1st thing to do is test the system for codes, the problem is most likely a failed or stuck shift solenoid indside the trans, have you ever serviced the trans, sometimes a fluid and filter cahnge will cure these kinds of issues.

Hello, The adjust of your t/v cable, not kickdown cable, and the operation of the vacuum controller at the rear of injection pump, and the modulator, is critical for this car to get a good shift.
Put you cable back on, adjust it so that when you have wide open throttle, the cable does not have any slack. Check the black vacuum line by the oil filter housing that goes to the modulator to see if it has vacuum. It should have about 10-15" vacuum and as you increase engine speed it should drop. If you get close to this, the trans should shift ok. If you cannot get vacuum at the modulator line, you need to ck vacuum supply, valve at rear of injection pump, hose routing, etc.
If the B2 piston failed, it would be difficult to move car or slip badly. Also, take into mind that at the bottom of your accelerator pedal stroke is a kickdown switch.
If you accomplish what I instructed, you will probably get a decent shift.

1st and 2nd shift solenoids has sediment causing them to stick.or you got damage leaking seals. it might help if you put a little transmedic in transmission dont over fill. if your valve body full of sediment it causing valve in valve body to stick.this might help still might have to go in transmission.

The EMC detected and problem so it's in limp mode, As long as it's in limp mode the 4th and OD will not activate. Take care not to burn up the transmission by running it hard while your in the limp mode.
Your going to have to get the truck scanned to clear any codes and why there are DTC codes. Auto Zone scan for free and most auto shops charge $10.00 to $20.00 to scan sine they want the business.
If you want to clear the codes your self you can put the ignition to the run position and pull the ECM (Batt) fuse out for 20 sec and place it back in then start the truck. It may stall but let it, just start it again and this would have cleared all the DTC code history.
The transmission should be running fine unless there is a problem and the service engine light will be on again and you'll be in limp mode still with an updated DTC in the ECM.
Good luck and hope this helps.

Well, there could be several possible problems. It is not uncommon to have a little harder shifting after a fluid change for a period if the system was low prior to the change however, If you had the fluid changed using one of those reverse flush machines I see the problem getting worse. Most stations want to use the back flush system to do a fluid change now days. That is because the newer model vehicle have a metal filter screen which is re-usable and is designed at the factory to use Synthetic Fluid. In the older model vehicles, 2000 to 2005, manufacturers where still mixing the types of filters that were being used. This model has a standard filter that model uses the newer filter. If you went to Jiffy Lube and didn't specify you wanted a regular Fluid and Filter change they hooked it to the machine and charged $140+ for the job. A regular Filter and fluid change with regular fluid would have run about $50. Every time, and I mean Every time, I have had a fluid change using that back flush machine on a vehicle within 6 months I have had to have the Transmission repaired at a shop. If you didn't have the fluid changed using that backflush machine then your problem is just adjustment to the new fluid being at the proper level. If you did, start saving for a Transmission rebuild at a shop, it's not far away.
