Torque converter shudder and warranty?

[Wild one]

My manual says nothing about fluid change on the 8-speed, it does on the 6-speed tho. Mine is a 2014 Ran 1500 with a lifetime warranty. I checked with my service manager to be sure and he agreed, nothing was mentioned in the manual about changing the fluid.

First paragraph might interest you,reconmended service interval is 100,000 kms (62,500 miles) or 8 years which ever comes first

These are the factory instructions for checking the level on the trucks,the first paragraph is important,as you have to jack the truck up in the air a fair bit to level the pan rail.These are the instructions that come with a "brand new" 8 speed when bought from the dealer.

My 16 clearly states lifetime fill.

Mopar Maxcare service contract thinks it is a lifetime fill also as there is now service interval in the owner's manual for the 8 speed.
However, they aren't going to change a converter without a code either.
SO, where does that leave you? Depends on if you are going to keep the truck for several more years or not.
If you are, you have 2 choices.
A. change the fluid and/or filter now.
B. leave it alone and hope it either fails or does no more damage between now and the service agreement expiration date - and change the fluid after that point if failure doesn't occur.

What makes you think it's the T/C? It could be a few things.

You really need to have it professionally looked at. Have the best tranny guy at the dealer look at it. Find out in advance who the tranny guy at the dealership is ..and make sure they're going to be working on your truck the day you take it in. You don't want their mediocre guy working on it ..get thier most advanced tech. And if they don't come up with anything, take it to a tranny shop. See if their opinions match. There is a whole troubleshooting procedure in the service manual. That includes taking pressures too. It could well be something simple and inexpensive. (fingers crossed)
