Sounds like it is stuck in 3rd... or in a failsafe mode.
Any warning lamps on?
Did you check all of the fuses on the car?
Since the engine was replaced recently, I would highly recommend taking a very long look at the wiring harness. Make sure all of the grounds at the back of the heads are in place.

You gotta fix the obvious things 1st.
Find out why the lamp is on and that just might give you a clue as to why the PCM is commanding max pressure and it is not operating correctly.
Try this right after you get the codes..... disconnect the battery for a few minutes in order to clear the memory. Then run it through the gears to see if it is a hard fault and go from there.

Brand new to this site Hi all im new to this site i mostly post on ls1.com ls1lt1.com..This thread is interesting because i have the exact same problem..i have a 94 firebird lt1..
Freshly rebuilt 4l60e with all the stronger internals and a 3500 stall...but the danm thing wont give me 1st gear and 4th..I think it wants to be in 3rd gear..but i can selct it in 2nd manually because of my shift kit I was told....
This Fail Safe mode sucks *** and i want to drive my car already....Im getting a scan today and hopefully it will shead some light on why its occuring...I will keep you posted as it may help you?
