i’m having a transmission issue. 2002 camaro 4l60e, my v6...in overdrive trans shifts are off, 1-2 are good, 2-3 shifting i feel like it’s in limbo deciding what gear to go into, hearing a thud, hit the gas and shifts into third easy. 3-4 is good. when i actually put it in drive, not overdrive, the trans doesn’t have this issue shifting. curious what it could be or what i should look at. solenoids?
