Transmission Not Shifting on my 2014 Chevy Equinox

I tough truck at my local county fair, and I recently bought a 1998 F-150 to run for the event this year. The truck has been sitting for some time and needs new calipers, however I like to build these without having to throw a bunch of money in. I was wondering if there was any way for me to take the calipers off my 2002 Chevy Astro van that I ran last year and put them onto my '98 f-150. I'm assuming I would have to make a custom mounting plate of some sort? I would like an external opinion before I dive into this if you have any input.

Is your car not shifting gears like it used to? An automatic transmission makes driving much less complicated than the manual gear (stick shift) alternative. But that convenience comes at the price of complexity. When an automatic transmission equipped car won’t shift gears, there could be several potential issues. These issues can range from a simple fix to needing a complete transmission rebuild. Below is technical expertise on “Why is my automatic car not shifting gears?”
Low Transmission Fluid link hidden, please login to view
Your automatic transmission relies on hydraulic fluid pressure to operate. The pump pulls

If the transmission fluid level gets low enough, the pump will be unable to push fluid where it needs to go. Even worse, the pump will pull air into the system, which could lead to a lack of lubrication that damages parts. If you are lucky, your vehicle has a transmission fluid dipstick so you can easily check the fluid level according to the instructions in the owner’s manual. If your vehicle does not have a transmission fluid dipstick but is “
link hidden, please login to view”, that doesn’t prevent you from checking the fluid level. In most cases, the fluid can be checked via a fill plug, but the transmission has to be at a certain temperature and the vehicle must be level. This isn’t an easy task, so it might be best to have your local link hidden, please login to view do it for you. Faulty Shift Solenoid
We just mentioned how an automatic transmission relies on pressurized fluid to operate, but that fluid also needs to be routed to where it is needed. In a modern, electronically controlled automatic transmission, shift solenoids control the flow of transmission fluid. If the shift solenoid is faulty, then the fluid won’t be routed to the desired shift actuator. In older non-electronically controlled transmissions, shifting was controlled by shift valves, but the idea is the same. Shift solenoids can wear out or get stuck, leading to a no-shift condition. Fixing a faulty shift solenoid usually requires removing the transmission fluid pan to access the transmission valve body.
Low Transmission Fluid Pressure
You should be seeing a pattern of how important hydraulic fluid is to the operation of an automatic transmission. If the transmission fluid level is fine, there may still be a problem with the fluid pressure. Low fluid pressure can be caused by a worn out pump, clogged fluid passages or a clogged transmission fluid filter. A lack of shifting car gears due to low fluid pressure usually means it is time for a
link hidden, please login to view. If the problem is with the pump itself, then you are probably looking at a transmission rebuild. Bad Transmission Control Module
Most modern automatic transmissions have an electronic
link hidden, please login to view (TCM). The control module takes input from various sensors, and decides how the transmission should react. Depending on where the control module is mounted, it can lead a very hard life. Extreme temperatures, vibrations, leaking fluids and sometimes even how the circuit board is built can all lead to failures of microchips and other electronic components. If the check engine light is on while you are having shifting problems, the TCM may be the issue. Broken Shift Cable
Each time you drive, the shifter is moved at least twice, once for driving and again for park. That movement adds up over the years. While an automatic transmission doesn’t have the complicated shifting mechanism of a manual transmission, there is usually a physical connection between the shifter and the transmission. Modern
link hidden, please login to view usually have plastic components that can break down over time. There may also be bushings that get worn out. The shift cable itself is usually metal and rarely breaks, but the pieces connecting it to the transmission can possibly fail. Shift Lock Engaged
If the car is not shifting into gear from park, then the issue might be the gear shift interlock. Most modern vehicles have a lockout on the automatic gear shifter that requires the brake pedal to be pressed first. If the brake pedal isn’t pressed, the shifter won’t move. It is possible that the brake pedal sensor doesn’t read that the pedal is pressed, or a break in the shift interlock circuit interrupts the connection. The shift lock can be

Just like how brake pads can wear out, so can the friction materials inside the transmission like the bands. Transmission bands hold certain components in place, while others are allowed to rotate. When this happens, the transmission won’t go into certain gears. Unfortunately worn out bands usually mean a complete transmission overhaul. Material from the worn out bands can make their way into sensitive fluid passages, clogging them or causing accelerated wear
Failed Throttle Sensor
This one may seem odd, but gauging how much throttle input the driver is giving makes a big difference in how the transmission acts. Whether the input is from a
link hidden, please login to view or a cable, if the driver pushes down the gas pedal, the transmission needs to change gears. But if that input isn’t received, the transmission has no idea what the driver wants to do. If the transmission doesn’t know the driver is hitting the gas, it might not shift into the next gear. Even worse, on some older transmissions, if the transmission isn’t linked correctly to the throttle input, severe damage can be done. If your transmission isn’t shifting like it used to, simply head to your local

I've got a 2014 Chevy Equinox with new pluigs, coils, fuel injectors, recent top-engine carbon clean, new AC Delco O2 sensors, and relitively new CAT. Getting a P219A-00 for Fuel trim cyliner balance. Any ideas where to start diagnosing? I saw this online as possible causes:
Leaking or contaminated fuel injectors Low fuel pressure or running out of fuel Leaking evaporative emission (EVAP) canister purge valve Exhaust or intake air system leaks Exhaust gas recirculation (EGR) system Positive crankcase ventilation (PCV) system is leaking or the valve is stuck open Ignition system Incorrectly seated engine oil dipstick, tube or oil fill cap Just curious if anyone has had this issue with a GMC of Chevy and succesfully diagnosed.
