For the past few months I've been having a fairly regular problem with my transmission. When cruising around 30 to 45 mph the transmission seems to shift up a gear too high and the motor lugs. If I come to a hill or what to speed up and I give it gas it downshifts sometimes and then upshifts too early and bounces back and forth. Other times it stays locked in gear and won't downshift unless I really stomp on the gas. When it's lugging if I take my foot off the gas or brake the transmission stays locked in gear, really brings down the RPM's, almost stalls and then there's a clunk and it shifts down. Last week it stalled twice (once with 4X4 on, once in 2 wheel) instead of downshifting. And sometimes it operates like nothing is wrong.
When I accelerate it usually has no problems, but sometimes I get upshift/downshift bounce for awhile around 35-45mph and rarely at 50-60mph and is fine at speeds above 65.
If I'm going to have to slow down from 30-45 to stop at a light I can shift it manually into neutral or 2nd or 1st and there is no problem with disengagement. I can start it in 1st and shift into 2nd and run it with no problems.
I have checked the vacuum lines, replaced the vacuum modulator, have no fluid leaks, no idiot lights, and seems to be independent of temperature - happens when the transmission is hot, cold, whatever.
Any ideas/help with what's going wrong would be greatly appreciated!
