1997 SE Pont.Trans. Issue

Post by 97SEBonnevilleMan »

Hello everyone :) I have a 1997 SE Bonneville non supercharged setup.
My issue is hesitation/surging to go into overdrive around 40-50 mph,once its on the highway it will do 70 -80 mph like nothing ....Tranny was replaced at 70,000 miles the car now has 132,000 miles on it now fluid has been changed when I put the new motor in winter 2012 .
2013 winter I replaced my engine cradle "the mounts were going bad",new front and rear motor mounts,new rack in pinion......new coil packs etc....I have 11,000 miles on the motor.I have also replaced all brake lines,fuel lines ,gas tank,pump.....
Any thoughts would be great

You may need to see the real time data on that car... Can't even point you in the right direction.. Could be a handful of different things..
