Transmission Troubles: When to Rebuild or Replace Your Truck's Gears

Replacing vs. Rebuilding: Know When to Switch Gears

When your truck's transmission starts acting up, you're faced with a big decision: rebuild or replace? It's a question we get a lot here at TTS, and the answer, like most things in life, is it depends.

General Rule of Thumb:

  • Rebuild: For lower mileage trucks (under 100,000 miles) with minor issues like slipping gears or occasional hard shifts, rebuilding can be the most cost-effective option.

  • Replace: If your truck has high mileage (over 150,000 miles) or major problems like complete gear failure or loud noises, replacing with a TTS rebuilt unit might be the better call for long-term reliability.

Factors to Consider:

  • Cost: Rebuilding often costs less than replacing, but the final price depends on the extent of the damage and labor costs. We offer free inspections and quotes, so get in touch with us to get a clearer picture of what's best for your situation.

  • Age & Mileage: Older, high-mileage trucks might benefit from a complete replacement, while newer ones experiencing minor issues might be candidates for a rebuild.

  • Severity: Minor issues like a slipping gear can often be fixed with a rebuild, but major damage often means replacement is the more sensible option.

TTS Expertise:

At TTS, we specialize in US Domestic Trucks (Ford, Dodge, GMC, and Chevy) and offer rebuilt units with a 12-month nationwide warranty and one-day turnaround for many models.

Shifting Secrets: Diagnosing & Fixing Solenoid Issues

Solenoids are the unsung heroes of your truck's transmission, controlling the flow of transmission fluid and ensuring smooth shifting. When they fail, it can feel like your truck has developed a mind of its own. Here's how to spot and fix solenoid issues:

Symptoms:

  • Slipping/Erratic Shifting: Gears change unexpectedly during acceleration or deceleration.

  • Hard Shifting: You experience harsh, jarring shifts, often noticeable when stopping or shifting into reverse.

  • No Shifting: The transmission doesn't shift at all, leaving you stranded.

  • Check Engine Light: The check engine light might be on, offering clues about the specific solenoid issue.

Diagnosis:

  1. Trouble Codes: Use an OBD-II scanner to read the trouble codes stored in your truck's computer. These codes can pinpoint the problematic solenoid.

  2. Wiring Check: Carefully inspect the solenoid's wiring and connectors for any damage or corrosion. Repair or replace damaged wiring as needed.

Repair:

  1. Solenoid Replacement: If the wiring checks out, replace the faulty solenoid. It's a straightforward DIY fix with the right tools (and a little mechanical inclination!).

  2. Testing: After replacing the solenoid, take your truck for a drive and see if the previous symptoms are gone. If so, you're good to go!

Extra Tips:

  • Get Help: If you're unsure about DIY repairs, it's always best to consult a qualified mechanic.

  • Right Fluid: Always use the correct transmission fluid specified in your owner's manual. Using the wrong fluid can lead to all sorts of transmission problems.

  • Multi-Solenoid Fix: If multiple solenoids have failed, it's a good idea to consider replacing all of them together. This can save you time and headaches down the road.
