Matbro TS260 by forward no power

[Vitos]

Matbro TS260, year 1996 by using forward doesn’t have power. It’s becoming worst every day. Backward it can climb mountains.
The forward clutch pressure is 5, the backward pressure is 9.
Do I need to disassemble the gearbox?
Where should the problem come from?
Does anybody have an exploded drawing for this kind of gearbox?
Thank you very much!

will want an overhaul, engine out new transmission pump and reseal pump housing, recon the converter.
Transmission out and reseal the clutches, and might want the casing boring and sleeveing if the clutch drum shaft has worn in to the casing were the sealing rings are.

All common on old handlers

you want 140psi to 150psi in clutches when hot, 160psi would be quite normal if cold.

9bar is a little low and 5 bar is very low so forward pack discs will be burnt out.
