I am told you have to use a scan tool ""DBR III" (see ebay for tool) to reset the tranny codes after oil change. This is a "relearn" process you have to do for this car, else you could have eratic shifts. Normal odb scan tools will not do this, other than clear engine codes.
However as my trany works fine 87000KM, I will do a SIMPLE drain and fill from the botton, and replace the filter and gasket. Wil lNOT try to remove ALL the fliud, else may upset the computer.
Dealer wants $90 labour plus parts for tranny service, which will probably hit me for more like $300.
I will also change the plugs at 100,000KM with NGK iridium. I used iridium on my Toyota and work wonderful. They are expected to last 3 years.

 

a quick lean is needed if U replace the solenoid pack rebuild or replace the tranny.
Put champion plat plugs back in there nothing else
