I am having a couple issues with my 94 Corvette with Auto Transmission with 107k miles...any suggestions would be much appreciated. First, when I am coming to a stop, from like 2 mph to full stop, I am getting like a clunking that sounds and feels like it is coming from behind me and to the right (from rear middle of the car). It does Not do this if I shift into neutral b4 I get to low speeds. The second problem is, I got caught in a very heavy rain last weekend, and the digital speedometer area started blinking off and on about once or twice per second, and the "idiot light" panel lit up like a Christmas tree. The car started sputtering but never stalled out...it was almost if it was turning itself off and on repeatedly. I pulled over under a canopy, and waited out the brief but intense downpour, and its been fine ever since (about 100 miles), but it has only been driven in nice weather since. I checked the battery connections (and that's about it) and they were tight and clean.
