Gear change sticky when warm.
Discussion
My 94 Griff 500 (Serp/T5 box) is the first car I've ever driven that the gear change becomes stiffer when warmed up. Every other car becomes looser when warm.
It's not undriveable, It just needs a hefty shove between gears. It's fine when it's cold. The clutch seems ok with no difficulty in selecting gears when stationary.
Is this normal? If not, what can do to sort it?
Any help much appreciated. CRAIG

Might it possibly be the top hat bush and ball section at the bottom of the gear lever (I assume the T5 box is similar to the one on the LT77 box) as this is prone to wear and results in misalignment when changing gears.
Mine was first and second but they are all different.
Just a thought and good luck anyway

I have the same problem and tried this first - it improved matters, but didn't cure it. Clutch bleed is next and I might try and get into the shifter mechanism to check the plastic bush that tends to crack.
I had the same problem and once the oil had been changed it was and still is sorted
But as Slacey says changing the oil is the First job and fingers crossed should fix it especialy if its covered lower than average miles.

Craig i would certainly check for dry bushes on the remote linkages,my gearstick was getting sticky on hot days i had all ready changed the box oil on my maintainance once over when 1st purchased so knew this was not the problem and the clutch fluid had been renewed also when resealing the slave cylinder,when i looked up under the car the linkages were bone dry a shot of spray grease(comma spray grease is good for this or motorcycle chain lube) round the mechanism as improved things alot but i feel the need to strip & inspect the various bushes (possibly sloppy)when i change the carpets my car as a fare bit of mileage though so can only think that heat & road grime dryed the linkages out,good luck.

One of the guys in our region (c3c) had the same problem with his Chim. He changed the oil in the grearbox and the problem was, and still is, solved. It seems unlikely but it fixes the problem.

Three of us actually, which tends to suggest that the first thing to do is change the oil.

Right, as an update to this I had the box oil changed and the clutch bled (the cylinder was full of black crud!). Although it now shifts quite slickly, the magnet feel is still there when the gearbox is warm.
So, what next? Is there a remote linkage on the T5 or is it direct? We did also check the clutch fork which looked OK but I guess if that's warped it could be the cause. Any other ideas?

Clutch dragging through old age/wear&tear but the indication here is normally a heavy clutch pedal and difficulty engaging 1st gear when hot,i would say crunching reverse gear but they do that anyway unless you engage 5th gear 1st
The clutch was changed about 11k miles ago by the previous owner. It never feels like it is dragging as the bite point is always consistent and the pedal isn't heavy. First generally goes in fine, it's the 'magnet' effect pulling it out of third mostly.You may find this thread interesting. Maybe worth trying different oil ... ?

How easy is it to change the gearbox oil? Yes, mine stiffens up too when it gets hot.
Oil is dead easy. Remove the filler plug (some may leak from here), once that's out remove the drain plug at the bottom. Drain fluid fully, then replace the drain plug. Filling can be a pain, easiest is to use a large syringe / basting pump or attach a length of hose to the oil bottle and squeeze in. Fill until the fluid is level with the filler hole (2.5 - 3 pints). Ooer missus!
