Ok, i have an '05 auto xB with roughly 32K on it.
and lately i have been noticing that the tranny sticks in high rpms and wont go down, sometimes it'll go donw after a couple mins, but other times, it will only go down if i turn off the o/d then turn it back on. Just kinda wierd, wondering if it will cause any problems.
I can't figure out, what the problem is or if the even is a problem, can anyone help me?

Chopra are you capable of doing a tranny fluid flush? If you are, I would do a switch over to synthetic tranny fluid and see if that stops the issue from occuring.

how would I do a tranny flush? what does it entail?
I only have simple handtools

Here is an AMSOIL page on synthetic ATF, with a link to a PDF DIY file on how to change over:
"ATF and Transmission Filter Change Procedures"
https://www.amsoil.com/StoreFront/atf.aspx
It says "using flushing machines does not address the need for cleaning the sediment in the transmission pan, cleaning the magnet inside the transmission pan, or changing the transmission oil filter". The DIY recommends removal of the pan to clean it and change the filter. It would take a socket set, a fresh gasket and a new filter.

Um, no one makes full synthetic techIV Toyota trans fluid. Use of anything other than the synthetic blend OEM fluid may toast the tranny. Just change out the old with fresh techIV and it should shift like new. At 32K it is over due anyhow. I'll be changing mine every 20 k from now on.

Ok so now my curiosity is peaked. Anyone who can help I really appreciate some good sound info. I changed my tranny fliud over to the Amsoil. I love it I think it shifts about the same, but it does have a smoother accelleration and seems to run alittle cooler. That being said, I was reprimanded for changing from the Toyota fluid by a few here on this site. I talked to my Toyota guy's and they said it is not recommended by Toyota. They also said they run synthetic in some of theirs. So what I guess what I am asking is does anyone here feel strongly against synthetic and why? What is the evidence to back it up?
Thank you

Thank youYou are taking a huge gamble with your tranny. I looked long and hard for a full synthetic tranny fluid and could not find one that was 100% replacement for the Tech IV stuff. I also found out during my research that the Tech IV stuff was already a synthetic blend so I'm sticking with it just to ensure a long lived trans life. I'm also gonna change it every 20 K just to make sure.
I've heard horror stories about how other fluids work for a short time then the tranny goes south. Then they try and have it warrantied and the dealer finds out they didn't have the recomended fluid in it and say they won't cover it. :nails: There must be a valid reason no one carries a direct replacement for the Tech IV stuff or every manufacturer would have something that would work for sure.

well then what exactly should i do?
should i take it somewhere is this something i can do?Just go to the dealer and buy a large can of the Tech IV fluid (I think it was metric but a gallon). It's like 30 bucks roughly. Then you'll need a 10mm socket head socket to remove the plug in the trans pan and put it up on jack stands. Warm up the trans before you start. (it will help the trans drain better)Then measure the amount of fluid that comes out (don't rush it and let it drip for awhile till it stops). Replace the plug and add the same amount removed. I did mine at 25K and wish I did it sooner. Mine was pretty dark but it shifted just like new after I changed the fluid. Good luck and hope it works for ya. :bow:

yeah dude , ive worked for hyundai, isuzu, and currently at acura, and switching outside factory ATF is a major no no, just keep it fresh and factory, every 30,000 is best, every 20 is a little excessive, but does ensure no problems, fluid breakdown and contamination is the biggest auto trans killer, i'd say 90% of the ones i have changed died due to this. the factory produces specific fluids to run thier systems, and thier engineering depends on it, back in the day any generic atf would do, but i'd say mostly around 99-now it has been pretty specific to the manufacturer and the tranny will work best with it and last longest. Acura is even specific over their differential fluid, for example. I feel that synthetic is best for your engine, and stick to factory for the rest, even brake fluid

What I did to change the tranny fluid was I bought 8 quarts from toyota, drained the tranny, that is about 4 quarts. I refiled it and then drove it about 1000 miles and drained the tranny again and added the other four quarts. The service guy at the dealership said that will get about 90% of the old fluid out. The car has 30K on it. Shifts like new. But you have to use toyota fluid.

Thats sounds like a good idea.. How much was 8 quarts of it?

is there something special i say or do i just ask for "tansmission fluid for an xB"?

also, where is the plug i drain from and where do i put the new fluid in?

sorry never even looked at my tranny before so I am a noob at this part :loser:

Um, couple of things here. Although you CAN dran/fill/flush the tranny fluid any time you want in an auto xB, you really don't NEED to. The Toyota Type T-IV tranny fluid is designed for long life use and, technically speaking, should easily run past 60K miles without issue.

As for your shifting issues, is this happening only when the car is cold or all the time? When the tranny is cold it WILL hold a lower gear to heat the fluid faster rather than stress everything by running cold fluid at a taller gear. This happens on most Toyotas but is really noticible in an auto xB simply because of the gear spacing. This happens on new ones too.

Hopefully that helps.

-Alex

BTW, yeah, just use the Type T-IV fluid. Any Toyota dealer will have it and you CAN just ask for xB tranny fluid. They will know what you need.

I have had the exact same problems in my 06 RS2 xB. It can happen anytime from driving down a side street to just all of the sudden on the freeway. Happens in o/d and non o/d. I have had it in the dealer several times and I always get the same answer..."No problems codes recorded"

That with a host of other transmission problems I am about ready to lemon it or ask to have a new transmission put in, but I would much rather have it fixed.

They haven't been able to come up with a solution or any recommendations even after repeated meetings with Scion/Toyota reps.

If you come up with something that works please let me know!

I own a Toyota Echo and I think it has the same transmission as the xb, xa, yaris and vitz . I got the same problem awhile back but only when the car was cold. This fall I put 18" rims on my ride and now it holds 4th gear real tall. I can switch to neutral then back to drive to fix it.

On another note, is there a racing type automatic tranny for our cars? switching to a manual shift unit looks expensive. Anyone know how much that type of thing runs?

can't give figures, but i know alot of people do the auto/stick changeover fairly cheaply with used parts and a new clutch. I'm sure theres a donor with your name on it, and a racing auto trans. would cost more than just goin' stick.. but this is my first trip to toyota land and have never done it, so i may be wrong. For honda its simple, i know that much anyways.

I didn't even think of using donor parts :doh: There I was trying to get all new stuff. Alot of the turbos and superchargers are compatible w/ the stock manual trans as long as the clutch is upgraded.

Toyota T-IV is a long life trans fluid designed for toyota transmissions. The fluid has the a certain friction coefficeint needed to allow for slipless clutch pack engagement. And the additives needed to ensure seal compatibility and long fluid life.

T-IV can go at least 50,000 miles befor the addivitves start to break down, additives breakdown befor lubricity is lost.

Any aftermarket trans fluid (synthetic) you put in there does not have the friction coeffcient needed for proper clutch pack operation or seal compatibility, and will most likely make the clutch packs slip. creating heat causing thermal fluid breakdown and fluid contamination. eventually buring out the clutch packs which in turn burn up the trans bearings and gears fom all the clutch material in the fluid.

Stick with the Toyota T-IV.
