3k rpm issue
Howdy
Got a fellow dodge owner that has a nice 99 ram 1500 with the 360. Ive been helping him out since day 1 when he bought the truck. Recently he was on the interstate when there was knocking noise coming from the engine compartment around 3k rpms. He then told me when he was in overdrive the rpms bounced around above and below 3k rpms and the check engine light was flashing. I grabbed my code reader and we went on the interstate with no luck of the engine light flashing. I was wondering what this might be. Only happens when engine is under load. Doesnt happen in neutral when engine is revved. Any ideas?

No idea what the knocking noise you hear is, would almost have to record it so we can have a listen here. It remains to be seen if that OD solenoid is making that noise until we can get more information.

At 3000 rpm, OD is not on. If rpm is that high it would run about 65 t0 70 in third. In OD it should be 2100 to 2200 rpm for 70 mph. Knocking could be TCC locking and unlocking. Need a good scanner to read tranny and see what is going on. Also chec TV cable adjustment to make sure it is right.
And +1 on knocking.....kind of have to hear it.
