Intermittent electrical issues - windows, headlights, high beams, dash lights

Thank you for your input. Could these problems have been the result of the transmission work? Do you know what I should expect this to cost to repair? Will the shop be able to diagnose and repair if the problem isn't happening at the moment or do I need to wait until it's happening to bring it in? Many thanks!

return to repair shop and ask them to ck bee housing should be no charge

Thanks so much. Will the mechanic be able to find the problem even if the electrical is having a good day or should I wait for a bad day so he can tell if he's fixed it? Appreciate the feedback!

Hi. Thanks for your input. I just had the car repaired. it turned out that it had nothing to do with the transmission. It was a coincidence that it had a problem a few weeks after the transmission work. It ended up not being the bell housing or ground wires, but rather the front electric module (FEM). To make it all the more dramatic, Ford is not making that part right now. They lost the company that was manufacturing for them and are in the process of finding another company to manufacture again. This is leaving approx 15 people on a waiting list for the part that controls all the front end electronics including the headlights! I searched high and low and finally found a 2004 T-bird at a salvage yard about an hour away and was able to harvest the part. Of course the risk is that the part is as old as my car so it may not last forever but for a $150 part, my car is back on the road and operating perfectly. Hopefully the part will hold out until Ford has a new FEM manufacturer. New the part costs $650. At that price, fingers crossed that the used one holds out for the life of the car. It does seem more than odd that within a month of my extended warranty expiring all these problems have ensued. I'm trying to stuff down conspiracy theory thoughts. Aside from the coils in year 5 under the extended warranty, I haven't had major problems until now in year 9. I'm kicking myself for not purchasing another extension on the warranty. Out of warranty, Ford wanted $4500 to do the transmission so I took it to an independent for less than half. So no chance of any love from Ford. I'm not sure if it would actually qualify as a lemon, but having to make all these repairs at 49k miles definitely leaves a sour taste in my mouth... pun intended.
