Ok, 2003 GMC D/A...on the dash it shows D 3 2 1, but I have counted the shifts many times now and it shifts 5 times. The last shift is at about 55mph and 2k rpms. Also 2nd and 3rd are really close. Is it possible someone has swapped it? How can I tell? Thanks in advance

You have a 5 speed, you might be counting the torque convertor lock up.

You can have a kit to put in a 6 speed valve body, but I highly doubt that's the case.

If you get an Edge Insight CTS you can monitor your gear and TC lockup.

It's the torque converter locking up. Feels just like an extra shift.

Call up Mike L @ Inglewood Transmission (He's a vendor on here) and ask him who a good local builder is, I don't know anybody in TN.
