Oh, and no, my tranny has never been rebuilt, and at 260k miles and 10 years of life that's probably why the shifts are groggy.
"old"FM1187 & I-35W is where the pics were taken.

A TCM reflash with the latest software version isnt a bad idea.

Has the transmission had regular maintenance?

DO NOT use Dexron VI ATF in your 5 speed Allison, The BEST fluid for a Allison is called TranSnyd. it can run from $40-$60 a gallon.

Or run Dexron III......But change it (2 gallons & filter) every 30-50K miles
