Hi, need help with a Hyundai 25L-9A, has slow drive in forward and reverse until it warms up, then it will drive ok.
Pump pressure is good, handbrake valve and direction valve replaced. Valve block stripped and cleaned, but still have slow drive until warm.
Any ideas???

Both directions movement clutch piston seals have caked, replace seals and machine will drive as designed.
Both forward and reverse clutch piston seals?
Hi, yes the problem was the clutch pack piston seals had gone hard and brittle. The clutch packs themselves were OK, just needed to replace the 2 seals, inner and out seals on the pistons.
Had 3 trucks all doing the same, must be a common problem.
Did you find a solution for this issue? I'm having the same problem.
