Texasota Report post Posted June 26, 2017 (edited) Don't confuse the transmission coolant with the transmission lubricant. There's the motor/electronics coolant ( MEC ) system and there's the transmission lubricant cooling system. In the plug-ins, there's an electric pump for the lubricant cooling system in addition to the ICE driven one. The hybrids don't have that and when they upped the max EV speed of the hybrids from 60 to 86 with software updates, it was surmised that there was lubricant overheat that contributed to the rash of failures. Nobody but Ford knows for sure. If there was a bearing manufacturing problem from a vendor, the vehicles affected should be known and may be in the thousands. We are continuing to see on this forum too many failures of these first Ford built transmissions as they age. Since they don't fail catastrophically and cause a safety issue no recall has been issued and Ford is just waiting out the 8/100,000 hybrid warranty. Sad ! !I was a big advocate for these Ford hybrids since I got mine in July 09 but Ford's response to these 2013 transmission failures is ( put in your own word ).It could be the case that Ford does not know which transmissions are going to fail even though they know what the reason is for the ones that do fail. Only a small percentage of 2013's have failed and even fewer 2014s. A recall to replace all transmissions that "might" fail seems over the top to me. Evidence on this forum strongly suggests that Ford has honored the transmission warranty when owner's have experienced a failure. PT's transmission was replaced under warranty and it was just under the 100,000 mile threshold if I remember correctly. I disagree with your accusation that Ford is waiting out the 8/100,000 warranty. You are basing that on speculation not facts.

Texasota Report post Posted June 26, 2017 My 2010 manual doesn't mention it. I found the 2010 FFH manual online and it does mention it: TRANSMISSION FLUIDChecking electronically-controlled Continuously Variable Transmission (eCVT) The eCVT does not have an underhood transmission fluid dipstick. Refer to your scheduled maintenance information for scheduled intervals for fluid checks and changes. Your transmission does not consume fluid. It is designed to be filled for life. However, the fluid level should be checked if the transmission is not working properly, or if you notice some sign of fluid leakage. The above references the "scheduled maintenance information" which is a separate manual (also available online) and it states: 150,000 miles Change automatic transmission fluid and filter (filter not required on 6F35). (Except vehicles equipped with the TorqShift transmission). It appears that the requirement is the same (150,000 miles) as the 2013+ FFHs. However, the wording "designed to be filled for life" does introduce some ambiguity. 1 ptjones reacted to this Quote Share this post Link to post Share on other sites
