Hello, look they can be several things but I would begin by seeing the career that your clutch has, and what sounds most to me is to be is to check the transmission and see the wheel, that is to say the black buoy that makes the changes feel soft, it is when it is damaged give the symptoms you mention, in the best case it is changed to a new one, make the tuning to your transmission and ready to enjoy your ship And if you can comment on the results atte, Isai Curiel Greetings.

Ahh I forgot to check the leagues of your transmission and in general electrovalves, selectors, etc. Atte, Isai Curiel.

The last thing [Strike] isxiji2001 [/Strike] usually makes more sense.
Do not start disassembling the box before checking some things. First Scanare and see sensor and solenoid function from the box, if they are ok carter and see the sliding valve because sometimes covers or obstructs.

If these are fine ... you are screwed, you will have to disassemble the box because they can be stamps or discs.
