Discussion:
Shifts to FWD or REV but no power

Upon shifting to FWD (or Rev), I can hear the solenoid on the transmission engage. Pressing the gas, if in a flat area, the forklift will move slighly in the direction of the shift, but it has no power thereafter to move or climb. If I press the gas pedal slighly and release several times while on fwd or rev (seems also,that if I play with the up/down hydraulic) "something" engages and now has power. Upon shifting out and then in again, same problem. Transmission and hydraulic oils are good.

The problem may be in the transmission control valve. The springs need to be checked.

Hi,

We're you able to solve the problem?

I am in Poland now having the same issue with a g15s
Switches gears finely, on flat surface it moves slowly. Even the smallest hill stops it.

Clutch has been professionally reworked already

Pressure problem I guess
Where to search?
What to have a look on?
