Slight & brief thumping ?????

Driving yesterday and noticed some thumping right under the center console, for only a brief moment while accelerating in 3rd gear from 1800 to 2000 rpm's. This is the only time it does this. No thumping during decel or at any other time.

ZF Transmission is in very good shape and Iis original to the car; I replaced the shift solenoids, sleeves & bumper maybe 10,000 miles ago.

Car has 184,000 miles.

Guibo or flex discs & center bearing are original

Transmission mounts are rogue engineering and might have 35,000 miles on them max.

I'm thinking of replacing both flex discs & the center bearing

Thoughts ???
