Missing or slipping? Help guys

[BryanH]

I just walked in the door from driving a consistent 60-64 mph for 550 miles. No load just truck. 70 miles from home my truck started jerking when you gave it a little on the hills. I though maybe the long boring 60mph might have coked up the vgt so I nailed it, No help.
The motor seems smooth, No codes, I can't tell if the trans is slipping? EGR valve clogged, Injector, Torque converter, Or maybe fuel delivery, Maybe the pump (ficm) is getting old, 162,000. From a stop it's normal, It's when your running 60mph and give it a little or nothing (a couple times) it jerks or misses would be a better description.
Oil was brown and full, Tranny fluid was red and full I could keep my hand on the trans pan and diff cover.

I am at a freak in loss here. Any and I mean any suggestions will be appreciated.

Sounds pretty much like what mine did before my trans took a dump. Almost certain it was the TC slipping.

What was your tranny temps like before your trans failed?


I sometimes wonder if mine is slipping, but my trans stays below 160 degrees regardless of city or highway.

Didn't have a gauge when I first noticed, but then got one and I would have the issue even at temps like 160 but that doesn't mean it didn't real hot before I got the gauge and that started the whole thing.

It felt like I was hitting a tiny patch of ice for just a split second. Then it eventually turned into that plus the TC locking and unlocking while doing 70mph or so.

I never noticed it driving around town or anything, only on mountains. I did a TC lockup switch which solved that problem, and I milked the trans longer than I probably would have otherwise.
