1990-2007 Duramax NV4500 Manual Transmission 3rd & 4th Gear Fork (ZMNV18302)

To put it plainly, your gear forks engage and disengage the gears themselves and move them into the correct position, allowing you to select different ratios for varying speeds and applications. If you have difficulty changing gears, slippage, grinding, or strange noises/ smells, this could be a sign that your gear fork has failed. It is best to get your transmission inspected as soon as possible, as a failing fork can potentially cause detrimental damage to your transmission.
