I got a new convertor and installed it in my 98 1500 4x4. After refilling the tranny with new ATF +4 and a new filter I was still getting some shudder. I was not happy. I drove the truck around for a week and then the shudder stopped. It has been 3 weeks since it last shuddered. I have to believe that there was a piece of trash lodged in the lock-up solinoid valve and it has now moved on. The tranny is working as it should. I just hope this piece of trash doesn't get stuck somewhere else.

Hopefully it has been caught in the filter and you plan on checking that in 24K - 30K miles.

 

Sounds like a good reason to drain the fluid and change the filter again.

 

I would say your right Cereal Killer.
