Chances are they did not actually repair and update the baypass and regulator vales and just cleaned the VB. The baypass valve wears out and sticks. It can�t be cleaned or even replaced, the bore has to be honed and a redesigned (Sonax) valve used.
Bring it back.
Also do a search on code 1744 and Torque converter slippage. ( I think the code for 95 is 640, or 634. but don�t quote me).
