Pcm Help
So my 99 dodge durango would get to operating temp and my old pcm would get hot and throw a no bus code. So I ordered a new pcm got it today and transmission was having trouble accelerating off the line almost like it was in limp mode. The SUV will drive up to 40mph and stay with no issue and is at 2000rpm. The problem is it slow to get up there. So I ran a obd2 test and got P0743, P0443, and P0753. All of these codes was not on with the old pcm and showed up right away with new pcm. Needing any info I can get before I put more money into this. Also is it possible that they programmed it wrong? When I bought it they asked for my VIN only. I ready that they would also need my milage but they never asked for it so I never gave it. I don't want to buy the parts for these codes just for the problem to continue if its the new pcm.

before the pcm overheats and throws no bus code I have a P0132 code. when the pcm overheats it loses communication and throws no bus code. I'm kind of not understanding you are you saying my new pcm is fine and those codes are correct? because I don't get those codes with the old pcm and car runs and drives fine until the pcm overheats.

yeah its all so odd to me thats why I am seeking information heres the info from pcms
Original PCM:
P0132
New PCM:
P0753
P0743
P0443
Now with my experience which isn't much some codes don't come back right away once battery has been disconnect for awhile and my battery was connected for a like 5 hours while I struggled to removal the factory ball joints to install new ones. Now I don't remember if it can happen with 02 sensor code but if possible the 02 sensor code just isn't registered in the new pcm yet?
And yeah just wanted to confirm I didn't have much options. I have lifetime warranty for new pcm but after talking to flagship it sounds like they might try to make me jump through hoops just to get a working one.
