I have a Clarke Forklift at work and it was not going into gear easily. You would have to rev the engine to get it to engage. A dangerous situation potentially when loading and unloading trucks.
Today I added 6 oz of Auto-Rx to the transmission and now within a minute, I have a smooth shifting forklift. The mechanics that had been servicing the unit said it needed a new transmission. Little do they know about Auto-Rx.
My question would be, how long to leave it in the transmission before I drain and refill?
