99 Lexus ES300 U140E Tranny dead

Sep 06, 2005 1 Replies

I have a 99 ES300 with approximately 96k. Recently it quit pulling in all forward gears. (U140E Trans) Not willing to fork over $2900 to the dealership for a reman I pulled the trans out and took a look since in my previous life I did a good bit of trans work. What I have found is the the forward planet gear set came apart damaging close to $3K worth of hard parts (4 pieces). While I have seen failures like this before they are fairly rare and I certainly didn't expect to see it in a Toyota with less that 100K. Has anyone else seen this kind of failure in a U140E and is it typical for this transmission. I have scrapped my plans to rebuild even though I am already $400 worth of parts into it and have ordered a Used Trans with 21K miles. I am curious about the quality of this particular transmission type now. Has anybody heard of these new Toyota transmissions being prone to catastrophic failures like this?



A friend had a problem with the transmission on his '96 Camry with 150k miles. I don't know what actually broke but the fix was a replacement transmission. He was not very meticulous about changing transmission fluid and he has a habit of changing from forward to reverse and vice versa before the car came to a complete stop, so I thought those factors contributed to the short life span.
