I've been laid up due to an injury and have not been able to do any thing with the car. Hope to be back at it soon and thanks for asking.

Ok, I'm recovered and back at it again! As a refresher, my problem is that when I place my shifter in the drive position it starts out in second gear and shifts to third. When I place the shifter in the second gear position it starts in first, shifts into second and then into third. It seems the "drive and second" position is backwards. It was suggested that I get the number off the transimission and post it so that maybe someone can tell me if it is a C4 transmission or something else. Here is the number which was on the passenger side of the tranny, on a round looking plate that had a large letter "A" above the number. C6AP-7D027- C or 6 (couldn't make out the last digit for sure). Does this number mean anything to any of you??? Thanks for the help.

Hey Teddy,
The numbers you listed are from the servo (round looking plate). Try to locate the numbers on the drivers side near the shifting mechanism. Í think they'll be more helpful. Also, there is much info on this link... http://www.mustangandfords.com/techa...tailshaft.html

For example, the numbers on drivers side of my C4 are D4DP-7006-AA, which, according to the link above would indicate my trans is a 1971-79 but I don't know how to decipher much more than that from these numbers.

If the numbers on the drivers side of yours start with "C4, C5 or C6" then it's probably the "Dual range" transmission that would have the shifting pattern you've described.

Geez, I hope that helps a little. Maybe someone else with far more knowlege than me will chime in here......LOL

Thanks RandyR. I didn't see any other numbers but I will look again where you mentioned. Thanks for the input.
