| Right now 1-2 shift takes about 0.68 - 0.7 seconds and I'd like to see .3 taken off that time before drag day. What kit can I get that speeds up only 1-2 shift? 2-3, as well as 3-4 are quick enough and don't need any modification. |

If you already have a trans that has higher mileage on it, & has a long 1-2 shift you might be out of luck. If the band is already cooked your going to have a up-hill battle.
A shift-kit should help, as well as bringing up the line pressure (which can be achieved several ways), a trans flush is a good idea too. As far as servos go you need at least the Corvette servo. |

| Al, Trans has 119k on it, has increased line pressure through a tune. 4.11s help take the load off it a bit. 2-3 and 3-4 shift great but it's just my 1-2. Car has the vette servo in it. I was just thinking of shimming the spring in the 1-2 accumulator to acheive a quicker shift. Ideally I'd like to have it done for drag day  |

| Replace the trans with one that doesn't have 120k. |

| Ok gotcha. So let me ask you this...does removing accumulation hurt the transmission/hard parts? Am I going to be damaging anything @ part throttle with accumulation deleted altogether? I think I remember reading it's simply put there in the first place so the customer has an 'enjoyable' shift. |
