I'm not sure of your question. It should go from 2nd to 3rd then to OD. When was the last time you changed fluid and filter in your tranny?
I just had the same problem on my 2001 ford f-150 and it was the Tps unit. I dont know if they are the same on differant years.

700R-4 if it's an overdrive transmission. You can tell if it's a 4 speed overdrive by the "D" on the shift indicator. Overdrives have a circle around the "D". Non-overdrives (3 speed automatic) don't have the circle around the "D". If it's just a 3 speed automatic, it's a Turbo Hydramatic 400, commonly called a Turbo 400 or simply 400.
If it's a manual transmission, you'll be talking about putting an SM465 to replace an NV3500 or NV4500... I'd be doing the opposite swap, personally, as the SM465 is a direct drive transmission with no overdrive gear. It can be done.. you'd just have to use the NV bell housing, and you might have to replace driveshafts with ones fitted for the new setup.More the same with the automatic transmission... there's no reason to replace an overdrive 700R4 with a direct drive TH350.
