C6 Tranny filter change
89 F250 460/C6 auto, 4x4, EFI, reg cab, long bed
Any hints/tricks/lesssons learned before I start my transmission filter project tomorrow?
I decided against a new pan with a plug since this is just a farm truck.

just remove all the bolts except for the front next to the bellhousing, loosen these and tip the pan twords the rear. You should be able to catch all the fluid. Some auto parts stores sell a plug kit that you can install in your factory pan. but draining isnt much different than just removing a cooling line and starting it up. I like to change the filter once in awhile.

Thanks.
I'm changing it because the PO didn't have any maintenance logs (that annoys me) so who knows if/when it was ever done.
I'm doing the rear diff oil tomorrow too. I'm just going with standard 75-90 weight since it's just a farm truck.
Any hints on changing this oil out?

If you find a plastic plug laying in the pan of the transmission, you will know that it hasnt been changed since new. for the rear end, I would drive it around a bit just to warm it up and then do about the same as I told you with the tranny pan. You will probably need a hand pump to fill the diffy though. It just makes it easier. Just cheap 80w90 will be fine, if it has a limited sliip you may want to add some friction modifier for the clutches, but if it has any miles on it and its just a farm truck I wouldnt worry about it because they are probably warn out.
