You cant say if you have a problem, put it down to it being a 15 year old car. I also have an E registration Toyota Celica Automatic. I service it myself, but i have never changed the gearbox oil and the car still works today. Its done over 230000 miles, same engine and same gearbox. Maybe because itsJapanese. Ive just seen a thread on here where a gentleman has problems with his 2000 728i Automatic Transmission. So its put me right off german cars. I do know Audi have problems with their auto gearboxes which they wont admit too still, but i didnt know Bmw have the same issue. Its a shame because the car did look nice
