So just yesterday my cars CEL traction control and Check VSC light came on as I got off the freeway. I noticed at the red light that when I took my foot off of the gas the car didn’t move (it was on D) I had to accelerate for the car to move but I noticed it had lost a lot of power and was super sluggish as I approached a parking spot as I put it in reverse the car wouldn’t move even after I pushed on the gas. It just revs up to about 2000 rpms and won’t go over that. But when it’s on park or neutral it revs over 2000. On D it does the same won’t go past 3000 rpms. I did have a code 3 weeks ago reading “P0761” but it went away now I have no CEL no check vsc or traction lights. Can anyone help or share similar stories on this? The car has 127k miles. Is my transmission done now? Thanks in advance Lexus family ❤️

Reason: New title
After letting the trans cool down overnight, have you attempted to drive it again? Were there any odd noises/smells coming from the engine/trans area yesterday?

no not at all. I actually stopped driving it now I’m scared I’m going to ruin the tranny more I’m gonna open the tranny pan in the bottom and take a look at all the censors make sure nothing is wrong
yeah I’m going to pick up some on Wednesday from the Lexus dealer. Also buying the solenoid that’s “Shift Solenoid C” wich if I’m correct is the SLU one. Hopefully it fixes my problem. I will update the chat if anyone is interested in following it.
Just keep this in mind. The ECU and TCU tell the trans what to do. The also monitor for opens and shorts to all the solenoids.
Back to being told; if the solenoids are told to apply x x x and x solenoids for say first gear and the engine asked to move the vehicle, now the ECU and TCU are looking at the input shaft (turbin input) and comparing it to the output shaft the spins the rear diff.
If the output is moving at the ratio selected by the ecu, all is well. If it is not (timeline unknown), then the ECU points to the last command given. This resolves to select solenoids being put to question.. it does not mean they are defective.
So here is the important part. You must test the solenoids. If they test good, its something else.
The shaft speeds tell the ecu if the command given created the desired effect of moving the vehicle in gear (#), not the solenoids...
Since 1995 I've owned 6 Toyota's and 1 Lexus. None of them ever suffered from engine or transmission failures. My first Toyota was a 1995 Corolla which was a 5 speed MT that was still running when it was traded in at over 200K miles on it (2015), my 1999 Camry (my second Toyota) I sold to a family friend which is nearing 250K and he is still driving (pic attached), a 2002 Toyota Camry LE V6 which hit 100K when I traded it in for a 2006 Toyota Camry SE V6 which has 155K on it and now my daughter is driving, 2004 Toyota Sienna which reached 145K when my wife crashed it into a parked car, a 2013 Toyota Sienna (which replaced the 2004 Sienna my wife totalled) which has nearly 145K on it, and the current 2010 IS350 which has 62K. I'm just knocking on wood that none of these cars ever broke down on me and had/have perfect transmissions. I'm guessing it was changing the trans fluid every 100K...except the Corolla. I don't think I ever changed the MT fluid, or the clutch the entire time I owned it
