Check the linkages between gear shift and Box could be loose. If these are OK get a transmission service by a good Auto Transmission shop

One filament, in the bulb, is burned out.
remove the bulb, look through it and see if it has two filaments.
replace if necessary.

Hi Jorge. Por ahora, s?lo conduce a la misma velocidad que todos los otros conductores. En ese a?o, un problema com?n estaba poniendo demasiado lubricante en el cable del veloc?metro, causando que se pegue. Golpe? el tablero de la rociada unas cuantas veces y ver si eso lo har? correr. Quiz? deba reemplazar el racimo del instrumento. A veces se encuentran disponibles en los patios de demolici?n del autom?vil.
