So I changed my manual gearbox oil today to see if it would fix the problem I've been having including difficulty to change from 1-2, and from neutral to reverse.
I used Penrite 75-90, as recommended.
But now, I find that when the car is turned off I can go into all the gears no problems. However, as soon as I start my car and try to put it into any gear with the clutch depressed it is almost impossible. No grinding (except for neutral to reverse), just have to apply a lot of pressure to actually get it into any gear. But no problem if the engine is off.
I don't understand why this would be? Why would I be able to select gears easily when the engine is off, but with the engine running, I have heaps of issues getting any gear?
I checked clutch fluid, there is plenty. No previous signs of clutch slipping.
