Mobius, what benefits are expected with the fluid switch?
All of the benefits typically associated with synthetic oil - reduced friction and associated wear, greater oil longevity and increased oil change intervals.Mobius, what benefits are expected with the fluid switch?
I've already done research on the most popular full-synthetic oils suitable for the 7 speed transmission, and there are a number of DEXRON III ATF-spec'd oils that will be direct replacements, but I'm curious to hear experienced perspectives and opinions from those who have already used these alternatives.Curious about this myself. What products out there currently meet the factory specs such that warrantly cannot be questioned by dealer?
See, this is why I wanted to ask the forum. I still plan to change the fluid, but I'll rethink if I want to go full synthetic or not.Just noticed this on the Tremec site:
Q: Why not use a synthetic fluid?
A: Some brands of synthetic fluid contain powerful detergents and additives that can prove harmful to your transmission's synchronizers. While many synthetic fluids perform very well, in most cases, we do not recommend their use. Furthermore, they may void your warranty. For peace of mind, remember that TREMEC conducts all of its OEM validation testing using conventional fluids without issue.
Yes, I'm sure that's true in many cases.I'm not saying it's A waste of money.I have heard of manual transmissions going over 100,000 miles without changing the gear oil.
Mobius, I will follow your research into whether our C7's will benefit from synthetic transmission oil...Yes, I'm sure that's true in many cases.
I change out manual transmission fluid at 25,000 mile intervals and I've never had a transmission wear out. Example - I'm the original owner of a 5-speed 2005 Civic that has over 473,000 miles (Amsoil Synthetic Synchromesh Transmission fluid every 25k) and still gets 45 MPG highway (synthetic motor oil since 500 miles, changed at 5k intervals).
That's the power of synthetic oil.
I also routinely red line my C7 engine, and I think the transmission deserves some fresh oil for all of her good service, and her ability to tolerate my demands.
Not one of my finer moments selling my 2004 5-speed Honda Civic with 78K in 2011 so I could buy a 2011 Camaro SS. 473K!! Wow!!I'm the original owner of a 5-speed 2005 Civic that has over 473,000 miles (Amsoil Synthetic Synchromesh Transmission fluid every 25k) and still gets 45 MPG highway (synthetic motor oil since 500 miles, changed at 5k intervals).
Here are the diff drain and fill plugs.Can a kind soul either provide a pic or point me to a drawing of the location for the drain and fill plugs on the manual tranny for the C7?
I would like to do this also.
