The CE code in 1968 would be for a Chevelle or Camaro with hi-perf 396...since there were no TH-400's behind the solid lifter big blocks in 68 [except Gibb Novas], that would mean an L-34 or L-35 engine.

the 490 date would be sometime in early April of 1968.

Thanks Tom -- looks like this is a pretty early tranny. I know that if left in drive at WOT it will shift a skoshi over 5000 RPM ... Craig

You can move that shift point up by changing the governor or modifying springs/weights...I may have a hi-shift point unit in the parts. dept if you are interested
