It isn't Tramp.

In shell-mode, always the *local* history file is read:

--8<---------------cut here---------------start------------->8---
      (setq comint-input-ring-file-name
            (or (getenv "HISTFILE")
                (cond ((string-equal shell "bash") "~/.bash_history")
                      ((string-equal shell "ksh") "~/.sh_history")
                      (t "~/.history"))))
--8<---------------cut here---------------end--------------->8---

The code above must be improved to read the *remote* history
file. Something like this (not tested):

--8<---------------cut here---------------start------------->8---
      (setq comint-input-ring-file-name
            (concat
              (file-remote-p default-directory)
              (or (and (not (file-remote-p default-directory ))
                       (getenv "HISTFILE"))
                  (cond ((string-equal shell "bash") "~/.bash_history")
                        ((string-equal shell "ksh") "~/.sh_history")
                        (t "~/.history")))))
--8<---------------cut here---------------end--------------->8---
