Rover 400 diesel, manual gearbox. Can select gears ok when engine is cold, but after 15 mins running it is very difficult to change gear. Car runs perfectly on short journeys, but once the engine is hot it is always the same. With the engine stopped when hot, it is easy to select all the gears, but once started again its very difficult to engage a gear.
It will be best to get someone to check the hydraulics of the clutch. That is a common issue.
Get a workshop to drain the gearbox oil and flush the system. A tell tale may come from the drained oil if the tranny is near end of life.

Sounds like you have yourself a bad shift solenoid pack this is mounted on the front of the transmission under a thick rubber boot and has an 8 or 10mm bolt holding a plug into it, these usually fail hot as it is an electronically controlled solenoid and there are tiny little springs and magnets inside that can stick also while you are in there do yourself a favor and change the two speed sensors on the transmission they are about $22 each and can also cause the problem you are explaining. the shift solenoid pack is about $120 on ebay and some sellers actually sell them along with the input and output speed sensors you may try changing those first and see if it solves it but i have a feeling your solenoid pack is failing also when you change these parts it may take the computer a few trips to relearn shift points but you'll know it fixed it right off the bat.. please rate and good luck -jeff

try thinner oil in the gear box also bleed the cluch and adjust it this should fix the problem

hi i am dieter
im dave
here is something to try
keep some cold water with you and the next time it happens very quickly get out and pour the water on the crankshaft sensor then restart. If it starts right away without the usual two minutes than you will need to change this sensor. The sensor is easy to find you will see a wiring harness around the crankshaft pulley(the large one at the bottom the basically runs all your accessories like the p/s pump, alternator, water pump). Try to famaliarize yourself as to the location of the sensor first so that you can try to restart it within about 30 seconds.

hi from uk could you please give a little more info ? what make/model car ? has this problem occured suddenly? has car been layed up off road some time prior to this unable to select gears ? this problem sounds very much like the clutch drive plate is either stuck to flywheel hence question above ? or it is sticking on primary/spigot shaft for some reason and failing to disengage drive to g/box? how does clutch pedal feel ? you might try selecting 2nd gear with clutch fully pressed and h/brake on then try starting engine if engine starts ?runs then put slight revs on and slip clutch a few times this may work if plate is sticking? if you come back with update may be able to advise further
