Anybody know what size the O ring is for the trans cooler at the pump?

Mine is leaking.

Thanks,

All I could find real quick was "rubber o-ring s7 (2 recommended)"

Don't know if that can give you any clue?

I just replaced mine with OE, but before putting it in I compared its size to some in my Harbor Freight O-ring assortment and it matched up (to the eye) perfectly to one in the kit, I don't remember the exact size. Invest in a Viton O-ring assortment kit, it has easily paid for itself in the few times I have had to rely on it.

I can measure one tonight for you if know one gets it sooner.

O.D. is 20mm
I.D. is 15.5mm

This was from a fairly fresh, but used, o-ring.
