Description:

Box has been used in a K series Caterham, only 4 hours in my ownership the past 4 years

oil changed every 2 events... only used in sprint races or actual sprint events. 
 

box has been sticky to shift into 5th gear, albeit is shifting fine when on the bench and fine when it was in car on stands. 
 

could be user error! As I have been used to bike engines prior to this box, and have always struggled with the effort needed to shift this box in comparison...

maybe just needs a longer shifter (mine was already hitting dash so could change) or maybe stronger hands/arms!!! 
 

priced a grand less than these generally sell for to allow someone to get it checked over/adjusted... or maybe a new longer shifter got. 
 

happy for any inspection, it's out of car and cover off... local gearbox guy has said the box is fine, and extremely light wear.
