A4 deep pan
In the pan rail of the transmission, there's a bleed off vent for the servo. This vent is a small hole in the pan gasket rail. The stock pan and gasket are notched to clear this vent. Some aftermarket pans and gaskets don't have this notch and the vent port gets covered up. There was even a GM bulletin noting this after they had some warranty and service issues caused by aftermarket parts.
It’s in the pan gasket surface just under the servo, the big round thing on the side of the case. This hole needs to be clear. Check your units guys! Covering this hole can cause the servo and clutch packs to hang up and wear out very quickly.
Please help ASAP! Thank you so much!!!
Usually, these pans come with a filter that'll fit the pan. None in the box?
Have you called Summit?
Sometimes these aluminum pans have cast in posts that the filter sits on. Does this pan have them?
I have the Derale pan on all my vehicles.
If you've added an auxiliary cooler, make sure it's the stacked plate type, not the tube type. Tube type coolers do almost nothing compared to the plate coolers.
