gmrulz4u Posted August 11, 2003 Report Posted August 11, 2003 If you read my post below, titled "Great! What just happened...", you'll know that I had a "shaky" engine since Saturday. Well, it was all fixed-up today, as it ended up just being an ignition wire that was touching my exhaust manifold. The wire was completely melted at one point and spark was shooting out of the crack and hitting the engine itself... Anyways, here's the part I need an explanation for: My tranny has had a harsh 1-2 upshift for months now...after my engine started mis-firing this past Saturday, my tranny started shifting PERFECTLY! But, I knew that as soon as my engine problem was fixed, my harsh 1-2 upshift would be back...and of course, it was!!! So, what the hell!!?? I don't understand why when my engine is mis-firing, and losing power, my transmission shifts awsome, but when my engine is firing on all cylinders, my tranny shifts poorly?? I was thinking of possibly vacuum problems or something...I believe a mis-fire causes lower vacuum, so maybe I should adjust my modulator to "turn down" the vacuum or something...I don't know!!?? Anyone?? THANKS! Quote
ShockTherapy Posted August 12, 2003 Report Posted August 12, 2003 i had this same problem with my regal, and yes, i would too like to know. Quote
Brian P Posted August 12, 2003 Report Posted August 12, 2003 vacuum, you probably had less vacuum. Get an adjustable tranny modulator Quote
AWeb80 Posted August 12, 2003 Report Posted August 12, 2003 adjustable tranny modulator That sounds like a line from "Dude Where's My Car" But seriously, where do you get one of those and what does it do? Quote
patgizz Posted August 12, 2003 Report Posted August 12, 2003 you get it at the parts store. i think most people buy them for a th350 Quote
Robby1870 Posted August 13, 2003 Report Posted August 13, 2003 Ask for one from a '90 Cutty Supreme with 3.1L, they were factory items then. And, the modulator will work on a TH400, if anyone is curious Robby Quote
Brian P Posted August 13, 2003 Report Posted August 13, 2003 Ask for one from a '90 Cutty Supreme with 3.1L, they were factory items then. Robby since when? Quote
Robby1870 Posted August 13, 2003 Report Posted August 13, 2003 Did I say factory?? I guess I had a brain fart.........maybe I should just say that if you ask for one from that you will get what you want. ...........Long Day.......................... Robby Quote
