Hello,
Seems all my post here lately have been due to issues, and the help here has been great so i'm back. I have searched all around and found a post about the issue I am having but can not find it again.
2012 Jeep JKU
4.88s, 35s, Gobi Stealth rack (To give you an idea of my rolling resistance)
Auto, 95,000 miles
I was NOT towing anything just the Jeep
So took a road trip from Virginia to Georgia, the first half of the trip went great, on the return some issues started. Average high speed of 80-85. Stopped for gas and the Jeep was very sluggish to pull forward, engine RPM came up to about 2700 rpm before it would even move. I assumed it was because I was on a bit of an incline back tires were in a rut, pulled up to the pump got gas. Left the station all seemed well, transmission acted normal. Got on the highway and went over a bridge had a slight dip in the road and on came the CEL. This was about 8pm in S.C. on a Sunday so no way to get the code read. Fuel mileage dropped to about 6mpg, I got around 150 miles to the tank. Assumed it was bad gas possibly due to the flooding from the hurricane, ran it till the low fuel light came on and then some more, stopped to fill it up added fuel treatment and water remover gassed up. Transmission was acting up again, and was putting off a lot of heat could feel it through the console the bottle of water in the cup holder was even to hot to drink. Probably a bad idea but that time of night but me and the wife had to be at work Monday morning so I pushed on lightly. Keeping the speed lower 70ish which is the posted limit. Looking back now the Jeep would not down shift going up hill, so after the fill up the MPG returned to around 13 which is normal for mine on the highway. CEL stayed on, Jeep handled completely normal. Made it home and parked it, this evening after work I was going to take it up the road to the shop have the CEL read and the Jeep will NOT shift out of first gear. I let the RPM get up to about 4500 and let off, using the shiftier trying to manually shift will not do anything. Display continues to read D and not allow you to manual shift it. Also this evening when I started it and shifted from park to reverse to back out it was a very hard shift like you were on a hill, went to neutral and drive and it was a very hard shift. that is when I made an attempt at taking it to the shop and it would not shift.
Fluid is good, not low, not high, not burnt I changed it 7-8 months ago. No leaks.
Anyone have any idea? Sounds like it has to be electrical IMO, mainly because you can not get it to manual go from drive to 1 even at a full stop.
