Looking to change auto fluid but a little confused despite seeing many forum threads and you tube videos as to fluid type and location of fill plug. So just to outline what to search for clarity, sorry am not a computer type so unable to provide direct links.
5 speed auto transmission fitted is Aisin Warner AF33, fluid should be specified as JWS3309.
Information as to fill, level, drain and 3rd gear anchor (do not touch) can be found by:
Google where is filler plug on Aisin Warner AF33:
Search results hopefully are:
www.atra.com>gears. - clearly shows position of prior level dipstick now plugged with Torx type plug, and fill plug with hexagonal fitting.
shop.uktrans.biz>catalogs. - down load in pdf of original GM training material with technical information.
Fill plug on my auto was completely obscured by cables etc hence some confusion.
Hope this info helps others with uncertainty.
