Muncie transmission ID-1969 Z28

[JST69Z28]

Attached are 2 photos of the 4 speed trans in my '69 Z28.  It is a Muncie 4 speed, case is 3925661.  The stamped codes look like CC1(a closer look may be CG1 or C61?), then 35585, but I can't correlate those into a final ID from the decode chart I received from the team.  Any help for a final ID would be appreciated.  Thank you.

CC1 is an over the counter service case and 35585 is the serial number. More info HERE.

Ed,
Does CC1 confirm the trans is not original?  If so, that's another surprise, and I'll check back with the 2 previous owners I know for more history.  I have had the car since 1982 and made no changes.  Just trying to decipher more of the car's history.  I checked the differential code and it is BU 0624 G2 so according to the notes the car was a late June or later build.  Thanks for all the help.

Yes, that's correct. The case itself is an over the counter service replacement but it could have been used to rebuild your original transmission. However, that being said, if the transmission had issues while the car was still under the 5/50 warranty, they usually just replaced the entire transmission and didn't go through the trouble of rebuilding it. If the transmission had issue after the warranty, it could have been rebuilt by a dealer or even a transmission shop since the case was readily available at most dealerships. Unless you find paperwork showing it was rebuilt, you'll probably never know.

Would a 1969 have a 5/50 warranty, or 12 months/12K miles back then?

All three years came with the standard 5/50 warranty. Even the Z28, ZL1, and COPO cars!
