First check that your clutch slave cylinder is not leaking and that when you start and move van in 1st gear , the van moves when clutch pedal is just starting to lift with your left foot on the clutch pedal; Then stop van running put in neutral, now you know if the clutch is leaking or not,
For gear selection stiffness , i drained the gearbox oil and refilled it , but will do that again, using fully synthetic gearbox oil 75w/90 GL5 gearbox oil needing 3 litres ,and use a long tube so you can let gravity cause the oil to travel from the bottle into the tube which will fit through the gaps from looking from top of engine with bonnet up , fitting the end of the tube into the hole where you fill the gearbox oil up , using 2.35 litres of that oil to refill the gearbox ,the drain plug Nm setting used by myself was between 43 Nm and %0Nm, so 46.5 on a torque wrench and the size needed is a 24mm socket for the drain plug underneath in the middle of the transmission housing, the filler plug as i had no small torque wrench i looked in manual and it said 40nm, so i tightened it using a 17mm socket and wrench , the filler plug bolt is just above the passenger side driveshaft on the side facing the inside of the passenger wheel from laying under trhe van an using eyes to look at the position ,
