Car seems to run like a dream but I have a problem with my trans shifting too soon from 1st to 2nd gear. Just as I start building good boost under 3/4 or WOT the car will shift into second. I have a peg leg so the tire will just start to spin or break loose then she will hit second sliding the tire for about 30 feet, drives me crazy. I feel like I need a few seconds more boost before I hit second. The tranny is stock 63k miles never opened. Not a TCC issue more of a TV cable issue. I have adjusted it to factory specs with same results. Any thoughts?
