| Description of the problem | No shifting issues for the first 49,000 miles. Now, at 50k miles, the vehicle shifts hard in all gears, but mostly in 6th, 7th, and 8th. The hard shift sometimes feels like a 5 lbs hammer slamming into the metal frame of the vehicle. Not all shifts are hard. Most hard shifts are when holding the throttle steady and the vehicle slowly approaches a shift point. In 8th gear you can hold 5% throttle to maintain highway speed, then give 10% more throttle for an uphill and the transmission will stay in 8th gear, but briefly shutter followed by an obvious bang or jerk of the vehicle. Some bad shifts are repetitive with four or five hesitations and pops or bangs of the transmission. These hard clunks happen at 30-45 mph, or at highway speeds of 75-80 mph. Some feel like bumps in the road, while others feel like violent bangs. The issue does not happen when giving the vehicle 80% or more throttle. Issues are usually at 5% to 35% throttle. It happens most often when accelerating towards a normal shift point slowly. Before the normal shift, the transmission will slip and bang. On a twenty-minute drive of mixed highway and city, it may bang 5 to 10 times or more. Violent bangs are once or twice per week, but sometimes twice a day. The driving situation is what increases the likelihood of feeling a bad kick or bang. Not all bangs result in a shift. Some bangs happen but the vehicle stays in the same gear as if it just slipped and then caught the same gear again. |
