HEY for the record this is not a stupid question. i have a 88 lx 302 aod trans with 4:10 gears and a shift kit. why would my car shift at 5k?..i know on the tach it goes yellow at 5k then red near 6k but are the aods meant to shift so early or is it tuned from the original owner?..will the kit make it shift early? thanks
