I have a 4500 in my 93 and it's going strong at 150k. I did change fluid in it at 100 just because it seemed like a good interval.
It's a good transmission. It has always had a touch of synchro "bite" on the 1-2 upshift if you're being speedy, but that's minor and avoidable.

Is your first gear so low that you don't usually use it?
