Uggghhhh please help a newbie out. I have a 2000 Ranger 4.0 and had to changer the lower intake gasket due to coolant loss replaced the upper gasket and valve cover gaskets in the process. Got it all back together and now the auto tranny is shifting HARD into all gears. Before the gasket change out it had no problems. I've looked over my lines and plugs and don't see anything I missed. Vaccum leak maybe? HELP

 

I FIXED IT! A darn plug wasn't pushed all the way in on the intake..LOL shifts perfect now...WHEW

 

Good work
