I think many people wanted to drive a Rivett with an automatic transmission, just like me. But when loading a save, the automatic transmission behaves incorrectly, making it impossible to drive. I finally managed to get the automatic transmission to behave correctly.

Installation:

Unzip the archive with the save.
Copy the files to: C:\Users\[Username]\AppData\LocalLow\Amistech\My Winter Car\Saves.
Launch the game and load the save.
How to start the car:

Get in the car, insert the keys.
Turn the ignition on and crank the starter until it reaches the crank position (no more than necessary).
If the voltage drops to 12V, rev it up slightly.
It is recommended to warm up the garage (close the gate, turn on the heaters).

PIN code from the card - 1234.
