    Hi everyone — quick question: can someone confirm where the transmission fill plug is located and, if possible, share a photo of it?


    I’m trying to verify whether the plug I’m looking at is the transmission fluid fill plug (or if it’s actually a fuel plug / something else). Thanks!

    From reading through attached, looks like fill and drain bolts for the transaxle are socket head cap screw style (female), with recess for 10 mm hex driver. Info:

    Nice bolt head - how about a zoom out picture so we can get an idea of the location of that bolt?
    FWIW; the fill plug is neat the output CV shaft.

    TE means that the transaxle uses TE fluid.

    Evidently, the drain plugbwas upgraded on the OP's vehicle to make sure that the technician knows that the transaxle uses TE fluid and not the previously used WS fluid in earlier models.
