4l80e problem and speedo,
hi folks, new to fifech and the forum. I've just bought a truck with ultimate ls , its a 6.0 with 4l80e,
I'm having a few issues it has not been fitted well, so i'm going through it, but have no experence of fitech,
first problem, 4l80e, i cant get a speed reading out of it, i have checked and double checked all the connections and settings,
the dash reads speed but not the procal, i reads as many threads as i can and tried changing the speed correction to 400 and now have a speed reading to the procal, is this normal, and can i change it from 400 to try to get a correct wheel speeed?
second question, i have a dakota digital dash, i seem to get interferance to the speedo, some times its fine other times it jumps ut to 30 to 60 mph when its put into gear not moving,
any ideas or help would be geat,
many thanks Jason.
