Bringing a long-dormant vehicle back to life can be a rewarding experience‚ but it also presents unique challenges. One critical component that often requires attention after years of disuse is the transmission. Here’s a comprehensive guide to cleaning and servicing the transmission to ensure smooth operation⁚
Assessing the Situation
Before diving into any work‚ it’s essential to understand the vehicle’s history and the extent of its dormancy. Factors to consider include⁚
- Storage Conditions⁚ Was the vehicle stored indoors or outdoors? Was it covered or exposed to the elements?
