I recently changed my trans fluid and filter, replaced the filter seal and both filters. About 500 miles later, it is now intermittantly shuddering and stalling while slowing from about 10mph to zero. Some times the computer catches it, and other times is just stalls. Once I restart it works fine. the code it has is po841 lr pressure switch rationality. The fluid is up to the hot full when the vehicle is idling in neutral hot. there is a bunch of air bubbles on the dipstick, not sure if this is normal or not. Any help would be greatly appreciated I want to fix this soon.

Well reading other threads like this one before, I would think one of those filters is not put in correct and it is sucking in air. You might have to drop the pan and check to make sure those filters are put in correctly. That would be my guess. Hope it helps.

My response:
Some bubbles are normal. If the problem is intermittent, I would clear your codes with a handheld or a tuner and reset your adaptive values by pulling the correct fuse or unhooking your battery and touching pos-neg cable together for 20sec.

Guys have had problems with incorrect installations(not seated correctly or left old seal in)
There is also issues about drainback with revised returnline filters but that's not the cause of your problem.
Try resetting your adeaptive values by doing the above and then your next step would be checking your filters for correct installation of a new pressure sensor switch.

 

I started with unhooking my battery and letting it sit for a half hour, and then hooking it back up. Cel is off, no more slipping, still stutters occasionally while braking, barely noticable. I will drive it for a couple of days to see what happens, I hate taking the pan down so I will avoid that until absolutely nessecary.
