Hey all

just the other day I noticed that when in drive and giving the car gas it like sputters.... tbi 5.0 with 700r4. normally when I put the peddle to the floor it down shifts and just takes off. now when I give it a good amount of gas it doesn't have the response it used to have. recently did full tune up, new cat, new vac lines and had a check valve replaced all for NJ inspection. car revs up perfectly fine and hold a good idle...... could something be going on with my trans?

Thanks
