[ROVERNET - UK] Passing Gear

[Michael Pellow]

Hi A Gearbox specialist down the road from me gave me a simple but very 
effective way for setting up kick-down cables on BW 35 boxes.You have 
the fully warmed up (at least 15-20 Km drive) Drive down a level road & 
roll to a stop.The box should drop into first just before the car 
stops.He said the this is so close that no further adjustments are 
needed.Loosen to drop the KD point & shorten to raise.
Make sure that the cable is connected.He cable changes the pressure in 
the gearbox giving the variation in change up speed and selection of the 
bands.If it is not then the gearbox is running at low hydraulic pressure 
all the time i.e changing up to top by 25-30mph.This is NOT GOOD as 
under load the bands will slip and wear quickly.
