Make sure the old filters rubber seal didnt stick to the filter housing when you removed it. While you have the filter off clean up the housing to filter seal. Ut some engine oil on the filter rubber seal befre putting it back on. Costs nothing and just takes a half hour of your time.
Engine cutting out at high
I need model year and engine size?
How long since a tune-up? Any applicable trouble codes?
I can only help with testing, what testing have you done? Did you use a gage and check proper fuel pressure? Some of the national brand auto stores will check codes for free, if there are any? Do you have drive by wire throttle? Does the speedometer work ok? Sometimes the vss can effect shift points? I'm not telling you to replace anything, but, do some testing. I can't go by what the mechanic did or didn't do. I can't go by what they said.

You might look for a loose or corroded ground. Any problems with the horn or wiper wash motor? I assumed a 5.0L engine. Info I see says there is a ground splice point and a couple of common grounds. If those systems are affected, it would be even more likely. Check fuses as well.
Why is Allison transmission banging hard into gear?
Probably a bad solenoid inside the pan if you bring it to a shop and have them scan the tcm the computer should tell you the problem unfortunately the service engine light won't turn on with a tranny trouble code unless it is a major failure that puts a bind on the motor
Reset dash lights
I got some subs hookes up in my 2012 dodge avenger and now all my dash lights are on and my lock key will not let me unlock or lock doors what is wrong
Need 12v switched power source in the dash.
best thing to do, as i presume you want a completely new power feed , run a power and earth cable to the battery and connect the power to the positive pole and place a fuse inline at that point and connect the earth wire to the neg pole , leave the fuse out until you have run the cable to where you want it ,this is a much safer way as can't interfere with any other components already fitted keep me updated if you wish
