Hi everbody! I just purchased a 85 with the 4+3 manual however I dont believe its working right. At 75 mph my RPM's are 3000. Here is what I do know. I have a console switch for the overdrive which seems to be working, when switch is on I can start out in first and light on dash is out, second through fourth light on dash is on... However from what I have read RPM's are way to high.. It dosn't seem to be working... No upshifting at all.. Rpm's remain the same whether switch is on or off through the gears... Clutch seems to be okay but once in a while I grind going into first(possibly my fault because of really no neutral feeling for gearshift). I had the car up on a lift and the whole underneath of my car really looks brand NEW! No leaks around the overdrive unit at all. Heres the kicker say im in second,third or fourth with overdrive on, if I let off the gas pedal slow down a little bit,then turn the overdrive off it actually seems to downshift.. Its like droping a gear... This really doesnt Make since to me? My car has 101000 miles on it and really is in good shape. Does any body know where I might be able to take my car for repair? A honest mechanic Please? Sorry for the long post...
