Shudder in 3rd 1800-2200rpm

[MikkiJayne]

Short of very expensive chemical analysis there's not really any way to tell whats in it, and I've only used genuine fluid so have never seen any red variants of it to compare. The genuine stuff has a distinctive smell too, whereas this red stuff is has no distinguishing features. I'll just re-fill with genuine and go from there.

Its rather odd that the TC was supposedly rebuilt at the same time as the gearbox and has failed after only a couple of years.
