Hi Bob
These are after market units which adjust the throw between gears and make it tighter
suspect its just the play at the linkage at the u/j slightly more stiffer more precise but
not to every ones taste
So yours may need a good oil change and the linkage looking at as linkage hidden under the
heat shields

Thanks Kev.
FM passed the MOT today with just one advisory (hand brake at bottom limit) Gear oil to be changed tomorrow and UJ inspected. Gear oil had better be good at £78 for 3ltrs ouch! :o
worth it though if it fixes the problem.

Thats very gentlmanly of you John, thank you very much for that very kind offer. I will see if the new oil and a bit of TLC on the UJ works before I make my mind up but if its looking like a box strip job, i'll Google the route from Glos to Grimsby and it will be very nice to meet up again.
I'll show my ignorance and ask whats a VSS?
Regards,

Bob

VSS the unit that creates the pulse that goes to the cruise control and speedometer.
Easy to swap over , when the gearbox is out.

As John says vehicle speed sensor top off gearbox give a good soaking with WD 40 if your
gearbox is FUBA and needs to come out i use an old wood chiesel to crack the bond ;)

Good news, the new oil and UJ service seems to have done the trick. Gear changing is very much easier and smoother. I cant tell you which had more impact, but previously there were two notches and occasional clunking when changing gear, now there only seems to be one. I havnt tried a racing change yet (and promably wont) but changing normally and with respect to the 27 year old engineering, it likes to disengage the current gear to neutral smoothly and without drag, think about it in neutral for a split second (as the synchro speeds the engaging gear up) then slips into the new gear smoothly (best when the oil is warm). Not like new, I suspect, but pretty good and much nicer to drive now, so a good result for me.

Also a bonus was that it didnt cost me a bean. The garage that all the company transport goes to have a cylinder head with siezed and rounded head nuts they wanted to mill off with a hollow cutter, but the shank is too big for their drill, so I welded on a dummy shank and machined it true, so being gentlemen, no money changed hands. You scratch my back and I'll comb yours! I think I got the best of the deal judging by the location of the UJ but I guess a four post lift helps.

So I hope thats useful info for anyone with stiff gears and my grateful thanks to John, Kev and Malcolm for the help and advice. Also Stuart McCrudden of Gear Tech who was rightly sceptical about the syncro's. A lesser man would have had the box out, (including me). Gear oil used was Red Line GL4 75W85 MT (manual transmission)
