Right.
When temperatures are lower, transmission fluid thickens, leading to the following problems:
* Increased resistance to flow: Thicker fluid has more resistance to flow, resulting in higher temperatures and slower shifting.
* Restricted circulation: Thick fluid has difficulty circulating through the system, which can lead to insufficient lubrication of the internal components of the automatic transmission.
* Component wear: Increased resistance and insufficient lubrication can accelerate wear of automatic transmission components.
* Decreased performance: All of these problems can lead to overall deterioration in automatic transmission performance, including jerking, slipping and rougher shifting.
