Bucking in 1st gear
I drove to buy some tiedowns today (about 6 mile round trip) and stopped to buy some groceries about a mile from home. I backed out of the parking spot and when I released the clutch to go forward, the truck started bucking. I thought I had mistakenly put it in third gear, and made sure it was in 1st and tried again. The bucking continued, so I treated it like I was in third gear and gave it more gas. Once I was moving, there was no problem. It runs, it shifts fine, there were no noises - before, during, or after. The last two blocks to my house there is a left turn and a hill. I pressed it up the hill in second gear, and couldn't detect any clutch slippage. Although the clutch engaged in reverse out of the parking spot fine, I drove past the driveway and backed up and there was a bit of bucking there as well. But every time I try in first it bucks. I have searched for similar M5OD/Ranger 5-speed problems for at least three hours, and get nothing. A few people here reported bucking around 50mph and it seemed to be ignition/ fuel control related. I looked at the transmission with a flashlight and there is some minor oily discharge on the lower back of the case, but no drips on the driveway. I hooked up the code reader, and no codes. I am honestly stumped as to what to try next other than go drive it tomorrow. I did see a suggestion in one post that the slave cylinder could be dripping brake fluid onto the disc. Is there anyway to determine this without dropping the transmission? Am I wasting time looking at the drivetrain?
