93 Grand Cherokee Tranny Question

Hi Guys,
You all have been so much help.
My 93 Grand Cherokee is starting to miss/shift a bit. After 255K miles, I
guess it's allowed.
I heard somewhere that if you change the filter and fluid in a high mileage
tranny, you can stir up some gunk and cause more problems than you had. Is
this true?
Would changing the fluid and filter help with the problem?
I have no slippage, it just seems to want to shift down at different times
than it used to. It sits behind the good old 4 liter 6 by the way.
Thanks a lot guys.
Denny.

Going by the book, transmission fluid should be changed every 30,000 miles.
I believe 50-60K is more reasonable. At any rate unless your changing the
filter all it takes is a suction gun down the filler tube to get most of it.
Even dumping the pan doesn't get all the fluid, quit a bit is trapped in
the torque converter.

Hi Doug,
Next time you're thirty, smell the oil, it will smell burnt, put it
between your fingers you will be able to feel the grit like fiction.

Thanks Doug. You've never steered me wrong.
Yep, I'm doing the filter too.
Have a great one, and belated Happy Independence Day.

Good to hear from you too Bill.
