Lubegard 19540 Seal-E-Zee Cone Set: The Ultimate Solution for GM 5L40E Transmission Seals Review

This Automotive transmission seal conditioner worked wonders for me. As my tests showed, it stopped oil leaks in my car's transmission within a week of application. It's a great tool for those who want to save time and money on transmission repairs. It's easy to use and seems to offer long-lasting performance. The only downside is that it's a bit pricey. Overall, I'm very pleased with the results, and I'd certainly recommend this product to my fellow automotive enthusiasts.

If you buy these then be careful and I wish you the best of luck with your project! If you think you need two freezer cans buy four, I ended up pulling out my 30# can of refrigerant to get the job done. It's a crappy shot, but compared to 1000 for a factory tool.

The cones worked great! The spray to use with them is hard to find and inconvenient to use. But I'm not rating the spray, just the cones. Use the cones as directed, but instead of spraying, simply assemble the plunger and cones, then place in the freezer for fifteen minutes or more. Would have given five stars if the product hadn't advised using the spray.
