Does anyone have experience with a Speed Cal? What do you think of it?
Aric ordered a Speed Cal for The Mark, to try and dial in the transmission's WOT shifting issue it has. I only notice this at the drag strip. Not really a street problem since all the drama happens during WOT, and I am never in it long enough on the street to notice it.
I have 410 gears, and two different size tires on the car - 255/35/18 front t1r street tires and 265/40/18 rear drag radials. I have the white 410 speedo gear in the car now, but Aric is going to put back the stock 327 speedo gear in the car when he tries the Speed Cal.
Lately what happens at the track is the 1-2 shift is fine around 7150 rpm, then not sure about the rpm, but it short shifts the 2-3, then down shifts back to 2nd and takes it up to about 7k like it should and then goes to 3rd. He currently has the torque converter unlocked during WOT until he can figure out the shifting.
Whatever is going on, it messes with the traction control and the speedometer inside the car. After a run, I have a check traction control error on the message center, and the speedometer needle bounces up and down - 20mph range, at whatever speed I go. Turning the car off and back on fixes that.
lol He has never had this problem with any of the cars he has built. Just mine... So, I think it might have something to do with all the extra electronic crap Lincoln put in this car, and it does not like all the changes made and is fighting Aric to the bitter end.
Anyone else have this kind of issue? Jerry W. has looked at the trans tune, and all is good there, so this is like a last resort to see if it will go away.
