Shifting Hard
I have a 91 F150 2x4 302 with E4OD trans.
The problem I am having is slamming between gears or when I let off the throttle.
I have pulled the codes. No codes for the KOEO. I receive code 111. I do receive stored memory codes 327 DPFE or EVP circuit below minimum voltage of 0.2 volts. and 328 EVP circuit below minimum voltage of 0.24 volts.
The only code for the KOER is 311 Thermactor air system inoperative (right side).
The engine idles ruff but seems to run well at other speeds.
Would any of these fault codes cause the hard shifting? The shifting problems started when a new short block was installed
