Hi

My name is Ricardo, i recently acquired a 1987 Dodge Raider, 4 cylinders, 2.6 Motor, 5 speed manual transmission. The car is all ok, but i noticed when shifting from 4th speed to 5th the RPM doesn't get lowered. I can tell this from the noise of the motor reving up when i shifth to 5th, its like if 5th gear is just another 4th. Last day i drove another Raider of the same specs of mine, and i noticed the gear shifting, though it was a little change, it was noticeable. I just searched the forum but i got entries on issues on automatic transmissions (overdrives) I'm quite unexperienced on this stuff, and i hope you guys could give me some advice, i like my Raider very much but running at 50 mph with the RPM hitting 3600 its tiring and no-fuel-efficient.

Thank you in advance.
