Help with Prowler 6 Speed Gear Oil Fill and Drain

[MpinLA]

Hello All. Full disclosure. Not a BDM but a custom that shares alot of similar gear. Just purchased and changing all fluids. Trans is a Prowler 6 speed and don't know where to drain and fill fluid.

Can't find any info onlin or a search here
Is the drain a small allen screw on bottom of right side cover? Can I remove the speedo sensor and fill there or through the top inop neutral safety switch? I'll use an extraction pump if either of those sensor gains access to sump. Adding some pictures to help. Thank you.

This is the drain plug in the pic below



I do not see the fill hole which is crazily odd...so if it was me I would put the oil I drained in a cup to measure the ounces...but with that said most all transmissions hold between 20 and 28 ounces depending on how long you let it drain...and yes if no fill hole can be found I would do it thri the speed sensor

Thank you. Seems some of these trans companies share the housings but I've checked Baker, Revtech, HD, Ultima and seen a dipstick plug.
