CVT issues

[Campbelden]

Problem came to life 5 months ago, vehicle reved up but felt like in high gear. Shut vehicle off waited restarted and drove fine. Changed fluid and filter vehicle had 170000 miles ran good no issue till 4 days ago. Vehicle would not go in gear, had it towed home dropped pan fluid a little dark but not burnt, ordered new valve body matched what was in vehicle news fluid and filter. Till this time no codes. Reassembled and started vehicle drove around block vehicle would not shift out of first. Did overall scan got a P0744 code one time cleared and checked all sensors. Now at point of not knowing which way to go, fluid level is correct nothing shorted to ground as far as Solenoids go am lost. Realize might be a mute point but still would like to figure out.

P0744 is a Torque Converter Lockup code, that shouldn't prevent the tranny from functioning. Did you load the IP Char data for the new VB into the TCM? Some will run with the old data still in the TCM, some won't.
