I have an 89 560 sel w/ 105,000 miles, I put the last 5,000 on it and everything has been fine untill yesterday. I did 1,400 miles in 24 hours (palm beach to NY) and the following day it did about 30 miles fine then I put it into reverse and nothing, put it back into drive and nothing. Checked the fluid level, no problems, engine is running fine, etc.. Just the transmission is compleatly non responsive out of the blue. Please help, stuck at inlaws on turkeyday.
