2007 Es 350 Transmission Flair

[Jelley]

I have 2007 ES 350 with 145,000 miles. Last year started having transmission flares intermittently, couldn't duplicate at dealer. It went away completely for past 6-8 months and now started up again. My question is, is this symptom of a possible catestrophic failure or something I can live with so long as it is not happening often. Due to age of car I don't think I will keep more than another year and sure don't want to put money in it. I saw multiple posts about this problem but couldn't determine the severity of the problem or is it just a nuisance?

I would update the transmission ECU. Some say that can fix the flare.

Mine has the same mileage and had the flare for at least 100,000 mi. After the car warms up it goes away. Haven't noticed it getting any worse...

Did you update the transmission ECU?

At 162000 mi the flare hasn't gotten any worse, after one complete upshift to 6th it usually goes away..No software update, mixed reviews on that fix.

I did a lot of research and I came with simple solution.

1. Drive the car for 15-20 minutes, the transmission needs to reach the working temperature;

2. Park the car, open the hood, open the fuse box next to the battery;

3. Remove fuses #21, #16, #37, #38;

4. After 15 minutes return them back (#21 is a 30A fuse, #16 is a 10A fuse, #37 is a 15A fuse, #38 is a 10A fuse).

5. Drive the car for 15-20 minutes hard, it has to shift over 3000 rpm, do a lot of kick downs, let it rev past 5000 rpm, that's the best way for the transmission ECU to relearn;

6. Park in in your garage and try it next day. This worked for me.
