haha, Yes, GM Warranties are THE best. I lost my 4L60 with about 7200 miles on the clock. Replaced; no questions asked, no $$$. lol
Of course i neglected to mention anything I did.
Btw, my front main was leaking too. The whole crank sensor was constantly wet with oil at all times, as well as the surrounding conduit and rack pinion stuff. Coincidence?
Glad to hear your ride is back in action.
...Now get out there and run 12's
