I plugged in my code reader as my transmission is acting up and slipping at times, and i got the code P0770, Shift Solenoid "E" Malfunction. Anyone else get this before? If so, what did you have to do to fix it? This is on a 2001 ES300.





Thanks in advance!

 

Quick update, I erased this code, and went for a drive. It drove perfectly fine...perhaps there was a glitch? I will monitor it if it does act up again and see what codes it throws out then.

 

sorry replied to wrong post

 

If you're experiencing trouble with your transmission solenoid and throttle/pedal sensor, it's best to consult a mechanic for accurate diagnosis and resolution. While a dirty transmission fluid could potentially contribute to the solenoid issue, it's advisable to have a professional inspect your vehicle. The code P0121 related to the throttle sensor may be connected to the limp mode. Check the sensor's wiring and connections for any damage or looseness.

I had a similar problem when I just purchased a 2000 RX300 front wheel drive, 24-year-old with 65,000 MI. The transmission shifted great for about a week all of this time there was a check engine light on. Then I tried to start driving it and it ran fine in the morning but that afternoon coming home from work it would not shift into fourth gear (overdrive). I read all I could on these forums but nobody really pinpointed the issue. Someone said limp mode because of check engine light. I went to AutoZone to try to delete check engine light. They read the codes and it said misfiring. They could not erase the CEL. So I borrowed another one from a guy I worked with and cleared the check engine light. Drove it and it shifted great again. Check engine light kept coming back on so I purchased the xtool D7 and it told me exactly the cause. It was Bank 2 air fuel sensor. A lot of people and even dealership sites called it oxygen sensor, but it is not. It is the air fuel sensor right below exhaust manifolds. I switched the two sensors to be sure and it did throw the code for the other side, Bank One. I replaced the pricey A/F sensor, purchased from Lexus dealer and voila, car runs and shifts like a new one. So before you tear into a transmission you must clear those engine codes, because evidently it does go into some kind of limp mode.
I was very tempted to buy an A/F sensor from eBay for $50. They show pictures of the exact correct denso, correct part number, everything, but the car care nut says that Toyota/Lexus only sells it's parts to dealerships. Counterfeits will cause you all kinds of grief. That doesn't mean you can't purchase an original or replacement Denso part elsewhere, but buyer beware. The AF sensor from the dealership has a one-year warranty.
