Honda CRX Auto not changing up smoothly although Transmission fuel fine
I have a Honda CRX 1.8, 10 years old, automatic. It has now done 105,000 miles with very few problems and has been utterly reliable. I love it and I never want to get rid of it but it's developed a problem over the last month. Sometimes the gears won't change up smoothly and it revs away, labouring to get into gear. Coming down the gears is fine, it's just changing up (no particular gear is worse) and once in top, it's fine. I checked the transmission fuel and the level is perfect and the fuel's clean so I don't think it's the clutch. I am guilty of driving all the time in auto mode so maybe this has caused the problem. When it happens, the problem exists for about a few days, up to a week, then goes away for a bit. It happened again this week and I started to use the individual gears a bit to see if that helped and today the problem has subsided although I don't know if it was this that helped. Any ideas as to what this problem is and who I should go to to get it fixed please? Most grateful if you can help.
