So my fried please help man from Finland

Welcome to the forum.
Have you checked the level of transmission fluid?
It should be checked with the engine running, engine fully warmed up and with the car on a level surface.

Next, check to see if the car's computer has stored any trouble codes.
You may have difficulty finding a shop do this because it requires a special code reader to read the codes.
The 1994 and 1995 computer system is often referred to as OBD 1.5

If it won't go into 4th gear (overdrive) it could be a faulty TPS sensor.

You might want to check your temp gage and see if the engine is up to temp first.

Hello! Next "proplem". My tires. I have those 215/60/16, and they look stupid as hell. So, what kind of wheels are you fit whit your cars? Some 18"?

IIRC, the 2000+ Bonneville wheels can fit onto the 92-99. The 2000+ came with 16" for the SE, 17" for the SLE and SSEI, and 18" for the GXP. Correct me if I am wrong, but I think they would fit onto your car.
