Mahindra 5010 cab hst
Had cab off Mahindra 5010 to repaint including peddle bracket assembly...all back together but no reverse ...when keyed on the F light is illuminated and I have to move both pedals slightly to register N so it will start ...
When idling, F light remains illuminated but cannot get R to engage ....

Each peddle is attached to a potentiometer to control pedle position signal ....I have a pair of Volvo marine engines which use similar configuation to establish fwd/ reverse and speed and there is a proceedure for relearning the control head if needed .... I.e.key on holding a button then moving lever through various positions and pressing a button at each stage so system learns the position and then its is stored in the ecu....
Is here a similar proceedure for the HST transmissions on these tractors?

Sorted ....removed peddle assembly and adjusted potentiometer housing - mount allows for about 10 degrees of movement ...all good - now starts in neutral and fwd and rev working as intended....
