ok heres the thing this weekend i took out my tranny. and replaced the front pump and torque converter. well everythings done good but now i go from a roll the car just has slow boost. and has a hesitation badly like not getting sprk or fuel or something wierd. but also from a stop i power brake it and to bout 30 mph its gone but bout 30 mph it just like stops pulling almost like it dies so it pulls then stops then pulls again something to that effect any thing to do with tranny or any other suggestions???
