Honestly..it'* tougher for my tired eyes to read. Then since I don't text a lot..the sum1 stuff needs to be translated by my aging brain.
In my quick scan, diagnose and run for the next post world..it was tougher and while we help many folks, some days we ask for some help from you guys to make things easier on us.
I definately appreciate the attempt and can understand that it'* much tougher to type from a phone.
On the O2 sensors. If you don't have a check engine light there is no need to replace the rear sensor. The way to check the rear sensor is via a code, no code for a rear sensor issue..then there is no rear sensor issue to address. The front O2 can get slow, meaning if you are used to seeing O2'* on a scan tool and watch the toggling, it'll be slow and mpg'* are usually down. That is a classic sign of a bad front O2. A code for a front O2 would be the other way to know it'* bad.
For the torque converter..does your car drive funny? A torque converter isn't an electrical item, but the soleniod that can control it would be. I'd want to see you get the codes checked by somewhere like Autozone to review a TC code. If you can, please have them pull the codes, then bring the code numbers back to the forum and we can help diagnose from there.
Transmission bolt.. did they show you the missing bolt or can you see one missing from around the transmission bellhousing under the exhaust cross over? There should be 4, and a hole for a locating pin that looks like a 5th hole. There'* also a 5th bolt, but it'* on the passenger side and you can't see it w/o taking other parts off, which they didn't do.
