You May Have a Faulty Transmission
When your car`s critical components that control the transmission are acting up you can very likely only be able to drive in reverse. This could likely be due to a faulty computer that controls the transmission, a faulty transmission solenoid, or another issue with your transmission.
This may be a sign of low transmission fluid or a faulty transmission control solenoid. As you know, automatic transmissions use pressurized hydraulic fluid to change gears.
Transmission won`t engage or stay in gear
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.
The linkage between the shifter and the transmission range selector may be binding or broken and not allowing a full range of movement at the transmission. The linkage connects to the transmission under the vehicle so it must be lifted or the mechanic may have to crawl under to check out the linkage.
Turn off your vehicle`s ignition and wait patiently for 5 to 10 seconds. Start the engine and allow it to idle for several seconds. Switch off the ignition and wait patiently for another 30 to 40 seconds. Repeat these steps 2 to 3 times in order to reset your vehicle`s transmission control module.
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.
The maximum recommended speed in 2nd gear is: 69 mph (110 km/h). This position is to be used when stronger engine braking is needed.
Can i shift my automatic transmission from D to 3, 2 or 1 without stopping the car? Yes you can. It`s handy for towing and steep hills. Assuming you`re talking about an automatic/standard, all it does is limit the highest gear it`ll use.
Your vehicle could have dirty fuel injectors, a damaged fuel pump, a blocked catalytic converter, a faulty mass airflow sensor, broken spark plugs, or even an accumulation of moisture.
Any time a battery is disconnected, or in your case a transmission is replaced, it can take up to 90 days for the engine and transmission computer to relearn your driving habits. It`s normal for an automatic transmission not to shift into higher gears until the engine coolant temperature is at a specified temperature.
A surefire sign of a failing torque converter is when the vehicle won`t shift into a specific gear at all. If you can`t get it to go into reverse or forward drive won`t engage, then it`s probably something wrong with your torque converter.
But if the solenoid malfunctions mechanically, no reverse or delayed and slipping reverse may occur.
An ECM is an Engine Control Module, which can also be seen as ECU or Engine Control Unit. Its main responsibility is to make sure that your automobile functions to its fullest potential, with maximum performance levels. It does so by keeping track of or reading all of the sensors in the engine bay.
Second gear works just like the first gear, except you should only enter second gear once you`re done with the first. Good scenarios for second gear are when you`re on a slippery road and need to lower your speed for your tyres to get a better grip on the surface. You can also use 2 for engine braking downhill.
“2 (D2)” (Second Gear):
Use this position for hill climbing, engine braking on downhill grades, or starting on slippery roads.
Automatic: Every 60,000 to 100,000 miles
If you drive manual, most manufacturers will recommend changing your transmission fluid every 30,000 to 60,000 miles. If you have automatic, you can typically boost that range up to 60,000 to 100,000 miles. There`s no harm in changing your fluid early.
Insert long funnel into automatic transmission fluid dipstick hole. Carefully add automatic transmission fluid in small increments and recheck level each time until fluid level reaches “warm” line. CAUTION: DO NOT OVERFILL OR SPILL AUTOMATIC TRANSMISSION FLUID ON HOT ENGINE PARTS!
This issue may be caused by a couple of different things. A gasket near the transmission filter where it mounts to the valve body could be leaking causing the hydraulics within the transmission not to engage second gear properly. On the other hand, a shift solenoid may also be at fault.
Maintain Proper Transmission Fluid Levels
The #1 cause of transmission failure is low fluid, which causes overheating. In automatic transmissions, it causes delayed engagement, harsh shifts, and slippage.
Transmission Range Sensor (TR)/ Transmission Position Sensor
The PCM uses this information to control which gears of the transmission to enable or disable. When the TR sensor fails it can cause wrong gear starts, no upshifts, or what feels like a falling-out-of-gear condition.
Shifting is rough.
This common symptom of a failing transmission is easily noticed. If your transmission is having a tough time shifting into other gears, or refusing to do so completely, you`ve got a bad transmission and it`s time to schedule an appointment at your local dealership.
It won`t necessarily damage either your engine or transmission. You should realize it will cause more engine/tranny wear due to higher than normal RPM usage. You`ll also experience lower fuel mileage. Also, a possibility of overheating if the cooling system is not in top shape.
In “D” mode, the car may even shift into higher gears to warm up the engine faster in cold weather. When “D3” is selected, the car will automatically shift between the first three gears, but will not shift to a higher gear.

My car drives in 1 and 2 but does not drive in d.. it does go into reverse Chevy Tahoe
ANSWER : Hello – most likely problem for this "no go" condition is a failure of the forward sprag (a one-way clutch) in the transmission. I would recommend a transmission inspection by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
Car drives in 1 and 2 also reverse but car feels like its in neuturl when its on D
ANSWER : The final drive forward clutches are worn out or the apply piston seals are bad. Either way the transmission needs to be overhauled or replaced.
My car want go drive but will go in reverse and shift in 1 or2 and drive some, so what could it be.
ANSWER : This is an internal transmission problem with the valve body or the 1-2 sprag unit binding internally in the transmission. Have a qualified transmission diagnose the problem firsthand to pinpoint what is going on. The mechanic may have to do a pressure test to isolate the cause of the shift concern.
I just got a new transmission put in my car and it drives and reverse but won’t go up hill.
ANSWER : This may be a sign of a faulty transmission control solenoid. As you know, automatic transmissions use pressurized hydraulic fluid to change gears. Every time a gear change is required, the car’s computer activates a transmission solenoid, which directs transmission fluid into the valve body to engage the correct gear. When this is faulty or not working properly, this can cause a delay in gear shifting or in some cases cause the car to not shift at all. I would recommend having an expert from YourMechanic come to your location to take the car for a test drive to more specifically determine the cause for this.
The engine stalls when I put the car in reverse, but if I go past reverse into drive there is not an issue.
ANSWER : Hi there. Usually when you shift into reverse and engage the brake it will cause the engine RPM to drop; as it’s creating a load against the transmission and the engine. If the engine stalls, it may be caused by a faulty idle control valve, bad O2 sensors, or clogged fuel injectors.
In regards to the "pan", we’re not sure what you are referring, so it may be a good idea to contact one of our local professional mechanics to complete a battery inspection to determine what’s going on with your 2010 Ford Focus.
Is my transmission going in my car?
ANSWER : You need to have the computer tested for codes and the engine checked for a vacuum leak to the brake booster. This would account for the high idle and lack of brake power assist. The most likely cause is that the brake booster hose came out when you were working on the engine to replace the O2 sensor. A certified mechanic could help you diagnose your acceleration issue and the other symptoms you are describing to find the right fix.
Started Three days a go. When I drive the car it doesn’t go in to gears but shows AT.
ANSWER : This kind of reaction is often a sign of low transmission fluid or a faulty transmission control solenoid. As you know, automatic transmissions use pressurized hydraulic fluid to change gears. Every time a gear change is required, the car’s computer activates a transmission solenoid, which directs transmission fluid into the valve body to engage the correct gear. When this is faulty or not working properly, this can cause a delay in gear shifting or in some cases cause the car to not shift at all. This type of problem is amplified any time the transmission is low on fluid creating a drop in hydraulic pressure. I would recommend having a professional from YourMechanic come to your location to diagnose and inspect your vehicle.
Replaced alternator on car 2 times each time shows it’s charging 14v let car run for a little bit then test drive and car voltage
ANSWER : There are reports that the replacement alternators will not communicate with the engine computer and will not charge correctly. I recommend using only the manufacturer approved replacement part. It can be new or remanufactured but approved for use in the vehicle. Some lower cost alternators on the aftermarket will have charging problems since they will not communicate with the ECM on the vehicle and will stop charging.
