i've noticed lately that when i am cruising on a downhill slope doing 40mph, o/d off, and my foot off the gas, i get a bog around 2000 rpms. i'll just be coasting along at exactly 40mph and it will bounce up and down unless i hit the gas. what the heck could be causin this? it is so annoying if i can't speed up or slow down at the moment to get rid of the bog if i am driving at that speed.

 

same problem here man its the automagic trans, pm me if you get an answer
