I did a transmission filter and fluid change on my vehicle listed above 4 door and noticed shift solenoid b was broken. I replaced it with a new one from the hardware store but when I went for the test drive, first and fourth gears were gone. I put an obd2 code reader on it and received error code P0756 shift solenoid b stuck off. I'm rather stumped at this point please help? Also there's no blown fuses.

Unfortunately this is not a blown fuse. I attached the testing that we need to run through in order to determine what the issue is.

Review this material attached and let me know if you have questions. Thanks
