Theres a Device That monitors the out put Shaft on the Auto, I forget what it is called. My galant had the EXACT same problem. and that is what it is. DO NOT DRIVE it like this. its VERY VERY bad for the transmission. Its Searching the Gears. NOT GOOD. I cant Stress how bad it is for the tranny. Get it to a tranny shop. I dont know if it is External on the 2g Eclipse or internal. My 89 galant was internal. it cost me like 190 or something to get it fixed. Keep us updated, I wana see how Sharp my Tech skills are.
