I'm sure I can help you with your questions about the LE 7500 Monolec Power Fluid. I have worked for LE for over 23 years and am a Certified Lubrication Specialist buy the STLE. If you wish to email me I would be glad to answer your specific questions. Yes the LE 7500 will reduce temps in your trans. Your truck has the Mag-Hytec pan on it as well and they say that you should see a temperature drop by using that as well. They also say that by using the LE7500 and the Mag-Hytec pan that you will see even more temp drop by using both of them than by just using just one of them.
Sincerely,
Kevin Dinwiddie
