Before having the engine replaced the car shift perfectly fine but now after having a new engine in the car won't shift into second unless you , work your foot on the gas & pull it to low gear the rpm be sounding like it's going up I don't have an rpm gage in my car so I don't keep flooring it when I hear the the Reving of the engine the transmission fuild be leaking . I just need a answer to these problems do I need new trans or rebuild or would it be the linkage ?? Let me know
My car has an automatic transmission.

Over time, dirt, debris and other tiny particles can accumulate in the transmission fluid, affecting its fluid properties. This can cause the vehicle to die when you shift into drive or reverse, allow a loss of power, transmission slip, rough shifts or even prevent the vehicle from shifting into gear at all.
Shifting delays are often caused by many things but most commonly due to poor maintenance or high mileage. Transmission fluid, in addition to acting as a coolant, keeps internal seals lubricated to help prevent hardening or wearing out.
Check to see if the brakes are applied and see if the master cylinder is full of brake fluid. If you need further assistance with your vehicle not moving when putting the transmission in drive or reverse, then seek out a professional, such as one from Your Mechanic, to help you.
This is often times a sign of low transmission fluid or a faulty transmission control solenoid. As you know, automatic transmissions use pressurized hydraulic fluid to change gears.
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.
The easiest way to remove lag is by installing a device on your gas pedal called a throttle response controller. Throttle Response Controllers are blue tooth controlled, inexpensive, and make a big difference in immediate gas pedal response.
Clean or replace your vehicle`s air filter when your acceleration is acting sluggish. Put in new spark plugs when they go bad if your engine misfires and hesitates. Replace your vehicle`s fuel filter when there`s a delayed response when you accelerate.
Transmission Control Module (TCM) or Powertrain Control Module (PCM) All automatic transmissions use a control module to regulate speed, gear changes, and clutch engagement. The TCM makes decisions based on the information it receives from the engine, making it the key to shifting gears and changing the speed.
Transmission Shift Solenoid Location
The Transmission shift solenoids are located inside the valve body of your automatic transmission. They are integrated into the valve body, and on some car models, you can see them without removing the valve body, while on others, you have to remove the valve body to reach them.
In general, the torque converter includes components like a pump, a stator, and a turbine. Any one of these could become faulty, which can cause slipping when your transmission shifts gears. It can also keep the transmission from successfully shifting at all.
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. If a shift solenoid goes bad you can experience very similar symptoms.
The issue is the clutch is slipping. When the transmission is in second gear, the power train is in an in between gear ratio and will cause the vehicle to have a loss of power during acceleration. I recommend seeking out a professional, such as one from Your Mechanic, to help you diagnose your clutch.
The most common cause of a stuck solenoid is the failure to replace your transmission fluid when you should. Over time, small bits of metal and other debris will get into the fluid (if you`ve ever seen black transmission fluid, this is what causes it). And this is what leads a solenoid to become blocked.
The cost to reprogram a transmission ranges between $75 and $250. Most of the time, you can get this done at your local dealership, but you can also trust a local repair shop, like My Transmission Experts, to get the job done.
Why does my car not accelerate when I push the gas? A car not accelerating properly can be caused by a number of things. It could be due to the throttle body, gas tank, spark plugs, or the ECU. It could also be because you have a dirty air filter or a clogged fuel filter.
Clogged Fuel Filter When you press down the accelerator pedal and get minimal output, it could mean you have a problem with your fuel system. The most probable issue is a clogged fuel filter. Your fuel filter works to ensure that dirt and debris do not get into the fuel system.
If your accelerator were to stick it would most likely be caused by a floor mat or other object getting jammed under the gas pedal. This could obviously be avoided by keeping your vehicle clear of clutter and making sure floor mats are properly fixed in place.
Delayed engagement could be due to a variety of reasons from something as minor as a low level of transmission fluid, infrequent fluid replacement, or a more serious issue like failing transmission solenoids.
When a throttle body is not functioning correctly, you`ll usually notice a distinctly poor or very low idle. If the problem is really severe, you might even begin stalling when coming to a stop or when the throttle is quickly pressed.
Rough starts, hesitation and poor acceleration are all common symptoms of a bad spark plug. 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.
One main reason why the automatic transmission in your car may not be shifting smoothly is the ECM is going bad. It is best to get this checked out by an experienced auto mechanic technician who understands the electrical system. Other indicators include bad connections within, or worn out sensors and faulty solenoids.
