My 03 T-bird had transmission rebuilt and still has harsh shifting. Transmission shop said problem was PCM now and not the transmission. Went through 4 different rebuilt PCM (can't find a new one) and still have harsh shifting and now E shows up instead of D5 when shifting. Transmission shop continues to state that this is a common problem and it is the PCM. Two different online PCM computer rebuilders say the PCM's are fine. Any suggestions? Thanks in advance.
