The 2007 GM 4L60E automatic transmission uses Dexron VI automatic transmission fluid (ATF).
GM’s guidance for this era specifies Dexron VI as the preferred ATF. Dexron VI is backwards compatible with earlier Dexron formulations, and if Dexron VI isn’t available, Dexron III can be used as a temporary substitute. Avoid non-ATF fluids such as Type F and fluids not approved for automatic transmissions.
Fluid specification and compatibility
The following overview explains which fluids are acceptable for the 2007 4L60E and how they relate to GM’s specifications.
Before you review the list, note that the 4L60E is designed to run best with the newer Dexron VI fluid, with Dexron III standing in only as a short-term fallback if Dexron VI cannot be sourced promptly.
- Dexron VI ATF — the recommended and preferred fluid for the 2007 4L60E.
- Dexron III ATF — acceptable as a temporary substitute if Dexron VI is not available; plan to replace with Dexron VI as soon as possible.
- Other fluids to avoid — Type F, Mercon V, or fluids not explicitly approved for GM automatic transmissions.
In short, Dexron VI is the best choice for ongoing maintenance, with Dexron III usable only as a short-term fallback.
Practical guidance for servicing
For a typical fluid change or service on a 2007 4L60E, follow these steps to ensure proper fluid level and performance.
- Warm up the vehicle to operating temperature to ensure accurate level readings.
- With the vehicle on a level surface, safely lift and support the car, then drain the transmission pan and remove the old fluid.
- Replace the transmission filter and, if applicable, the pan gasket.
- Fill with Dexron VI ATF to the factory-specified level, typically starting with about 9–12 quarts depending on your exact configuration and whether a full drain was performed.
- Start the engine, move through each gear (Park, Reverse, Neutral, Drive) with the foot on the brake, and then recheck the level with the engine running and the transmission warm. Add fluid as needed to reach the correct level.
After you complete the service, recheck for leaks and test-drive the vehicle to confirm smooth shifting and proper operation.
Summary
For a 2007 4L60E, Dexron VI ATF is the recommended fluid. Dexron III can be used only as a temporary substitute if Dexron VI isn’t available, with the expectation of switching to Dexron VI soon. Avoid Type F and other non-ATF fluids. When servicing, follow proper steps to drain, replace the filter, refill with the correct ATF, and verify the fluid level with the engine warm. This approach helps maintain shifting quality and transmission longevity.
