so ive just had new bearings put into my gearbox, its out of a 85 drover and when i got it back it was very firm to change gears but after a few hundred ks, it now sometime wont go into any gear at all, it happens mostly going from 3rd to 4th, i have to stop and play with it till it goes back into 5ht before i can then go back down the gears and go again, any odeas
thanks james
