my '08 Scheduled Maintenance Guide.
 
Yeah, I took mine to Toyota for the tranny flush and timing belt. That way I only go there every 100k miles.
