2010 Ford Transit Connect Error Codes 0736, 0731, 0733, 0734, 1790, and 0792 - Diagnosis and Fix

I'm seeking help with my 2010 Ford Transit Connect that has been displaying multiple error codes: 0736, 0731, 0733, 0734, 1790, and 0792. Initially, the vehicle showed only error code 0792, which the scanner indicated was related to an incorrect gear ratio and an intermediate speed sensor issue. I replaced one of the three intermediate speed sensors (located on top or beneath the driver's side tire), assuming it was the faulty component. However, after the replacement, the vehicle performance deteriorated significantly, and now all these error codes are appearing simultaneously. As a single mother with limited access to repair resources, I urgently need guidance on how to properly diagnose and resolve this issue. Any advice or step-by-step troubleshooting would be greatly appreciated.
