The price is also affected a lot depending on what parts and transmission fluid you are using. Valve body replacement cost: $500 to $1000.Shift solenoid pack replacement cost: $300 – 600$.Single shift solenoid replacement cost: $50 – 150$.The prices do not include diagnosis and fluid replacement costs. These are the prices, including parts and labor costs. When you replace a shift solenoid, valve body, or solenoid pack, you should always replace the transmission fluid and filter. You have to replace the whole solenoid pack, or in some cars, even the whole valve body, which is often very expensive. The replacement cost of a shift solenoid replacement depends a lot on what car model and transmission model you have.Īs I mentioned before, in some cars, you can’t replace just one solenoid. Transmission Shift Solenoid Replacement CostĪ single shift solenoid’s replacement cost is between $100 and $350 and a shift solenoid pack costs between $400 and $700, including transmission fluid, filter, parts, and labor work. The shift solenoids are the tubes with yellow, green, and black colors.
In the picture above, you see the shift solenoids located on the valve body. 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. The Transmission shift solenoids are located inside the valve body of your automatic transmission. When it’s time to shift, the transmission control unit sends out power or ground to the required shift solenoid, and it causes the solenoid to open and let the transmission oil flow into the valve body, which then shifts to the next gear. The transmission control module uses all these parameters to calculate when it’s time to shift to the next gear. The transmission control unit is collecting information from the engine, vehicle speed sensors, and other sensors. The transmission shift solenoid’s job is just like it sounds – it basically shifts the gears for you. You can read more about it here: Limp mode. Mostly limp mode causes the transmission to not shift over gear 3, and if there is a bad shift solenoid, it may cause limp mode of your car. Limp mode is a protection function for your engine, and you will notice it mostly because your engine will get an RPM limit of 2500-3000 RPM, and it may also affect your transmission shifting. This can cause hard shifting or shiftings at too low or too high RPM, for example. You may also have intermittent problems with the transmission shift solenoid, which will cause shifting problems.

If this is the case, you can either try to give the shift solenoid external power to release the gear if you know how to do it. If the shift solenoid got damaged while the gear was engaged, it might cause the transmission to be stuck in that gear. This is a big sign that you have transmission shift solenoid problems because you have one or more shift solenoid for each gear, and if one is broken, it will not shift to that gear – instead, jump to the next gear directly. You may also notice that your car may have a problem engaging some gears, and therefore it will skip to the next gear. This applies to both upshifting and downshifting. If the transmission control unit recognizes any shift solenoid problems, it may cause the transmission to shift very slowly. Most cheaper ones can only read the codes from the engine control module. To read the trouble codes from the transmission control module, you need an OBD2 scanner to read generic and enhanced trouble codes.
#F4a42 transmission fluid code#
If this light is on, it might be a stored trouble code related to a bad transmission shift solenoid. Some cars do also have a separate transmission warning light. This code basically tells you that there is a problem with the transmission control, and more trouble codes will be found in the transmission control module. Mostly it lightens up, and you will see a P0700 Trouble code. The check engine light will light up even when there is a problem with the transmission. The first sign you will notice of all bad shift solenoid symptoms is probably the check engine light.
