i have overfilled my atf fluid after installing my vb and cooler. when at a full stop and in drive 1st gear dosent catch untill i give it more gas and then it feels like the gear is engaging too fast and giving a jerk. could this be due to having too much atf? mabe too much line pressure from the added atf? how can i bleed off some atf? should i just drain a little from the plug in the pan?

any help or advice would be great

thanks
