Family member has subject truck and xmission fluid has never been changed,
now at 97K.
Before I offer to help with new fluid I need to have the following
answered,please:
Does it take Dexron?
Are gaskets available for the sump container? Does it use transmission
fluid filers?
Thank you,
Seamus J.Wilson

Yes, Dexron-III. There is no real filter, just a fine mesh screen.
Probably no need to pull the sump pan. About 14 quarts gives a complete
flush. 4 quarts for a sump drain & refill. With that mileage, I'd
clean the transmission with Auto-Rx for their
slow (1000 mile) safe cleaning, then the complete flush through the
cooling lines. It is smart to install an inline filter in the cooling
line after the flush. Magnefine or SPX Filtran makes the filters, about
$25. Don't forget to flush and renew the power steering fluid--ATF, and
the brake fluid. They all deteriorate with heat and time.

Thank you for the reply.
I pose another question: how do you drain the transmission fluid without
removing the pan?

Unscrew the drain plug. This drains about 1/3 of the fluid. There is
no easy way to drain all the fluid.
