I have a 2009 Aurion. This Winter im noticing a delay in drive when cold. It goes into drive fine. But shifting up from crawling pace it's indecisive in the first couple of gears
Could be something in the TCM computer. In the USA, some my 2007 lexus es350 had some kind of software update to transmission computer in about 2009. It has the u660e. A family members es350 did not have the update and has had severely delayed shifting which seems like its slipping, but it is smooth. It happens usually for when it is below freezing. Good news is that it has been like that for 70k miles and has 170k total, so it doesnt seem to affect longevity.
There are several valves in a U660E valve body. It would be best to refer to a tech service for an exploded view of the valve body to locate the valve in question and its function.
My 2015 Sienna with only 5,000 miles has this transmission. Had that whine since new, the case is not causing the whine. I don't think it's the transmission at all. I've heard it's exhaust resonating and that weights stop it, but it's harmless... IDK to me it always sounded like a power steering with low fluid.. But my Sienna doesn't have a ps pump, does you Avalon?
Proper use of transmission fluid today is critical especially in Toyota. To deviate from the correct fluid can cause short-term drivability or long-term durability issues. It is best to verify and use the correct fluid.
Here in the UK it’s on the 2.2 Diesel Avensis. Problems are very common, perhaps it’s because of too much pressure and torque from the diesel engine that the transmission can’t handle
If I replace transmission fluid , is old fluid still inside the hydraulic pump body ? Is there a way or a hole for the old fluid flow out when transmission fluid change ? Please reply and thanks !!!
Hi, here is the response from Transtar: There will be residual fluid left in the transmission and torque converter during a “ pan removal service”. In the case of a U660E you would be able to extract approximately 3-4 +/- quarts of fluid depending how long the pan and filter was left off. This total is about half of what the transmission and torque converter utilize when completely full. As for whether there is a way or a hole for the old fluid flow out when transmission fluid change: There is no way to remove all the fluid form the transmission and torque converter when performing a “pan removal service” on a U660E transmission. The torque converter does not utilize a drain plug. There are Transmission flush services offered by many repair/service shops that will remove close to 100% of the existing fluid with new ATF. A specific machine is required for this service.
My 2007 camry drives like a dream when i accelerate it pretty hard from 0 miles an hour and it slams into gear sometimes when i press the gas pedal harder from 35 miles. It feels like it slams into one gear only. Could this be the issue?
@@ChristopherGuilday it would be a relief if it was only a motor mount, but there is no vibrations when i start the car or turn it off, tried the manual mode and i only get that slam when, for example, i downshift from second to first gear
After a rebuild a U660E shop used mercon V, which I replaced for WS after as soon as I knew. what could cause a hard shift from first to second gear? and sometimes from 5th to 6th gear also
Ams oil is best I’ve been using amsoil since 80k miles religiously change oil including trans fluid it’s a 2007 with 170 now engine purs trans is smooth I used to use ws fluid but they use the minimum additive in there fluid jus cuz it factory don’t mean it’s the best u can get
Thanks for the information just watching this now, I wanted to purchase a 2015 rx350 with this transmission any thoughts and advice to prevent this issue or is that possible, can you prevent by changing the fluid? Anybody's input is welcome.... Please advise I'm nervous to buy this vehicle I thought the 2015 rx350 had one of the most reliable 6 speeds Toyota did.
Following the maintenance steps found in the vehicle owner's manual is typically the best approach to keeping the transmission functioning properly throughout its service life.
Thanks for the reply I will be looking for an rx350 2015 model year defiantly looking for one with around 50-60 thousand miles on it first thing I will do is change the transmission fluid. I've always had OCD with changing transmission fluid because that's how you get the life out of them. The main problem with buying one with 80-90 thousand is most people don't change the fluid and then you stuck with there issues. Love Toyota & Lexus I've owned two Camry and three different models for Lexus, thew one thing I do not understand is if they had this TRANMISSION in production from around 2006 past 2015 you would think they would have worked out all the problems with this transmission, not that its problematic but, usually there really good with correcting problems over time, come on Toyota bring your A Game. I am very surprised that the rx 2010-2015 last so long because it sucha heavy vehicle to pull and you have all that strain on the transmission. I guess its not like the is or gs were you have significant more horsepower and torque. @@bobbymace5715
@@joshuapressley4441 You should consider the audience that Mike's addressing in the video. He's discussing the issues that technicians encounter once a transmission has failed. In most cases, whether it happens at 75,000 miles or 275,000 miles, the failure will take place due to one or a small handful of parts that fail. Mike is telling the techs to look for the most commonly encountered failure points and isn't discussing the overall quality or lack of quality for the transmission.

The bearing to case bore wear issue is a torque capacity problem involving the basic design of the transmission. The harder that the vehicle is driven the more likelihood bore wear will occur. To my knowledge, there has not been any type of reinforcement by the OE or aftermarket to eliminate this issue.
@@TransmissionDigest From what I've read so far, the bearing to case bore wear seems much more prevalent on the V6 models vs the less torquey 2ar fe inline four engines. Is that correct?
does anyone know if the u660e from a 2gr-fe aurion will fit a 2gr-fe estima? Would there be any differences?

Does this also affect the U760E and U760F transaxle?
Need so information on the valve at the back of the valve body?
There are several valves in a U660E valve body. It would be best to refer to a tech service for an exploded view of the valve body to locate the valve in question and its function.
You ever see this problem on U760E fwd transmissions also?
much worse, my moms car trans model: u7603 just die with 233,000 miles on it
Hello! Could the case bearing issue be the cause of slippage and shaking/shudder while reversing uphill will you point to something else?
If you’re going to go through the hassle of replacing/refurbishing the transmission case, just throw an OE reman transmission in and be done with it.
Thank you great video
Would this create a whining noise in every gear including park and neutral? 2014 Toyota avalon 67,000 miles

I doubt you'll ever have a problem, the Avalon is fairly light. The Sienna is a pig, my weighs 4,700 lbs.
Muchas gracias sr.
Can u talk about the importance of fluild types .such as type 4 an the new stuff
R they compatible? 2010 avalon.thanks

Is this a torque converter automatic transmission?

You sure it’s not a bad motor mount? Try putting it into that gear manually and then mash the gas pedal, if it still slams than it’s your motor mount.

What about a 2016 es 350
Witch transmission do you think is better in reliability the U660E or the U151E on a Toyota Avalon
U660e has better reliability

@@Shade_Tree_Mechanicwouldn't the weight of the vehicle be more of a factor like the pig of a Sienna that weighs 4,600 lbs?
Did Toyota ever revise the design?
