I could do that but I’d like to at least see tradesman doing the job and not just anyone as it can turn Pear shape pretty quickly!!! Like the old Saying…” A little bit of Knowledge can be Very Dangerous” However like I have mentioned many times the input shaft has several different heat treatments over the years to improve its ductile strength.. Another words, to be able to handle the stress without Deformation, fatigue or fracture. . Given enough power and sticky tires it will still fracture. E pack which is first used in 4th Gear is too small and takes a lot or torque and as such needs to be increased. Park D Rev B & D Nu D 1st A & D 2nd A & C 3rd A & B 4th A & E 5th B & E 6th E & C B is another that takes a Beating in third and needs to be beefed up. A, D & C wear but not an issue but worth tiding up whilst in there. Keep in mind the clutch capacity is measured in force over area and as such if you increase either the capacity will increase. However the increase in Area will reduce the amount of pressure required to engage that clutch under normal driving and as such the shifts will be much quicker requiring the ZF to re learn.
