You proved yourself smart by changing over to the older rod shift transmission linkage on your Cougar SVT. My shift cables are broken again – although this time probably due to the 1st mechanic’s ineptitude and unwillingness to finish the job he started and align it correctly. The end that attaches to the shifter is worn out so the shifter keeps popping off the cable end – which was interesting to reconnect while I was driving in stop and go traffic on the (in)famous Washington Beltway. Unfortunately, the plastic insert on the Contour cables is not replaceable – the only way to fix it is to replace the entire cable set – which is a giant PITA. Oh well.
I also talked to Terry Haines, the transmission guy – if you haven’t heard of him before, he’s a former Ford engineer who has his own shop now, mostly working on MTX75 transmissions. He rebuilt my transmission at 100k, upgraded the shift forks, put in a quaife, replaced two syncros that were going bad. He walked me through the procedure to replace the shift cables (more than I can handle) and we also discussed why the Duratec V6s are puking rods – he unequivocally believes that it is due to the powdered metal connecting rods Ford started using around ’97 – he said that some spec must have changed because earlier Duratec have no con rod issues. In his teardown of motors, he said all the ones that have thrown rods had nothing to do with oil starvation – it all had to do with the con rods stretching out of spec and causing spun bearings then snapping the con rods. He also said SVT engines are more susceptible, due to higher compression and typically harder lives. And he said that the 3L upgrades everyone is doing has the same con rods and is just as at risk – Ford just ignored the problem in the Duratec.
Since you have plans for your Cougar, thought you would be interested in this line of thinking.
