Everything was working fine. Highway got congested so I went over the median. When I came off the curb and pushed the gas it would only rev up. Checked linkage…still moving when I move shifter. Checked fluid…good on fluid although it could be changed. Im lost. Please help!

Automatic 4l80e 2500hd…just had transmission rebuilt maybe 2 years ago
