Finally got everything dialed in or so I thought. Did great at first as far as downshifting into passing gear once I got everything adjusted right. Drove for the first time yesterday in a while, and it would downshift into passing gear, but once I came to a stop and then took off it wouldn't shift back up until I put it in neutral then back in drive and it would shift normal again. Any ideas? 70 T/A 340 727
