That would be about right. A miniature roll of TP.

well I changed my filter and it seemed to help. Its weird my tranny silps going in to fourth gear some times not all the time. It really only did a slight slip after I changed the filter. And i drove it around for about 45 min. to allow it to shift to fourth then stop and start over again. But I did notice I get the really long shift delay after I reflashed my truck with my SCT programer. It dont matter if I shift to Drive or Reverse it pauses then shifts. But when I am back to stock flash it does pause but not as long and it is noticeably shorter.

Sounds like you could have a solenoid hanging up. How long since the last flush.

And all the detergents and additives are probably long worn out. Tranny needs flushed every 30,000 miles. You have done 2 no-no's. No filter change and over extended your fluid. I would get it flushed ASAP and then change that ext. filter again afterwards. Just my opinion. Good luck. You have to start somewhere and getting rid of that 90,000 mile fluid has to be your 1st step.

it has been flused every 30K, and sense it has been about 15K sense the flush I cant see how the additives have worn away. The only thing I have never changed was the external filter. Just due to tha bull **** line tha dealer trys to sell you and say that tha flush will clean it.
