I have a 91 na manual transmission. I can downshift from 5th to4th easily, from 4th to 3rd easily; but going to 3rd to 2nd causes serious grinding until I slow down to 5 or 10 mph. Same with going to 2nd to 1st. When I bought the car in July 05 the seller said the engine was recently replaced with a Camry 2.2 with 5k miles on it.What is causing this and can anyone give me a ballpark $ amount for the repair. I live in the Cleveland OH area. Thanks for any info.
