today when i drove from shop to house my car went into rev as normal and on my way home the tranny had seemed like it was slipping a bit. Within a mile it had become worse one more mile to home and by the time i got there and needed to back up i could not find reverse. Every gear seemed to be drive. Over and over I tried to shift. No neutral, no reverse, no park. Only drive. Went under to look and shift through gears. linkage seems fine. It is clicking into every position as normal. Still nothing but drive. It also seemed to be bogging the car down. It wouldnt even idle properly. In park it only made the notion to go forward but did not move. Prior to this everything was working perfectly fine. The car (65 plymouth belvedere 2)had sat for about 4 days. the 318 and 727 are not origional.
