Hmm. Have you checked the driveline angle at all? Could be sitting up a smidge too high at the tail, and anything would help.
Looking at the transmission mount bolts I really don’t thing the transmission is any further back than mine, not more than a 1/2” for sure. I don’t have that same side shot but you can see how far back the shifter sits, and from the bottom you can see if the transmission was another 1/2” back that next bolt on the shift cover would be behind the crossmember…
