Hey Pat!
Hmm, the transmission was filled with a blended recipe of fluids,
given to me from a very reputable source - off the top of my head, I can't remember exactly what the mix was, but speaking with Matt, he's pretty confident that the problem with the 'box extends beyond whatever oil was used. I guess the exception to that theory may be if a bearing has failed, but again, this wasn't a completely inappropriate oil (like engine oil!) that was used, it was a blend of regular recommended grade oil, but mixed with an anti-shock oil (I think, again, I need to read back through my notes and remind myself).
I'm going to take my overalls up there tomorrow, and see if I can persuade Matt to start stripping the transmission while I'm there!!
The next question is, "do I upgrade my LSD while we're stripping the unit?" Obvious candidates are Wavetrac or Guard, or maybe just a rebuild of the stock unit. I suppose it depends on the condition of the LSD as it currently stands, and whether the economics stack up.
I once had an Auto Torque Biasing diff in a previous RWD car (made by Quaife, as it happens). It was a long time ago, but if memory serves, it felt quite snappy when traction did let go. Not sure whether an ATB or a true LSD upgrade would be the best route for a pure road hotrod. As said before, this car will not be going on track, so something hyper aggressive for smooth track surfaces is not going to be the right choice for Britains bumpy, oddly cambered public highway, not to mention I need something that if I get caught out in adverse weather (it's happened before...) it becomes an oversteering liability.
Having read a number of threads
like this one it looks like ATB's have a significantly shorter expected life than a good LSD; granted this statement by Paul Geary (ex Guard) and Matt Monson (Guard, present day) was in reference to track use, but even so, with hopefully the torque numbers we'll be pushing through it, I don't want to be pulling the unit out for rebuilds that often!
