My trans is shifting really hard when I put it into drive. It will almost turn the tires when shifting from 1-2 and jerks slightly when going from 2-3 and almost normal when going from 3-D...I have got 91K on the clock and I just flush it 6 months ago. This problem started this weekend. Where should I begin?

Thanks in advance

Did you get it tuned, or add a shift kit, or make any similar changes to it recently?

 

none whatsoever

 

Hi If the shift timing is correct and thee are no codes stored ,I would service the transmission and replace the pcs(presure control solinoid)

 

Is that something I can do my self....the pcs..?
