I took my car to a local car wash and then drop my car with them, after i got home i discovered that my gear lever is not engaging up to parking.
I made calls and consultations,thank God i came up with the solution;
I unscrew the two bolt on the lever handle,
removed the handle and engage the lever by pressing on the lever without handle and its engage without itch.
becareful with the spring,though its not a complex mechanism,
Drove the car to a mechanic village then buy another pressing part of the lever handle.
Hope this would help someone someday.
