Hi all, on helping my buddy replace his auto box on his discovery 1 300tdi. Upon inspection we have noticed no kickdown cable (probably what killed the box). Replacement box came with kickdown cable installed so we have ordered the brackets for the injection pump… my question is

what is the way to adjust the kickdown cable so it’s not too tight?

Check the setting of the kick down cable, if it is too tight the gearbox will think you have more throttle applied than is the case. Check and adjust the gearbox accordingly. As a guide the looser the cable, the earlier it will shift, visa versa the tighter the cable, the later it will shift.
