Hi. I'm glad I found this site. Hope you guys/girls can help me out. I have a 1985 Mercedes-Benz 500 SEL that I am fixing up because I bought it for a steal! However, after replacing the radiator, thermostat and fixing power windows, now the car won't shift into second gear. It is an automatic trans and I can go about 25 mph but it won't shift to let me go faster. I checked the transmission fluid but I don't think it has been changed in awhile. Any suggestions? Any help is very much appreciated!
