Hello everyone! I'm Mike, and I just bought a 94 Silverado a week ago. It's been good until a couple days ago. Bad things started happening. While accelerating trying getting on the interstate (twice) while doing around 50 mph, the engine 'disconnected' from the transmission and revved like it was in neutral. Then, yesterday it started to jerk and jolt itself into second gear. Now, it shuts immediately off when I put it into any forward or reverse gear. It did it first at an intersection. I pushed it to where it was going down hill, started it, and put it in drive while rolling and it got me home. Any solutions? Hopefully, I can get an absolute so I don't have to throw parts at it. I suspect the torque converter, but I'd like a hard confirmation on that. I've put 750 miles on it in 7 days. Thanks! Mike.

 

More info: Original engine was replaced with a 5.7L TBI some time ago. It has around 175k on it. Truck has 255k. I'm not aware of any previous transmission work. I've checked vacuum hoses and all look good. There is one on top of the transmission that leads nowhere. ??
