The main driving symptoms that you will notice with the symptoms of a bad transmission control solenoid is that there could be delayed gear shifting, you can’t downshift and your engine will continue to rev, your transmission will be stuck in the neutral position, and the shifting of gears becomes very rough and choppy
A problem with one or more of the solenoids can cause a lack of pressure, resulting in hard, soft or delayed shifts. Transmission won’t shift gears: A faulty shift solenoid can prevent fluid pressure from activating the appropriate gear. As a result, the transmission may not shift gears or it may get stuck in neutral.
In most cases, solenoids are located inside of the oil pan, connected to the valve body. Depending on what you drive, the technician may be able to replace just the failed shift solenoid .
Cleaning the Solenoid Valves. Spray MAF sensor cleaner through each filter screen on each solenoid valve. It is designed to remove oil, dirt, fibers, dust, and other debris to clean and unclog the parts. You can purchase MAF sensor cleaner online or at an auto parts shop.
What Repairs Will Fix P0752? Changing the transmission fluid and filter. Replace faulty solenoid . Repair or replace a faulty transmission pump. Repair or replace defective transmission valve body. Perform transmission flush to clean passages. Cleaning corrosion from connectors. Repairing or replacing wiring.
The short answer is that, yes, you can usually drive a car with a bad shift solenoid . Granted, it might not shift past a particular gear, but you should be able to drive it for a short period of time without causing any serious damage. If it did, then you ‘ll know right away because the car won’t move.
If you suspect a bad shift solenoid , it should be tested. Raise up the vehicle with a jack and place jacks stands at all four corners to support it. Remove the bolts that are securing the transmission oil pan with a ratchet set and slide out the pan. Find the two plugs just above the shift solenoid . Unplug one.
Associated Systems. Most modern vehicles have some sort of transmission control module that monitors the transmission through various sensors, such as the shift -position sensor and the transmission speed sensor. Additionally, the TCM and solenoid wiring are protected by fuses .

Will a Bad Shift Solenoid Throw a Code ? Ignoring a warning light or code being thrown by a faulty transmission shift solenoid can lead to serious problems, such as running your vehicle in the wrong gear for your speed and conditions. This can then lead to your transmission overheating and breaking down.
The solenoid lends itself to repair just like any other component, and savings can be realized by doing so. Place the vehicle in neutral or park with the emergency brake set. Slide under the vehicle and remove the main starter wire and the two (or three) ignition wires on the back of the solenoid .
Both the A and B shift solenoids are the same part number.
Automatic transmissions that shift hard , jerk or shake during a shift change may mean your transmission fluid needs changed or fluid level is low. In manual transmission vehicles, abnormal gear shifts could indicate damaged gear synchros, worn clutches or other, more severe issues.
How to Replace a Transmission Solenoid Vs. Rebuilding It Drive your vehicle to an automotive parts store. Purchase a replacement solenoid from the automotive parts store. Park your vehicle and turn off the ignition. Crawl underneath the hood area of the vehicle. Remove the bolts that secure the fluid compartment to the transmission using a wrench-and-socket set.
Shift solenoids have a spring loaded plunger wrapped with a coil of wire. When the shift solenoid is activated, the plunger will open certain valves in the valve body to allow transmission fluid to enter. That puts pressure on the clutches and bands that cause the transmission to actually shift gears.
