Drove to work today, SES light came on. Just had new exhaust manifold put on last week, and SES light came on because they forgot to put my MAF sensor back into the cold air intake. No big deal right. Well my SES light came on today, so I thought it might be the MAF sensor again. It was fine so I just drove along. Well, coming home tonight from work, driving 70 on the turnpike, I went to downshift to pass some cars and go up a hill, and the RPM's just soar way up and I get virtually no response at all. Like it was in neutral and you hit the gas when driving. But as I throttled in a bit more, the torque converter would lock up and propel me forward, albeit seemingly in 2nd gear, but once I let off the throttle, the RPM's went back down to normal, but in order to keep the truck moving until I could pull off, the RPM's were soaring in order to get something in the drivetrain moving.
So I pull off, and I smell a burning smell, which I kinda thought might just be the new exhaust manifold breaking in. No smoke or fluid leaks and the engine was idling perfectly normal. Only thing I noticed was the belt tensioner assembly was wiggling a bit as the serpentine belt spun while in idle. (Not sure if it is normal for it to pivot in place slightly as the belt runs or not).
Anyway, I turn the truck off, then on again, engine is perfectly fine. I shift into D and drive home, same problem going on. So I come to a stop sign, and I press the gas, and the drivetrain engages normally, but it won't upshift. I had to hit the throttle til about 5k RPM's for the torque converter to lock up and it finally shifted, a very harsh shift. While I'm driving, I can hear metallic grinding noise, very very faintly coming from below me.
When I pull into my driveway, I shift down into 3rd, 2nd, 1st. The initial shift down from D into 3 required more than normal effort. Then I put it in 1st then manually shifted into 2nd as I got going a little bit, and a very rough shift took place, and it was shifting immediately instead of waiting to sync itself like normal. Almost felt like it was shifting as if it were in Low Range. Neutral worked normally, as did reverse and park.
So, what's the prognosis? Fried transmission? Taking it to a shop in the morning.
