Re: 4.0 jerking proble
I haven't yet replaced the pigtail to the IAT sensor but I think that isn't the cause of the excessive jerking. I belive it's the transmission slipping and badly too. It slips in all gears and when I checked the fluid it was at the bottom of the dipstick. I made sure it was at operating temp by driving it for a few miles, and followed the steps i found on a forum, setting it on a level surface, putting the parking break on, shifting the transmission from park, reverse, nuetral, drive, and, and 1st, then back to nuetral. Turns out the fluid was about a quart and a quater low. I added a quart of oil with no resolve to the slipping.
Any more help would be greatly appreciated.
