I have never used anti sieze on a pan bolt. I don't think you will find anyone that has put more pans on than I have in 45 years of doing this shit. Name your so called builder.
For anyone else with this type of problem, an impact driver is a great tool for loosening stuck bolts or screws.
Correct plus if you have an allen head bolt that is loose on your socket; use a torx bit instead. They fit tighter.
He is a local guy here, I don't think it was the trans builder's fault, I believe that the issue lies with a certain shop that did subsequent work on the truck. The same one that couldn't figure out how to unplug the turbine speed sensor, so they just busted it...then zip-tied it back together and didn't say anything hoping no one would notice. :spit:
The same shop who's "professional" tuner has sent who knows how many trucks to the shop with busted engines, one I know of personally 3 times. All while telling the owners that their truck will hold over 500 HP forever...:rofl:
Glad u got them out, dude, come over an help me get my baby running..
