Plan to run Rubicon but trans is starting to slip...

Believe it or not, my wife has decided that she wants to conquer the Rubicon trail for our anniversary. Yes that's right folks, I'll say it again...for our ANIVERSARY! I know I couldn't beleive it myself. Ya see, she thinks that since its in California it will be fun and cool, like maybe Monterray bay or something like that. If course it will be way fun and cool, just not anything like a beach and more like 10,000 feet above sea level in the high Sierras. I no doubt will be on cloud nine and giddy as a scool boy. I hope she doesn't do any reasearch about the famous trail and find out what she's really in store for. So that's the good news. Now for the bad. Not only am I still trying to fix the Tacoma and build a serious trail bumper on the front...now the Blazer, which has been my current daily driver for that last 2-months, transmission is starting to slip. Tonight as a matter of fact, it didn't shift into third gear...it just revved like it was in nuetral. It eventually slipped in but I know its only going to get worse. So probably about $1000 and another two months later that will be fixed and maybe...just maybe we'll be able to hit the Rubicon and tell of our eventful adventure!
