Have a BD Mastiff "07" and need some input on a issue I have been experiencing. When attempting to shift into 2nd it goes into Neutral, wont let me upshift any further, and I have to down shift to 1st then back to 2nd. This doesnt occur everytime attempting to shift to 2nd, but is pretty frequent. I thought maybe clutch or linkage adjustment but wanted some opinions before tweeking anything. Any insight would be appreciated!
