I have a 95 GTP with the DOHC motor. The problem first happened about 2 months ago, the car wouldn´t go into high gear and on the parkway it was about 3100 RPMS at 70. But it started to work again and I forgot about it. Until it happened this morning on the way home from work. The trans was working fine and then I noticed the rpms were 3100. I tried shifting into the lower gear and then shifting up again but that didn´t help. The trans shifts fine but just won´t go into high gear. Checked the trans fluid and the level was fine. Trans shifts nice into the other gears. The car has 70,000 miles on it and the trans was rebuilt just before I bought it. Any ideas. Could it be the linkage is out of adjustment. Sometimes I have a problem with that.
