Synthetic High Temperature Automatic Transmission Fluid provides the gear protection of a GL4 gear oil in an Automatic Transmission Fluid and provides a higher viscosity at higher operating temperatures, allowing the transmission to operate at 70 Degree Fahrenheit higher temperature and still provide the optimal shiftability and improved torque converter efficiency. The evaporation characteristics are significantly improved, being twice as good as our Synthetic Automatic Transmission Fluid and five times better than a petroleum Automatic Transmission Fluid. The improved thermal stability significantly reduces the rapid evaporation of the Automatic Transmission Fluid which can produce a frothing out the filler tube. The balanced frictional characteristics provides smooth and consistent shifts for extended drain intervals. The superior stability compared to petroleum Automatic Transmission Fluids allows high temperature operation without varnishing valves and clutches which leads to transmission failure. High Temperature Automatic Transmission Fluid is perfect for heavily loaded vehicles which see high temperatures and automatic transaxles which are benefitted by the extreme pressure protection of a GL4 gear oil to lubricate the final drive. This product can be used in manual transmissions which require Automatic Transmission Fluids and will provide much better gear protection than a petroleum Automatic Transmission Fluid; however, MTL® will provide better wear protection and better low temperature shiftability in most manual transmissions which call for an Automatic Transmission Fluid. High Temperature Automatic Transmission Fluid is suitable for use in automatic and manual transmissions and transaxles where Dexron® III, Dexron® II or Mercon® is recommended.

These tire repair reamers work great for plug/other type repairs
Size: 3 mm 4.5 mm 6 mm Tire, Number of Items: 3
These tire repair reamers work great for plug/other type repairs. Gone are the days of manually fighting a hand reamer through rough rubber. This is an efficient, neat and clean way to prepare a tire for the repair. Will purchase again as needed.

Got what I paid for.
Size: 3 mm 4.5 mm 6 mm Tire, Number of Items: 3
I dropped my drill with the bit installed. It broke quite easily. It was a relatively inexpensive so I can't complain. A higher quality harder metal would have earned 5 stars.

Great product
Size: 3 mm 4.5 mm 6 mm Tire, Number of Items: 3
These bits are great. We use them every day e when patching or plugging tires. Having multiple sizes helps us match the bit to the patch we use.

Easy on the hands
Size: 3 mm 4.5 mm 6 mm Tire, Number of Items: 3
These make it much easier to ream tires that have been punctured. It takes the stress off of your hands, forearms and elbows especially when you’re plugging higher ply tires.

Handy Tool for Frequent Flat Tire Repairs
Size: 3 mm 4.5 mm 6 mm Tire, Number of Items: 3
Good quality and easy to use. As someone involved in emergency services, we deal with flat tires often, and this tool has been really helpful. The bits are sharp, durable, and make the repair process quicker and cleaner. Great to keep on hand for regular use or in a roadside kit.
