I only paid what it costs for a new filter, fluid, and a pump with a very small hose...that is small enough to fit in the fill bolt of the tranny.

You have to remove drain bolt and it is reccomended you use a new one upon putting everything back together, but your discretion on this. After drained, remove the tranny pan. To do this you will need a jack to hold up T-case and Tranny, as you have to remove the cross member to get to a few of the tranny pan bolts. Then remove the few bolts holding the filter on. Install new filter, pan, and cross member in reverse order of removal.

Then remove the convertor sump pan..this will be forward of the tranny pan. be careful to not damage the wires or components when doing this. Poor Tranny fluid in this pan then hold it up in place and bolt it in. This drains about a quart more of fluid than just removing the Tranny bolt. Next remove Tranny fill bolt and pump it full of Tranny fluid. Next start VX and shift slowly down thru the gears and back up, check Tranny fluid level and fill (while VX is running) and then shift thru the gears again and fill one more time. Not worth $150 to pay someone to do, unless you do not get a pump with a small enough hose to fit into the fill hole of the Tranny.
