That mileage isn't that high really Ash - my last 740 had about 235000 miles (380000km ish), my Jeep had 245000 (395000km ish) and both responded well - no need for gap filler to "beef" it out!

I've used this trick to "cure" ticking hydraulic followers previously in early Mazda 12 valve engines (notorious for it). Again, high km's but no harm and did the trick.

When you also consider that some manufacturers including Rover and Volvo changed the service specs of certain manual gearboxes so ATF is used instead of engine oil then ATF can't be that bad as a lubricant anyway. I believe (though may be wrong) this was to improve cold shifting characteristics because of the better friction reducers in the ATF - i've heard/seen differing reports on how effective it is at that but the majority of reports have been favourable.
