LEXUS ES300 TRANSMISSION by lburnett005

1993 LEXUS ES300-OVERHEATED-REPLACED THERMOSTAT. DID NOT REGISTER OVERHEATING BUT WAS FORCING FLUID INTO OVERFLOW & OUT. REPLACED BOTH PRESSURE CAPS. SEEMED TO RUN FINE. DROVE 100 MILES TO INDIANAPOLIS & HOSE BETWEEN RADIATOR & SECOND CAP SPLIT-REPLACED ALSO REPLACED SECOND PRESSURE CAP AGAIN. ON THE WAY HOME NEXT DAY, RPMS DROPPED WHILE ON HIGHWAY WITHOUT WARNING AND WOULD NOT GO INTO GEAR. TEMP GAUGE WAS NORMAL. TURNED, OFF CAR & RESTARTED--THEN WHEN REACHED NORMAL OPERATING TEMP--NO TRANSMISSION AGAIN. TURNED CAR OFF AND IMMEDIATELY RESTARTED, TRANSMISSION WORKED AGAIN, SMOOTHLY TIL REACHING OPERATING TEMP AGAIN. WHEN A TRANSMISSION GOES OUT, ISN'T IT JUST OUT? HELP?

Sounds as if you engine is "struggling" to run in idle mode. That might result in low engine vacuum for brake power BOOST.
 
Have someone check the idle air bypass system and if that's okay then suspect a burned intake valve.
 
With a '99 I would vote for a clogged idle air bypass port/channel. Once it's cleaned out disconnect the battery for 10 minutes or so to force the engine ECU to more quickly learn/adjust to the new free flowing idle air bypass.

You MAY have a manifold gasket leak that is allowing fuel combustion pressures into the coolant system.
 
"..both pressure caps.."
 
Only the cap on the radiator should be of the pressure type.
 
ATF cooling loop within the radiator leaking..??
 
Did you by chance initially type this post on a 33ASR teletype..??

2005 ES330 has the same transmission probs by firbird

I have a 2005 Lexus ES330 and have had it since day 1, and it has always had a hesitation and "kicking"" into gear issue, more pronounced now that the car is at 80,000 miles.
 
I'm overwhelmed by the amount of information and number of Lexus owners that have this issue and no resolution has been found.
 
I think we need to organize a grass-roots campaign and go to the top if need be to get this issue out in the open and addressed. Maybe we should enlist the media. Anyone have any ideas/contacts?

es350 trans shutter by jlatko

I just read the complaint about an ES and the "Rumble Strip" sensation at certain speeds. This is NOT! normal. If other makes do the same thing, then they also have faulty transmissions. I noticed that problem on my 2008 ES350 almost immediately after purchasing it. It happened very randomly, which can be a nightmare to convey to a technician. Fortunately, my dealership {HIghland Park Lexus) never even questioned me about it. They were aware of problems with this transmission and immediately recommended a new one. 20,000 miles later the trans is working fine and I have never had another rumbling incident. It seems like other Lexus dealerships need to take a lesson from Highland Park in customer satisfaction. The main reason why I would still consider buying a 5th Lexus is the way they handled that situation. Remember, if you suspect something is not the way it should be, chances are that something is wrong. Don't let some confusing high tech explanation cloud the issue. It's not rocket science.

Lexus publishes TSIB=technical service information bulletins.The problem with your car was a torque converter issue which happens at certain rpms.If you had gone to any Lexus dealer they would have had the info to have helped you.

You should go to your dealership and have the computer reflashed.The programming in the transmission needs to be updated.

If the transmission has been reflashed I would go back to the dealer and tell them your still having transmission issues.They have to replace the transaxle if they refuse.I would call Lexus the number will be in your owners manual or the dealership can provide it.05 ES330 is under warranty under the Lexus 7yrs/70,000 mile powertrain warranty.

The problems the ES350 are very minor as in a nuisance.The wind noise can be repaired without an issue.The knock noise from engine is normal noise from a timing chain driven vehicle and it only happens at cold start.It's a little rattle cause of no oil in the starting process on the chain.All transmission issues are small and can be handled usually in your first visit to the dealership.The interior rattle noise can also be taken care of in one visit.You have to think of it this way it all depends where in the country your at can affect your vehicle and Lexus is aware of the issue and trying everything to provide repairs.I am a Lexus Tech and trust me all of our customers love their Lexus.

Thank you for your message. Can this also cause the battery to die. I have not driven my car for 1 month and the battery was dead. My husband jump started the car. It seems OK now. Notice too that I have to press my remote key several times and hard to lock and unlock the car.
