I'm about to remove my high pressure pump from my 06 td4..... am i right in thinking.... car in gear.....pulley removal tool is enough to lock the engine without the timing pin?

Linkages are all connected though it looks like there's something broken on the linkage that moves the gear lever left and right.... I'm able to move stick inside the car with movement showing at the gearbox and vice versa but the linkage doesn't appear to me moving anything inside the gearbox

Folks I've had my TD4 sport Freelander 1 for about 6 months, yesterday on my way home i could only select gear 3 or 4..... no 1st, 2nd, 5th or reverse. I've checked the linkages and all are intact. Suspect there's an issue where the linkage connects to the gearbox.... any idea where i could view...
