post #67 in that thread specifically mentions the cruise control/transmission hunting
I've installed JetTech's solution from that thread, and as far as I can tell, my issue with the transmission hunting on downhills has been just about fully resolved. (it's hard to tell-- I live in florida, near the beach. No hills). The improvement in overall handling from those spring helpers is tremendous.
