Good morning,
I am looking at C6 rebuild kits and have found the filters don't always look like the right one for the year range.
The kits I am looking at sometimes say year range 67-76, 72-76 or 69 and up, do the filters interchange?
I also notice some kits mention plate thicknesses, are there different stock thicknesses?

My transmission is PGA AU3 AC013692 being used in a different car.

Please let me know what you know.
Thanks,
Scooter

It is nothing to do with the years . Filter type goes by type of pan . There are 3 different ones .

Thank you for the reply,
I found some pictures of pans and see what you are saying now. Mine has only the notch by the modulator and not the chamfered corner. I think from the tag on the transmission it is a 1973.
Ebay item: 323005821967 from Globaltransmissionparts looks like it has the type of filter that I was thinking mine should need? I wish I could shut the car down long enough to take it apart and confirm what I need, but my son need the car for work.

Thank you,
Scooter

You need to be very careful. Sounds like you might have just a shallow pan. That one in your ebay item has a rubber grommet which is for a 4WD type pan , an extension tube fits in the grommet

If that filter with the grommet is mistakenly used in a shallow pan , the grommet can actually seal to the bottom of the pan and starve the trans for oil.

In this link there are two filters , the one on the left is for a std shallow pan. The one on the right is the medium pan.
The medium pan will should have both front vertical corners chamfered off at a 45 degree.

This is a better pic of the 3 types

Thank you for the information, I wondered what the difference is.
Before I purchase a kit, I will ask the seller about the filter to make sure I purchase the correct one.
I have noticed some of the kits have different numbers of plates provided. I am wondering if that is a reason to wait until I have the transmission apart to determine my needs for sure?
I may have to tell my son to arrange for an extra week of transportation to work if I order parts after it is apart instead of before.

Thank you,
Scooter

Kits usually contain enough stuff to cover several years.

You will not likely be able to use all the parts.
