How to replace an FWD automatic transmission?

But, as a vehicle owner, you should also know the exact process of replacing an FWD automatic transmission.
Here is how to replace an FWD automatic transmission:
1. Loosen the front axle nuts
The process begins by loosening the two front axle nuts. You can use a spindle nut and a breaker bar to do this. Do not remove the axle nuts, just loosen them.
In addition, also loosen the front wheel nuts. You may even need to place a drain pan under the transmission. The goal is to drain the fluid as mentioned for your car.
2. Remove the battery
The battery and air intake system might block your access, remove them. Disconnect the battery, even if you still have space around it. So, the second step is to remove the battery from your vehicle.
3. Lift the vehicle
The next step is to block the rear wheel and lift the vehicle using the jack. Now, place the jack stands under the chassis behind the front wheels and lower the car onto the stands.
Now remove the wheels and axle nuts. Place the jack under the transmission to support it before preparing the lifting strap for the job.
4. Remove the starter bolts
Support both the transmission and the engine, remove the starter bolts and even the transmission-to-engine bolts. Use a universal joint socket to reach these bolts.
5. Disconnect the transmission
Now, you will need to disconnect the transmission cooling lines. Let them drain into a container before removing the dipstick, shift lever cable, and other electrical wires connected to the transmission.
6. Remove the axles
This step involves removing the front axles, the lower bell housing cover plate, and the torque converter bolts using a screwdriver.
It is best to measure the depth of the torque converter residing inside the transmission case. You might need this later to put things back in place.
7. Attach the lifting strap
All that remains is to attach the lifting strap around the transmission. Now, remove the transmission and engine mounts in addition to the mounting bolts. Disconnect the transmission from the engine.
8. Focus on the new transmission
Now, you will need to focus on the new transmission. Properly place the new torque converter. Keep rotating it while pushing to set it in place.
Now check the depth measurements you took earlier and initially set the transmission. Make sure to place it correctly; once you have done so, compare the old and new transmission.
9. Lift the replacement transmission
The next step is to properly put the replacement transmission back in place. When aligning the transmission to the engine, make sure you have an alignment pin that helps provide the first point of contact before installing the transmission-to-engine bolts. Refer to your repair manual for tightening all bolts.
10. Reinstall the torque converter bolts
Now follow the reverse steps of disassembly. All bolts and nuts will be tightened properly. There should be no loose nuts or bolts.
This is another step to follow when you want to know how to replace an FWD automatic transmission.
11. Install the axle nuts
This step will involve installing the axle nuts. Mount the tires and tighten the wheel nuts. Remember that there must be stable contact with the wheels.
Now, lift the vehicle off the jack stands. Tighten the axle and lower the jack to remove it completely.
12. Fill the transmission with fluid
When you want to know how to replace the FWD automatic transmission, it is best to choose a high-quality fluid for your vehicle. Choose the best quality transmission fluid to fill the transmission.
To find out which fluid is best for your vehicle, you will need to refer to your vehicle’s manual. So, when filling the transmission, start by running the engine and let the transmission warm up.
Change the gears and let it shift through each gear to check that everything is working normally. Check the fluid level and avoid overfilling the transmission. Leaking fluid can cause damage.
