Was driving from red light and when the truck went to grab 3rd gear, revs went up like it was put into neutral . Pulled over and truck went into 1st gear. Pulled out and would not shift out of 1st. Limped back to the house about 7 miles in 1st. Got to the driveway and put in reverse and it went into reverse a little harsh. Put into drive and would only go into 1st with a little throttle. About 1100 rpms. Shut truck off . Went out this morning put truck in reverse went in like normal put it in drive and took a couple of seconds later than usual and went into 1st. Heard slight ticking before it went into gear. Drove down the road shifted into 2nd then 3rd like normal drove that way for about a mile and a half.( Dirt road) Got on to paved road and came to stop. Started out in 1st into 2nd and before it could shift started slipping and it dropped back into 1st. Turned around and it shifted like normal back home. Was very easy on the throttle. Four days prior to this happening I replaced the plugs and coil packs with ruthenium NGK plugs and NGK coil packs. (Bosh iridium was from the factory)Truck ran fine for four days then tranny problems. Was going to do fluid/filter change a couple of days ago but got up in something else. Talked to a buddy of mine that is pretty familiar with these new Rams and he said to put the old coil packs back in before doing anything else. (The resistance from the new coil packs and plugs might be messing with the computers jiving) I'm old skool but I guess anything is possible with these damn computer controlled things. I was going to start with the fluid change and if that didn't fix it was going to go with pressure sensor transducer and speed sensors. Any tranny gurus on here have any thoughts?
