Hey guys,
So I have a 2004 silverado 1500 and i decided to put the corvette servo in the tranny because the 1-2 shift has been a little hard for years now. anyways, i put the servo in, having done no previous transmission work at all, and i've been driving it around for a week now. the 1-2 shift is absolutely perfect now. but i noticed that when i really drop the hammer on it, the 2-3 shift is very wierd. it'll get up over 5000 rpm and just sorta flutter there for about 5 seconds before shifting. it doesnt spike in rpm or anything, just kinda flutters up and down maybe a 100 or so before it shifts. did i put it in wrong or is the fluid level too low? everything else is perfect as far as shifts.

trans might be getting worn, but first thing i'd do is check the level and try to add about 1/4 to 1/2 qt over the full mark...usually helps on high rpm 2-3 shifts.... make sure not to go over 1 quart

My buddies escalade does the same thing with his hypertech programmer installed. Holds in that gear for a few seconds and fluctuates at high rpm before banging the next gear, and sometimes you even have to lift off the throttle for it to shift. Weird shiat.

yea, it turns out it was just a little too low on oil. i put about a 1/4 quart in it and it's perfect now.
