6 speed shifting from 1st to 2nd gear on 1995 Chevrolet Corvette

About 1 in 4 times when making a left turn I find that it is difficult to shift from 1st to 2nd gear (grinding). Mileage is 30k. Any suggestions?

Read your owners manual or look on your guage cluster, you probably will see a light flash saying "One to Four" the trans is set up that way to get better fuel mileage
