Try adjusting the Modulator, even though it is for hard or soft shifting of Tranny but I found it to be effecting the pick up of the car. I would assume your car was running Ok before the Tranny chnage, so may be new tranny need adjustment.
Is it a new tranny or rebuild or used?
Did you trid changing the Fuel filter?
I hope it help. Keep us posted.
