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.

Great shirt, a bit large in arms
Color: A - Moon Gray, Size: Medium
I really like the cut and texture of the shirt. The only thing I would say is it is loose in the arms unless you’re a body builder. My arms are toned, muscular, but more lean than thick, so if you like a snug sleeve this is probably not for you. I’m 5’9” 180bs for reference and wear a medium.

Check the size chart and reviews!
Color: Black, Size: 3X-Large, Color: Black, Size: 3X-Large
Bought this for my husband and if i didnt check the reviews I would ordered it too small. He normally wears a XL in T-shirts but he has very large arms so the 3XL in this fits him comfortably. The material is a bit stretchy so he could have probably taken the 2XL but I am satisfied with how the 3XL looks on him. He looks so good!

Size discrepancy
Color: Wine Red, Size: Small
I like the look and feel of this shirt, but I originally bought a medium and it was too big, so I bought a small. Both shirts are the exact same size. It is labeled on the collar as a different size, but it's the same. If anything the small is slightly larger

Happy with my purchase
Color: Black, Size: X-Large
The material is good quality and it did great in the gentle cycle of my washing machine. I hung it to dry, no dryer. Looks great.
