If you have a small issue with the lever door of the automatic transmission, it can be fixed in the following way.
I didn't photograph the disassembly and assembly process much as everything is quite clear. The only thing I had to do was cut two wires on the overdrive button, clean them up, attach a separate long wire to pull them back with, and pull out the entire lever along with the wires. A small wire remains inside the black cover.

That's what the problem was
I cut a piece of paper from an office folder to fit the old lever door
The hole was made with a thin soldering iron (I have a soldering station), then I trimmed it with a scalpel. Whoever cuts this should not face any issues. ATTENTION: The hole on the old lever door is slightly larger, as you can see that it's damaged by the lever itself, so make the hole based directly on the lever and not the old door.
I cut off the marker from the old lever indicating which gear is selected.
Old and new
First I glued the marker with super glue, but the plastic of the folder was too greasy for the glue to stick. So I had to gently solder it.
No matter how many times I tried gluing-it didn't work
Well, that's better now
Putting everything back together, pulling wires through
As good as new!!!
For those who don't have this lever door at all... here are the dimensions...
