96 2dr 4x4 4.3L automatic stumbles when turning right ??

My 96 2dr 4x4 S10 Blazer seems to stumble when turing right from a stop. Gas tank full or empty does not make a difference, warm or cold, has 205K miles. Transmission fluid clean and full new plugs cap rotor 1 year ago, fule pump 2 years ago fuel filter 1 year ago. It statred about 1 month ago I do not see the tach fluctuate seems like the motor stumbles but could be the 1-2 tranny shift. No codes thrown any tips ???
