OK I HAVE RECENTLY PUT A REBUILT 4L60E IN MY 94 Z28. ITS GOT A SHIFT KIT AND THE TORX BIT SCREW SCREWED IN A QTR OF TURN. THE PROBLEM IS THAT IVE BEEN NOTICING THAT WHEN I FLOOR IT OR GIVE IT 3/4 GAS I NOTICED THAT IT SEEMS TO BE SLIPPING A LITTLE BIT FOR LIKE 2 OR 3 SECONDS AND THEN GRABS.ITS NOT BAD AND ITS BARELY EVEN NOTICABLE I THINK MAINLY CUZ I HAVE A LOOSE V6 CONVERTER AND USUALLY NOTICE IT ON THE HIGHWAY WHEN IT KICKSDOWN INTO A LOWER GEAR.I DONT WANT TO HAVE PROBLEMS DOWN THE LINE IF IT COULDVE BEEN AVOIDABLE. ANY IDEAS? MAYBE NOT ENOUGH LINE PRESSURE? I NEED TO GET A GUAGE TO CHECK THIS. IM STUMPED.

 

Are you getting any codes, Do the shifts feel firm ?
