First of all - my post thread title is misleading, sorry about that.
So for the past 3-4 k miles I was experiencing a shudder / jerking / kicking in the drivetrain. My truck has 148k miles, and I replaced the sparkplugs (again) at 134k miles so I did not expect the engine to be the source of the vibrations and problems. Also, there was no ECM codes, I could rev the engine smoothly in Park, and no misses or anyhing. Also, most of the time it would drive nicely, shifts are good, and everything was OK. The shuddering would be most evident, and sometimes violent at 1800rpm / 50mph going uphill. All these made me think (on top of other posts here) that my torque converter is going south.
I went to a tranny shop (they only do trannies and drivetrains) and when I said I have 06 Explorer v8, the owner responded right away "that's the first year of the 6 spd", so I knew the guy knows his business. When I told him my symptoms he said it could be TQ, but he would take it for a drive on a hwy with a SnapOn scenner hooked up to detect any slippage on tq. Also, he said that he only had four 6rxx trannies so far since they are pretty good transmissions, and the ones he replaced were high mileage ones. So I was going to come back to him for that.
Before that I decided I am going to take a last shot at the engine. I wanted to throw the code on ECM. So everyday whenever I was approaching a hill, I would let the rpm drop down, and the speed down, and then at the bottom of the hill tried to accelerate. Finally, after few days I got the code and it was 308.
Since I was still on original coils, I ordered set of Accel yellow coils 140033-8 (found a set for $ 233 on ebay), and set of new Autolite HT1 for $ 70. Last night I replaced them all (about an hour job), and the car runs like new. I tried the uphill trick to cause the misfire, but no, the engine run smooth like a butter.
This is just to confirm what another member Tojan19 went thru, also about to replace his TQ, when finaly he got a code for a misfire, and a new coil fixed it.
PS: I was quoted $ 400 for converter plus $ 700 labor, or 4500-5500 for the entire tranny.
