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, last few days, when I started up my car, I heard the noise sound like from the transmission area, but the car worked fine. I didn't realize that was a warning sign. Today, when I drove it the RPM was up to 3000 but the car didn't move as it should, It felt like slipping. Turn off the engine and started up again, then I could drive up to 40 mph with 2nd gear. A few years back, I had a similar problem and it was a dirty filter and worked after I changed the fluid. Since it's been just 10k from my previous flush, I think clogging up filter now does not make sense. Do you have any experience about this? I do not think the fluid is low since it covers the hot mark when the engine is at hot. I searched for transmission pump but couldn't find anything. Nearest dealership is about 2 hours away so taking it there is out of option. Do you think AAMCO can handle Lexus LS400? Can Toyota dealer repair it? For Lexus transmission, I do not like to take it to Mr. "fix any car" mechanic
I have a 2002 rx300 fwd, and I know I am late to the game, but like just about everyone that has posted here, I also had the same problem and (thanks to many of you) the same solution. I had the filter replaced, system drained, new ATF added and everything worked out great (especially saving the 5k on a new transmission). This was about 2000 miles ago (135k miles on the car).
This past weekend I drove to DC from Pittsburgh and back with no problems what-so-ever, until I pulled onto my street and all of a sudden the car jerked and the rpms shot way up but the car didn't really move (I think it would go about 25pmh while at 5000rpms), like it did just before it quit completely and before I had the filter/fluid replaced. Thinking that maybe the filter was clogged again I replaced filter/fluid a second time. I should note that the fluid looked like it the day I put it in - still very red and hardly anything in the filter.
Now here is the new issue - when you put the car into drive or reverse there is (what my mechanic calls) a delayed engagement. That is to say, after a few seconds the car will finally move. If you push too hard on the accelerator the car will jerk hard and then engage. If you are very easy on the accelerator, if doesn't jerk, but still takes time to engage. Once the car is moving, however, everything is seemingly great. I took it for a test drive on the highway, once I merged into traffic and had the car going about 35mpg it shifted very smoothly. Its just went it idles that it drops out of gear and then has the delayed engagement. My mechanic suggested that it might be the gear pump in the transmission itself, that is failing, and that it is not building up enough pressure when first put into D or R. Any thoughts or guidance here would be greatly appreciated.
