No engine braking in 3rd gear

[SuberNatural]

1st gear and 2nd gear both stay right with the engine.

D4 idles down after a few seconds of coasting as it should.

D3 goes right from pulling in gear to idle (as if in neutral) then after a second or two hits 3rd gear and then neutral until the car slows.


I have no codes on the TCU.
The trans resistor is plugeed in and good.


Any help would be appreciated. I just had the trans serviced etc.
