Tranny Malfunction, lost OD, 3rd gear
Last night out of the blue at 45 mph in overdrive my truck appeared to go into neutral, no warning, no engine light. Shifted to drive and did fine until I drove down the interstate. Went back into OD and 1 mile later lost OD again, engine light comes on, drop to drive, loose drive the next mile. Exit and shifts weirdly from then on, starts in a higher gear etc. Fluid clean and full. Drive it this am, runs like a champ, engine light still on. Code reads PO758 solenoid,2nd 3rd. Question, fluke? Wait for it to happen again? Take to shop and have the never changed fluid exchanged, 91k, and have the guy look at it? Input please.

When you say it ran like a champ this morning, do you mean all four gears worked OK?When you hear hoofbeats, look for horses not zebras.

Well, the mechanicals of the transmission are ok. At least for a while.
