I haven’t seen that guide! What did they say about the torque converter? It’s sometimes overlooked but crucial for performance.

The torque converter is vital! It transfers power from the engine to the transmission. Understanding how to identify it can save you headaches later on. Plus, knowing the clutch packs can aid in troubleshooting problems too.

I’m curious, what common issues do people face with the 4L60E? I’ve been researching clutch pack failures. Anyone have tips on identification?

Clutch packs can indeed be tricky. If you notice slipping or erratic shifting, they might be the issue. A visual check is also beneficial.

Great advice, iberger! I’ve had my fair share of issues with valve bodies too. Sometimes, just cleaning or adjusting them can make a massive difference!

The maintenance tutorial I’m working on includes cleanup tips for the valve body! Almost everyone overlooks this, but it’s key to the longevity of the transmission.

That sounds awesome, tsaunders! A lot of people could really benefit from a detailed breakdown of each part. I believe troubleshooting starts with the valve body.
