Review: Correct Lubricant for Chevy Cruze 6-speed manual transmission - I've followed various blogs and searched for information about which oil is best for my Cruze M32 transmission (since 2014). This GM lubricant used to cost a lot more, so that's even more reason to use the actual GM lube. After a number of years I noticed several people posting about bearing failures after switching to other lubes. It took time before their problems showed up. I've been turning wrenches for 60 years and I've seen a lot over that span. I recently retired as a mechanic major airline (including a turbine shop inspector and 12 years in the ground support equipment garage). I've seen many lubrication issues over the years. I don't recall which engine it was, but just before I retired we had bulletins warning us to check for the proper engine lubricant, because what he had been using (for years) had just been superceded. The M32 transmissions had/has issues. GM, no doubt, sunk a lot of money into trying to create the best lube, and if for no other reason, to mitigate bearing issues. I've decided to use the actual GM oil, and the reduced pricing makes that decision even easier. ## Features - High-quality manual transmission fluid - Specifically formulated to provide good shifting movements - Manufactured for transmission efficiency in cold weather ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B008BZT8FY | | Best Sellers Rank | #578,228 in Automotive ( See Top 100 in Automotive ) #470 in Transmission Fluids | | Brand | ACDelco | | Brand Name | ACDelco | | Customer Reviews | 4.6 out of 5 stars 47 Reviews | | Global Trade Identification Number | 00707773844588, 40707773844586 | | Included Components | Transmission Fluid | | Item Form | Oil | | Item Type Name | Transmission Fluid | | Liquid Volume | 1 quarts | | Manufacturer | ACDelco | | Material | Oil | | Model Number | 10-4037 | | Number of Items | 1 | | Part Number | 10-4037 | | Recommended Uses For Product | Transmission Fluid | | Specific Uses For Product | Prevent Corrosion , Maintain Efficiency in Cold Weather | | UPC | 707773844588 | | Unit Count | 32 Fluid Ounces | | Viscosity | 70W sae_grade | | Warranty Description | No Warranty | ## Product Details - **Brand:** ACDelco - **Liquid Volume:** 1 Quarts - **Material:** Oil - **Recommended Uses For Product:** Transmission Fluid - **Viscosity:** 70W sae_grade ## Images ![GM Original Equipment 10-4037 70W BOT 303 Modified Low Viscosity Manual Transmission Fluid - 1 qt - Image 1](https://m.media-amazon.com/images/I/61riTNM+SYL.jpg) ## Questions & Answers **Q: Should I flush my engine oil before switching from conventional to synthetic oil or vice versa?** A: No, it is not necessary to flush your engine when switching between motor oils. Typically, conducting a routine oil change and replacing the conventional oil with a synthetic motor oil will not require any additional maintenance. **Q: Do I need a special oil filter for a synthetic oil?** A: No, synthetic motor oil does not require you use a special filter. Oil filters are used based on vehicle specifications. Refer to your vehicle Owner’s Manual for guidance on what type of oil filter to use. **Q: Is there a way to tell if my engine oil needs to be changed or is running low?** A: Yes, if equipped, your vehicle’s oil life monitoring system will inform you when your motor oil needs to be changed. Refer to your vehicle Owner’s Manual for more specific guidelines. **Q: Does my transmission fluid need to be changed as regularly as my oil?** A: No, typically, transmission fluid lasts much longer than most engine oils. Refer to your vehicle Owner’s Manual to identify how often and when your transmission fluid should be changed. Severe usage and regular usage descriptions are provided. **Q: Is there a difference between power steering fluid and transmission fluid?** A: Yes, there is a difference. There are many types of transmission fluid. GM Genuine Parts and ACDelco recommend referring to your vehicle Owner’s Manual for fluid recommendations for all vehicle systems. ## Customer Reviews ### ⭐⭐⭐⭐⭐ great for the reduction gears in my EV *by G***Y on February 2, 2026* I used this in the reduction gear on my 19 Hyundai Ioniq EV at 50k miles.
