Hi,

we have an 3,5t diesel Toyota forklift (8.000h). The issue with the transmission started as the hose of the transmission cooling line broke and was leaking so much that the oil in the transmission overheated, the result was that that the forklift went slow into the forward gear (sometimes went it rigth away, sometimes it took more than 10 seconds)...the reverse went well.

I took apart the transmission, the seals were all hard, also the plates were worn out, the steel ones were also a little bent. I changed everything, put it together, put new oil in. It was running fine after that (yesterday). Today we were using it a little more so the transmission got really hot and the forklift started to had less power, as you took like 2t little uphill it didnt go.

Did anyone had issue with the cooler, maybe it is clogged?

Thx.

Nejc
