TH-350 vs. TH-350C filters:

[vandelay industries]

Is the trans filter for a TH-350C different from a regular TH-350?

i thought the 350C has a notch cut out of it vs. a regular 350 which is square.

However, the AC Delco site lists the same filter as compatible with both transmissionses.

i don't want to drop the pan unless i'm sure i have the right filter. i have a 350C

They are different but fully interchange on a 350 or 350 C. If using the 350 filter on the 350C care must be taken to avoid the filter contacting the TCC solenoid body and grounding it, the 350 C has a corner cut out of it to prevent that problem. The 350C filter uses a Dacron element and is actually better for trapping contaminants.
