Reply to "ZF won't shift when cold?"

I've also run into one Pantera that would not shift into reverse when a Hall aluminum gate-replacement was mounted. I fiddled with the linkage for a while but the difficulty was finally resolved by bevelling the inside edge of the dog-leg gate between reverse and 1st at a 45 degree angle, so the stick could be laid over far enough to actuate reverse gear! A quick dab of flat black paint on the new bevel and the (brand-new) part looked new again.
