Look @ the TR Code in the VIN Sticker on your 98. "U"=4R70W "E"=E4OD
Look @ the Identification Sticker located on the Left Side of the Tranny case.
The 2nd set of code is the Tranny Model.

Did you reset the PCM? It could be applying the old settings learned from the old tranny.
After accelerating using 1st gear can you feel the engine brake when you release the throttle? Can you hear the whine noise?
What happens if the gear is in Drive @ WOT?
Try shifting it manually, accelerate starting from the 1st gear, shift it to 2nd, shift it to drive.

Does the Engine RPM increase a little when you tap on the brake? Do Engine RPM decrease about 5 secs. after releasing the brakes?

Yes the engine rpm increases when tapping brake pedal. Decreases 5 seconds after released

Since the Tranny is trying to ship to another gear the TPS is working.
If it's overheating the pump is damage. When mating the Engine to the Transmission if the Torque Converter is not seated properly it will hit the Flex Plate..
If the Tranny is 4R70W
Even with the transmission connector Disconnected, some gear ranges are still available in manual ranges because the circuits opened provide redundant passages to shift valves and apply components.
These passages are independent of the solenoid-controlled passages
It will not Overheat if the pump is working.
