Good evening,
My truck has a 2.8 liter v6 and a 700r4 and has been having problems recently.
This first happened in May when driving around 65-70mph on I-90 climbing the Appalachian mountains. The truck seemed to jerk back and forth like the transmission was disengaging and reengaging a couple of times a second. I slowed down to 40mph and assumed I was pushing the vehicle too hard for what it was, considering that the truck was filled with my college stuff and I was going up a steep incline at high speed.
This problem did not reoccur for several weeks, but eventually, it did at 65 on flat ground. Then, in the following weeks, it got progressively worse, happening at 55mph, then at 35-40mph. The jerking happens at these specific speeds regardless of how much throttle I'm using but always stops once i take my foot off the gas and the Jimmy slows down. I can no longer accelerate past 35-40 unless I'm going downhill, then, once I get past 40, I can accelerate freely until 55mph, and then it's the same deal.
I read some self-proclaimed transmission mechanic online say that it was a bad lockup solenoid, so I replaced that, but it made no difference. I then readjusted the T.V. cable, and it completely resolved the issue for about half a week, but then the problem came back in its entirety. I readjusted the T.V. cable a second time, and it didn't fix it, even temporarily.
On a side note, I had a mechanic flush the system right before my road trip back from college, where the issue originally occurred.
I'm desperate for a resolution to this as I need to drive 1300 miles back out to college in mid to late August, so all feedback is greatly appreciated. I'm also working like 60 hours a week right now, so I may be slow to respond, but thanks anyways.
