I have had my 89 Sedan for 3 years now after it was given to me. I have put over 50,000 miles on it and have had to replace the transmission, brakes, shocks and struts, alternator, battery, and windshield. The transmission was bought from a guy in Houston who imports used parts from Japan. Having lived in Japan for three years, I know they don't put many miles on cars and don't keep em very long like we do here. Anyway, after my friend installed the transmission for me over a year ago, I noticed right away it would stick in first gear and rev the engine up pretty high before shifting. I almost couldn't pass inspection. It is not as bad anymore but it still revs up higher than I would like. Anyone have any suggestions on what the problem could be?
