Lot SR20210388: 2005 Nissan 350Z Touring

Based on my research, here are the most common problems with the 2005 Nissan 350Z automatic transmission:

1. Jerky/Lurching Shifts (1st to 2nd gear) This is the most reported issue, especially at low speeds. The transmission can shift harshly from 1st to 2nd gear when driving slowly in traffic. This is often caused by the transmission control module programming or worn valve body components.

2. Transmission Cooler Issues The automatic transmission uses a cooler that’s integrated into the radiator, and failures can cause coolant to mix with transmission fluid, leading to transmission failure. This was significant enough that Nissan issued a service campaign.

3. Valve Body Problems The valve body can develop issues causing erratic shifting, delayed engagement, or harsh shifts. This affects multiple gears and typically requires valve body replacement.

4. Torque Converter Issues Some owners report torque converter shudder or failure, particularly in higher mileage vehicles like the one you’re looking at (155k miles).

5. Software/Programming Issues Early 2005 models had transmission control module (TCM) software issues that caused various shifting problems. Nissan released updated software for many of these issues.

Good News: Most of these issues have solutions, and many were addressed under Nissan service campaigns. For a high-mileage car like this one, I’d recommend having the transmission fluid condition checked and ensuring any software updates were performed.

Would you like me to help you find similar 350Zs with lower mileage or manual transmissions, or do you have other questions about this car?
