97 46re in a Ram 1500 Laramie
Trans problems (of course). Had a slipping problem and changed out the governor solenoid and switch. Ran great for about a month with a few hiccups. A little stutter here and there and some slight slipping. But the other day as I was cruising around, my rpm's went way up and I wasnt going any faster. Pulled over, checked fluid level and under the truck for possible leaks, nothing. Tried selecting all of the gears, nothing. Turned it off and was figuring a good way to blow it up without causing a forest fire, but I finally calmed down. Started it up, selected a gear, and off I went for about 500 yards. Pulled over, shut off, restarted, and off I went. Happpened out 5 or 6 times before I coasted into my driveway. After research the code PO740 (I think) I have determined that it is possibly the TCC and Overdrive solenoids. After looking at Youtube, I watched a vid about this problem and the guy was saying that it could be a broken part on top of the valve body some plate with a spring/plunger in it (can't find the vid again so the name of the parts is beyond me) Any input would be greatly appreciated. I;m contemplating dropping a chevy 327 and a 700 tranny in there but cab't find a adapter assy for the transfer case 
... HELP..
Looking forward to learning and sharing idea's and glad I found this. Hope this thread is ok for this section. Be gentle with me, I"m sensitive......RIIIIIIGHT
Have a great day.
p.s. After researching in this section I tried the "disconnect the 8 pin connector" and the tranny still slips. When in reverse and in neutral, I hear a metalic, squeel (can't really put it into words) type of noise. Hope this helps. Shooting from the hip - it sounds like a pump of solenoid problem. Thats why I'm here, to learn.
Will the pump make weird noises if the TCC Solenoid isnt working properly and still slip with the 8 pin connector disconnected??

All the electronics in the trans are disabled by unplugging that connector. If the trans still exhibits undesirable behavior, it's a mechanical problem. It *might* be just s dropped band anchor, or something equally as simple. Need to drop the pan to find out though.
