2007 Es 350 Transmission Flair

Recommended Posts

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 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.

      If anyone could help it would be gladly appreciated. I have a check engine light on my ls400. Took it to autozone to let them use the code reader on the car. They told me one of the solenoids are bad on my transmission. If anyone can tell me, or help me how to correctly replace the solenoid and what tools I need I’d very much appreciate it. Or should I just have a shop do it?? Thanks

      Hey everyone,
      I have a 1999 GS400 with, (and I know it's a lot), 350,000ish miles. Shes pretty old, but the engine runs great and there are no issues on that part. However, my check engine light has been on for a pretty long time now and my OBD reader throws a "shift solenoid c electrical failure" code. My transmission shifts extremely hard, and I do not believe it shifts passed 3rd, but I am not 100% sure on that part yet since there is no clear way of me telling. It takes a few seconds when I put my foot down for it to downshift. The fluid is in moderate condition, no sign of transmission wear at all.
      But this is where it gets weird.
      This has happened I would say maybe 3 times now, but the check engine light will go away and the transmission will go back to normal.
      Also, i should note, when the CEL is on, the digital shifting w/ the steering wheel buttons does not work; however, when the CEL is off, it does.
      The few times that the CEL went away, it was relatively warm outside, and it lasted about 15 minutes each time. Then out of nowhere, I would hear a thunk, and the CEL comes right back on. The last time the CEL turned off was about a month ago, and it has been on ever since then.
      I have read up on a few forums on here and on other places regarding this, but no one's seems to be working & then not working like mine is. I'm hoping that since it comes and goes that i can simply just replace the solenoid and not have to worry about a rebuild.
      If anyone has any insights or suggestions please let me know!

      Recently purchased an RX-300 AWD. 208K Miles. Just had Timing Belt/Water Pump/Plugs/VVT Servo Valves changed. It runs great (other than the world's most annoying sunroof rattle...but that is for a different thread). BUT....It has a very odd transmission problem.
      Only when it is very cold, it is hard to shift the transmission out of the Park position. It acts like there is a solenoid or a release valve after you push the shift button. You have to fiddle with it for about 15-20 seconds then it shifts out of park. Once warmed up even 5 minutes and for the rest of the day, it shifts in and out of park perfectly. Trans is otherwise acting absolutely fine...and yes, I plan to have it flushed by the area's top transmission shop and have them install a new ATP B187 trans filter I purchased.

      I just wanted to say before i continue, I'm 21, Female and this is my first car I've owned for about 3 years ( not that any of this is really important)I'm starting to want to learn more about cars and how to fix my own problems and save money instead of relying on a mechanic. So far I have repaired my busted front bumper, repaired and replaced R headlight housing and bulb, and Replaced an 02 censor.
      I'm having issues with my transmission shifting gears in cold weather, but it runs like a dream in the summer. This was a problem last winter but wasn't as bad. Before, while accelerating and merging over on high-way, it wouldn't use the 4th gear at first but then it would shift gears after driving for a bit. Does the same problem now, but won't change gears at all or takes 10 mins+ to shift itself. sometimes has issues shifting 2nd gear to 3rd.
       es300 is 206xxx miles, 1999 model, and the transmission was rebuilt July 2016. I'm afraid this might have something to do with the previous failing but i want to try and fix the issue myself but can't figure out why this is happening or where to start. Coolant meter is always where it should be, oil is changed religiously, 02 sensor bank 1 sensor 2 needs to be replaced.
       4000 rmp at 75mph... (o/d drive is not on). Sometimes when braking hard or getting off high way, doesn't accelerate as it should, almost as if it skips 2nd gear. Accelerating 1st to 2nd at stops goes back to normal if I restart engine. 
      Over all, why is this happening and how can I fix it? Only happens during cold temperatures below 40.

      Hi, I've recently noticed that the transmission disengages going down hill, and then going up hill it engages again....
      Has anyone heard of this before?
