I have a 96 Impala SS that the tranny just went out in. I went and got a re-man tranny but it isnt shifting right. I hooked up a snap-on diag. scanner to see if it had any info to my problem and the only thing that I can see is that the tranny line pressure is low. After flushing out the tranny cooler and hooking up an intercepter (its supposed to raise line pressure) the problem still remains. I'm no expert on tranny's by any means but the only other thing that I can think of that is left is the computer, I read somewhere that it controls tranny line pressure. If anyone has any insight to this Thank you in advance.
