need your help about speed cal for automatic

[jassyd8]

i just had my 4.10 gears put in today finally...and they said that the speed cal that i had wouldnt work for it...i called brothers performance who i ordered it from and they said they dont make one for an automatic...so i said why did you sell me it and they said they assumed i had a 5spd...anybody know a way for me to get the correct speed on my car? if so please let me know....

You have to get the computer re-flashed or get a chip. The problem is that the speedo uses one method of determining speed and the shift program in the computer uses a different vehicle speed sensor.

If I had an auto and changed the rear gears, I would use a device like this. http://superchip.com/html/products/ford/cars.htm

I just bought one for 339.00 and I thought that was a good deal. I would buy this right now at that price if I had not bought one last week. Thats the lowest price I have seen

I'm working with a seller on ebay for one at $260. He will have to order it, but they can be had for under $300 post as soon as you guys get them. I'm looking forward to buying mine!

You got the right information, you can't have a speedcal put on an automatic because there are two sensors on an auto, not just one like the 5spds.

The chip is a must, you should also get it to set new shift points along with the speedo correction.
