Beste Emiel,
Als ik goed geïnformeerd ben is er zeker in NL een goed alternatief verkrijgbaar voor de Jatco JF403E olie. Het is de Eurol 1100 ATF olie met zelfs nog betere specificaties als de origineel voorgeschreven van destijds. Normaal direct leverbaar bij bijvoorbeeld:

Ook een verhaal wat wellicht positief kan bijdragen is dit:
The gearbox oil what is used was Eurol ATF1100, and not Texaco JF403. When this firm (who did the flush) is overhauling an automatic gearbox for a Rover 75 also the Eurol ATF1100 oil is used, and they have done many without any complaints. This oil has a better spec then the original JF403 from Texaco. I have phoned Eurol oil laboratory in Holland before my appointment for the flush, and I was assured that ATF1100 is indeed the right oil for my gearbox. Eurol also told me that a gearbox oil flush is much better than the normal gearbox oil change because there is almost no pollution of the new oil by the old oil.
Unlike the procedure of Rover that the automatic gearbox should be filled on an gearbox temperature of 35degr. Celsius, the firm who did the flush did not do this. When flushing or when filling a automatic gearbox after an overhaul gearboxes are always filled at ambient temperature. The oil will expand if it’s getting on it’s working temperature, but I was promised that that would be no problem at all.
When I called transmission experts, there are not many who can do an automatic gearbox flush here in Holland. And those who can like to be a bit mysterious about the procedure. For instance being present at the procedure is not done, and if you can, taking pictures is not allowed. All transmission experts who I have spoken to told me the Jatco gearbox can be filled with another oil as long as the replacement oil is at least the same spec or higher than the original. Most normal driven automatic gearboxes with problems are caused mainly by NOT refreshing the gearbox oil on time. Gearbox change intervals should be between 80000km for a new gearbox, and 50000km when the gearbox has done 150000km or more to be safe. No need to change the gearbox oil what is written in some manuals of car brands is just a marketing issue.
Not one specialist has told me different.
Down to earth it is not all that high tech as I expected, but very effective! If you have a ramp or car lift to put the car on it could be a DIY job if you want. The big advantage of a flush is that all the old oil is replaced instead of just 55%.
This post is only intended to share my experience of flushing an automatic gearbox. NOT to start the discussion about gearbox oil again! The decision to do a gearbox flush is that I want the best for my car, this is also the reason why another (in my opinion better) oil was used. I have done 150km after the flush now and the gear changing is some smoother than before.
I hope this post will help others to make their own choice what to do when the gearbox is due for a service.
