Ok the answers are there some of them in the codes
the_" P0123 - Throttle Position (TP) Sensor Circuit High Voltage" would affect everything from line presure to shift points.
The other code is not trans related.
You need to repair the TPS circuit and then get a scanner on there and watch whats being comanded by the PCM in data gear wise.

o so it should be all set then. speartech said that all the wires were right on and all work right. he tested the PCM and harness on his motor at the shop. so now im waiting for it to come in and i can install it.
so if the tranny is good and the wire harness is good then what could it be?? the answer is there some where!!!!!!

Turn the key on, mat the pedal with a voltmeter
on the TPS output (to ground) and read it. If
you are over 4.75V it will set the code and some
trans functions will act funny.
