At my Corolla Verso 1.8 BJ 2002 124Tkm the gear bearings had to be replaced. When I picked up the car from the workshop I was informed that the 5th gear sometimes goes bad. I should observe. I probably will be the clutch, it was said. I tried for a week and found that the problem usually occurs in the warm state. Mostly it is when I want to switch from 4th to 5th gear. Since the 5th gear block, but switch back in 4th gear does not work. In the beginning the first gear did not go in, but now mostly without problems. Now almost all gears are affected. The bearings were replaced by the gearbox and a syncroring. Before I had zero problems with gear or clutch. Therefore I don’t think of a defective clutch. Workshop has now some other oil pure, but was also only short-term improvement. “We don’t get better” was the last statement… W I’m sure the only thing that’s going to happen is to go to the lawyer.
