Hello, This is my first post on this forum. I picked up a 1987 Electra Estate Wagon with a th200-4r from a friend who just wanted it out of his garage. I needed a car, and he was kind enough to give and help me repair his old wagon. The tailshaft bushing had been chowdered up, and before we realized we could buy a puller tool on ebay we already had the transmission out of the car. fast forward a week, and we get it back in, connect up all the lines, tv cable, ect with a new bushing, seals, and filter. I drive the wagon home and have a week of blissful comfortable driving. Just tonight though, I tried to drive back to see my folks in St. Louis (I live in Indiana) and I get about 100 miles there when the car starts making a horrible growling noise. At first I thought it was rear end noise and moved to get off the highway, but am between exits. by the time I get to the next exit, The noise has gotten worse and is accompanied by a terrible vibration. when exiting the ramp, I hear what sounds like a snap and the noise and vibration go away. The car drives perfectly again for a few miles with the exception of the speedo, which is now swinging anywhere from 80 to 45 mph at highway speed. suddenly I hear anouther popping noise and the speedo reads nothing and the trans seems to be disconnected, but it gets weirder. When coming to a stop, I realize that the transmission hasn't stopped working, but just wont shift out of first gear. the speedo is still dead but the car idles and creeps like normal. I found out that if I baby the throttle after starting the car and putting it in gear that the speedo will come to life (swinging the needle wildly) and the growl and rumble will return. applying light throttle will get the car into second, and third gear seems to work whenever it feels like it. if I make it into fourth then I win and the car stays in fourth. (although the vibration and growling are still present. I'd really like to keep this wagon, but will not be too broken up about it if the trans is completely destroyed. (The only payment my friend asked for was a twinkie and cost of parts). I've searched around on google and can't find anyone who has had the same issue.
