When I bought my car the kick down/passing gear was not working due to aftermarket 4 barrel and original linkage not attached properly. I added a Lokar linkage cable to fix the issue. I haven't been able to take the car outside of my neighborhood yet. Because I need to fix my mystery turn signal problems. The neighborhood driving doesnt allow me to get over 35 mph because of the very short stretches between intersections and side streets. And its a neighborhood, lol ! Regardless, I thought the tranny should kick down to passing gear if I stomped on it for 2 or 3 hundred feet. Well, it doesn't. I know without a doubt the cable is hooked up right and I installed a return spring on the transmission end too. Also verified it should be doing what it needs to with throttle linkage, etc. Do I need more speed, more time, higher rpm's and a longer stretch of road ? I know I can check by doing so eventually. My point is, is this normal ? Does the pump need more time to cause it to kickdown into 2nd from Drive ? I was thinking it should only take a couple of seconds if the pedal was to the floor. I have a 360 engine and 904 auto tranny. The transmission has no problems.
