Hi, My Lexus GS300 won't shift any further than 3rd gear. I've got 2 error codes P2714 - Pressure Control Solenoid ‘D’ Performance or Stuck Off P0761 - Shift Solenoid ‘C’ Performance or Stuck Off when I clear codes using Techstream car will go into 4/5/6 gear but after a 5-10 minutes codes come back and it goes into limp mode. I already changed all Solenoids and oil - no luck Next step I changed gearbox and oil - no luck Lastly I replaced ECU - no luck Do you guys have any suggestions ? what else could I check in this case ? It really drive me nuts...

Hi, Did any of you guys managed to replace automatic transmission in Lexus GS300 MK3 ? Mine is 2005 and I was thinking to do that job next weekend but didn't find any DYI tutorial. Can any of you share some tips/trick to accomplish it successfully ? Any help will be appreciated. Now only first 3 gears are working, replaced all solenoids and new oil and no luck. Thanks Bart

Valentin, have you managed to reaplace your transmission ? do you know what was the oil capacity ?

GS3uk have you managed to replace your gearbox ? what was the hardest part to do it ? are you able to write up short tutorial ? I will be doing it next weekend thanks

Hi all, many thanks for you replies. Camshaft position sensor B has been replaced with no good results, also tested all ignition coils and they work good. Checked all connectors and they were ok as well. I know good mechanic would just replace parts one buy one a do a guessing game but I even called Japex who do repair loads of japanese cars and they said if its timing chain they dont want to do it an sent me back to lexus but they say to repair all timing kit will cost as much as this car is worth so no worth doing it. Steven it was just this code as i used techstream to see any other codes. May call Toyotec and see what he says. Used my endoscope and suspect stretch/worn timing chain on VVT sprocket as it looks very loose or tensioner went bad The place where i use my endoscope is highligthed in yellow on one of the pictures. Really dont know what to do, may sell is as it is or do breaking and sell parts only got also a video when engine is running so if any of you is good with diagnostics you can see the stats while the engine is running. its visible on video that misfire count is rising while im reving up engine. https://youtu.be/UokVEEM4eo4

Hi, Im wondering if someone had a similar problem knows what could be the reason for the sudden misfiring of the engine in lexus gs450h. The failure occurred suddenly at a speed of about 50mph the engine suddenly lost power and began to work unevenly as if was misfiring. It sounds like a diesel now... The car was towed to a mechanic, hooked up techstream and error P3090 Camshaft Position Sensor 'B' Circuit Bank 2 popped up. The mechanic said that maybe it was the spark plugs and not the sensor and replaced all the plugs, but the problem remained. The sensor will arrive after Christmas and will also be replaced, but I do not know what to do next? The mechanic said that it could be a pulled timing chain or jumped one tooth and he doesn't know really lol Has anyone of you had a similar problem ? the car starts engine without eny problem but it seems as if it is not running on all cylinders. Mileage is 168k. What else should be checked to try to remove this fault ? Anyone knows any good Lexus mechanics in Hertfordshire ? I am attaching a video of the engine running

have you managed to sort out your engine ?
