Before you begin:
* Consult a repair manual: This is crucial. A factory service manual specific to your vehicle's year, make, and model will show you exactly where the coolant lines connect, the type of connectors used (clamps, quick-connects), and the proper torque specifications for any fasteners. This will prevent damage and leaks.
* Identify your transmission: Look for a casting number on the transmission case. This will help you find the correct information in a repair manual.
* Have the right tools: You'll likely need coolant line wrenches (potentially special ones depending on the connectors), new clamps or o-rings (if necessary), and a clean workspace.
General steps (but ALWAYS verify with your repair manual):
1. Drain the transmission cooler: Before disconnecting anything, drain the transmission cooler to minimize coolant spillage.
2. Locate the coolant lines: These typically connect to the transmission near the pan. They are usually identifiable by their size (relatively small diameter) and location relative to the transmission.
3. Disconnect the lines: Carefully disconnect the lines. Take note of which line goes where. Some connections are quick-connects, while others might be clamped. If using clamps, you may need to loosen or remove them.
4. Clean the connection points: Thoroughly clean the connection points on both the transmission and the lines to ensure a good seal. Use a clean rag and perhaps a suitable solvent (check your repair manual for recommendations).
5. Reconnect the lines: Reconnect the lines, ensuring a secure fit. If using clamps, tighten them to the correct torque specification (as indicated in your repair manual). If using quick-connects, make sure they click securely into place.
6. Re-fill the transmission cooler: Once everything is connected, refill the transmission cooler with the correct type and amount of transmission fluid.
7. Check for leaks: Carefully inspect all connections for leaks.
Important Considerations:
* Coolant type: Use the correct type of coolant specified for your vehicle. Mixing different coolants can cause problems.
* Transmission fluid type: Use the correct type and amount of transmission fluid.
* Torque specifications: Always tighten fasteners to the manufacturer's specified torque. Over-tightening can damage the transmission or lines.
* Safety: Work in a well-ventilated area, and wear safety glasses. Transmission fluid and coolant can be harmful if ingested or come into contact with skin.
In short: There is no "one-size-fits-all" answer to this question. Using a repair manual specific to your vehicle is absolutely essential to correctly connect the coolant lines to your 350 Turbo transmission and avoid potentially serious damage. If you are uncomfortable working on your transmission, take it to a qualified mechanic.
