DSM Auto trans converter return fitting

The fitting has 2 flat sides for a 20mm wrench. This is so you can hold the fitting and tighten down the hose end fitting onto the trans fitting.

The 6an fitting is secured in place using a E clip that slides into the receiver grove on the fitting once the fitting is slipped into the hole on the trans. Each kit comes with 1 fitting, 1 E clip, and 2 o rings. One that is installed on the fitting and 1 for a spare.  

NOTE Everyone at this level or doing these types of mods should be monitoring converter charge pressure. Depending on the converter used, with or without a filter, oil cooler, line size/ length will all factor if or what size restrictor should be used. It's not limited to this product either. Several other factors play a roll in convertor charge pressure. Some applications need a restrictor and some do not.
