Polyurethane tranny mount installed.
No pics cos I was absolutely covered in dirt, oil, bits of dead fox, and general filth.
Was going to do a before and after vid, but my footage from before that isn't drowned out by music is very limited and I've only been for a short drive round town.
Feel
Amazing. So much smoother. No resistance when trying to shift into 2nd (up and down).
Didn't get a chance to try 6th, so it will be interesting to see if it's helped at all.
Noise / Vibration
Fantastic. There is an increase in noise, but it's a lovely deep rumbly noise, like a V8 or a well executed exhaust leak.
There is the faintest hint of whine sometimes, particularly if you don't shift accurately and everything has to adjust speed, but it's barely noticeable.
Didn't notice any increase in vibrations and no new rattles, so that's a bonus.
I haven't gone overly hard, should be somewhere around 70A, but I kinda wish I'd gone a bit harder since it will settle down after a few hundred miles and I'll probably lose some of the new rumbly noises
