Hello everyone, I’ve been a lurker here for a long time but finally wanted to ask specific questions.
I’ve got a 2013 ram 3500 mega cab Laramie limited with just shy of 200,000 miles on it.
I’ve maintained the trans per the recommended service intervals and had to replace the solenoid pack around 9 months ago.
Last week while driving along at 45 or so mph the truck just seemed to shift into first gear. I pulled over, shut it off and restarted and it tried to shift into second okay but then dropped back to first. I was a half mile from my cousin’s house and limped it there thinking I’d reached the end of the road for the trans.
Pulled codes and they were all shift codes related to ratios being off so I did a bunch of browsing forums etc and found a couple ideas. Check the input and output speed sensors finding the input was not showing proper resistance so I swapped it thinking I’d found the issue.
It tried to shift better but still dropped to 1st quickly.
Yesterday I pulled the pan to look for anything mechanical, found a torx head sheared off, the washer and a small piece of metal.
Looking at the interior I could see the plate that holds the accumulator valves in place had broken a head off a bolt as well as the corner of the plate away from the bolt remaining.
Pulled the valve body and at first thought I was missing another torx screw so I spent an hour scouring everything I could imagine looking for it.
Zero metal shavings, very slight sludge on the magnet etc. and when I looked closely at the plate it doesn’t show the same wear as the other screw holes and the threads in the valve body look as though they never had a screw installed so I’m confident the screw was left out from the original build. The OD &UD pistons were popped out with the OD piston seal torn.

I really don’t have the funds to replace the trans at this time and would prefer not to just replace the entire valve body though if that’s what it takes I can. I’m hoping I can simply get the OD &UD accumulator pistons and a new plate to patch it up for another few thousand miles while I save up for a new trans or possibly trade the truck for a 2020 with a warranty etc.
Got divorced earlier in ‘19 and that drained my reserves or I’d just have it replaced and keep on going another few years. I’m typically not a guy to take shortcuts but would like a band aid fix for now.
