They say clutch but gears all working. Has driveable power in 1 and 2 gear. Slows down on up hills especially 3 and 4th. Can reverse etc. Feels like fuel not getting thru. Have changed spark plugs fuel filter etc. Also key was battling to release from ignition. Last night it didn't want to start like a flat battery. I'm a single Lady and get different answers The call out team who changed filters etc picked up no issues on callibrator PC . but never took it for a test drive and was still 'flat'. When they did they said I need an entire new clutch plate kit but clutch still working and gears?
