Not Sure What To Do With The Tranny

[Carder09]

Almost at 100k and not sure if the tranny fluid has ever been changed, I believe the man. says to change it every 60k, so before I make and sudden choices, what would be the best thing to do for now? Also, im sure none of the other fluids have been serviced either, except the religious oil changes. Appreciate any thoughts and comments.

drop the pan and change filter on trans

Machine flush trans then drop the pan and change the filter.

Drain and refill diffs and transfer case.

Replace the spark plugs.

Cool, will get to that this weekend, only thing is should I go to a service center and spend some $$$ to get a complete system flush or is there a way to do it without spendin the dough?

Most of the shops in my area charge around $100 to just do the flush on the machine and around $200 to do the flush and change the filter afterwards. Not worth the mess of trying to do it yourself in the driveway, imo.
