As I was driving to work today, I noticed my van was shifting a bit odd.... Then, as I was in the middle of a busy intersection turning left, my van would barely accelerate, and finally reached a max speed of 17 mph. I quickly pulled into a parking lot, and shut off the engine. I tried restarting and trying again, but alas, it would accelerate, very slowly. It acted as if my brakes were on. I called a local transmission guy, and he has seemed honest, and the online reviews were high for him, but I am wanting to try and be somewhat informed before I make a decision on whether or not to fix it. It is a 1998 LXI, with 142,000 miles. At what point do I decide that it is not worth fixing? I do love this van, it's very convenient, decent shape, etc.... Any help would be GREATLY appreciated!!
