06 MC. 5.3 hard shift 1-2 gear
 

HI all,
My 2006 ss just started doing a funky hard shift between 1st and 2nd gear and sometimes 3rd. This happens while in drive but not when I manually shift. I've had the fluid flushed about 4 months ago with no probs until now. The fluid now is clear, full and not burnt. If I drive it real easy, it does minmize the hard shift greatly.
Any ideas out there?

Thanks, Jeff

are you setting a code?

No check engine light...havn't checked for code

I know in my 03 Monte It was doing something very similar but in 2-3 and ended up being the valve body
