Well, im kinda in the same boat. Im on a spec 2+ and lwfw though. Im getting intermittent slippage under max boost. Still rips the tires loose, but on some highway pulls it slips.Today after a long day driving in heat and traffic, with AC. I experienced clutch slippage that seemed fairly severe. It was not solidly engaging, but prior to this zero signs of slippage, just all the suddent not good. . No smell,
This a normal way to see it go?
Could the heat have caused an issue that may resolve in cooler temp?
Your clutch is having issues. Premature clutch failure could be fluid contamination, or excessive wear/faulty parts.
First step is checking the bellhousing weephole. If you see fluid there, either brake or oil, then you know its either the slave or rear main seal.
If its dry, then your mods/driving habits will be in question. Just SOP.
If you are relativly stock, no track or drag, i hope ford replaces the faulty parts. If not, then i suggest not looking at spec clutches, lol.
