Mahindra 6075 won't shift into fwd or Rev

[speedy223]

Shifts all gears but when you put it in fwd with the electric switch nothing same with Rev. Neutral lights up when selected goes off in fwd or Rev
Only 163 light hours. Quit in the middle of mowing. Clutch feels fine.
I am lost on this tractor never broken before where should I start. Yes it is under warranty but it is in a very inconvenient spot on 4th of July weekend. No immediate fix so I would like to figure it out
Any help appreciated

just as a close to this ancient thread: realized i forgot to.

it sheared the link from engine to hydraulic pump shaft and it was replaced under warranty by Mahindra. they said the new part was upgraded.

no problems since.
