Of course, try the manual selections for the gears, as available, such a "1", "2", L, and so forth. If those still work, that may help you to at least move the car. No operation in drive could be due to low fluid level, a shift cable adjustment problem, a hydraulic leak (internal), a broken band, a faulty solenoid, a faulty valve body, a clutch pack piston leak, and so forth. With such a "total" failure (versus an intermittent problem) the good news is the diagnostic is more straightforward. Some of the causes just identified can be fixed without removing the transmission. However, if the clutch pack is bad or a band is broken, the transmission has to be removed from the car and usually the optimal strategy, for long run use of the car, is to thoroughly rebuild the transmission if it is already off the car. Transmissions are actually easier to work on, and repair, in many, many respects, compared to engines, so you needn’t worry as what you have will be fixable. If you want to schedule a diagnostic of this issue, please use YourMechanic’s shift failure diagnostic service page. If you request that diagnostic, the responding certified mechanic will get the underlying issue identified and let you know of your repair options.

How to Identify and Fix Common car Problems ?

Your Lexus won`t go in reverse for several reasons ranging from a brake light switch, low transmission fluid level, and even a dead battery.
Just as you learned what happens with low transmission fluid, dirty fluid, or a clogged filter can cause similar transmission troubles and create a car that won`t back up in reverse. Improper lubrication from old fluid or debris in contaminated fluid will affect how the transmission shifts into reverse or other gear.
If your RX 350 has slow acceleration and does not give enough power, it is most likely due to a problem with the engine itself. Many common causes of engine problems, such as worn spark plugs or a dirty air filter, can cause the engine to run slowly. Some customers think premium gas will help.
How Long Will the 2009 Lexus RX Last? A well-maintained 2009 Lexus RX can easily last over 300,000 miles, which is twice as long as competitors like the Mercedes M-Class. Regular annual maintenance costs are good for a luxury SUV, at only $527 per year, according to Repair Pal.
On a manual transmission vehicle, misadjusted shift linkage and damaged or stretched shift cables can keep the reverse gearset from locking when moving the shifter. With an automatic transmission, bad cables or misadjusted linkage can make the shift indicator point to Reverse when you`re actually in Neutral.
The type of symptoms you are describing (with the reverse problems) are typically caused by obstruction of debris in the hydraulic lines of the transmission – so a flush and filter change is likely going to clear up your issue.
Problems Reversing – One common problem that can happen with a clogged filter is difficulty moving in reverse. The lack of fluid flowing through the transmission can cause the reverse gear to lock. This may prevent the car from going in reverse altogether, or it may cause it to hesitate before launching into reverse.
Culprits include a dirty fuel filter, clogged fuel tank strainer, clogged or failing fuel injectors, or a defective fuel pump. On most vehicles replacing the fuel filter is a DIY operation.
An indication that a vehicle is not receiving the right mixture of air and fuel is if the vehicle jerks or surges forward at high speed. Several components of the fuel or air intake system could cause this jerking or surging sensation to happen. Issues within these systems can also cause fuel economy to worsen.
One of the most important reasons for a car struggling to accelerate is clogged or dirty car parts. The reason is that they cause the engine to lose power. We can sort significant car parts affecting acceleration as air filters, mass air flow sensor, exhaust system, and fuel system.
They changed to the chains in the 07 RX350s and the advantage to the 09 model I had been considering had a timing chain and there was no scheduled maintenance/mileage to work on the chain (unlike the timing belts which need replacing every 100k miles and are quite expensive) and no need to do any work on the chain or …
The best RX models most likely to yield a great experience are those from 2014 and 2018. These vehicle have fewer reported problems than other years. Costing $10,000 less than a 2020 model and likely still having factory coverage, the 2018 Lexus RX is the best year of the vehicle to have sitting in your driveway.
But if the solenoid malfunctions mechanically, no reverse or delayed and slipping reverse may occur.
If when you put your vehicle into gear and it won`t move, this may be a problem with low transmission fluid due to a leak, the shifter, shifter cable, or it could even be a problem in the valve body of your automatic transmission.
A failing transmission position sensor may no longer send the right signals to the Powertrain Control Module, or PCM. Without signals from the position sensor, the PCM will no longer know when to shift the transmission`s gears out of park into a moving gear. Transmission shifts into the wrong gear.
The transmission position sensor is usually screwed onto the side of your car`s transmission. As you move the automatic gear selector from park/neutral to drive or reverse, it detects the changes. It then enables and disables the connection to the starter motor circuit, affecting your car`s ability to start.
A transmission rebuild cost averages $3,000. In comparison, a transmission replacement cost averages $6,500. Finally, a transmission repair will cost approximately $800. Since these prices can vary significantly, you should talk to a local auto shop to determine the exact transmission repair cost for your vehicle.
However, a defective speed sensor is viable by an illuminated warning light on the dashboard, signalling that it`s time to repair or replace the speed sensor. These are the major causes that hamper the transmission system, due to which the car won`t go in reverse sometimes.
If your Lexus is having trouble accelerating, it could be a sign that there`s an issue with the gas tank. If the tank isn`t able to hold enough gas, or if the gas isn`t flowing properly, it can cause the car to have difficulty accelerating. Also, check the fuel line to see if there are any blockages.
Worn Transmission Fluid (Automatic Transmission)
Over time, the transmission fluid gathers dirt and grime. This can cause the engine to run roughly, stall or fail to accelerate when you press down on the gas pedal. You may need to have a transmission fluid change before more damage is done.
If you`re driving at freeway speeds and notice your engine sputter or jerk, you may have a failing fuel pump. This problem is caused when the fuel pump can`t deliver a smooth flow of fuel to the engine; periodically, your engine receives only air when it was expecting to receive fuel.
An engine that is hesitating to accelerate is most likely dealing with a fuel/air mixture that is too lean. Engine`s that are running inefficiently will begin to show signs like hesitation which will only become worse over time.
If a spark plug or multiple spark plugs are faulty, they will have trouble creating the spark that causes the ignition process in your vehicle. This results in your vehicle having trouble starting, hesitating or having issues with accelerating properly.
