2004 F150, 5.4 automatic, 160K miles
Just read about my problem and repair of the overdrive retaining snap ring,
my overdrive does not work. But I cannot find a schematic or step by step guide to do this. Local shops want to replace entire transmission. Article I read said can be done w/o removing trans.
Anyone here can help with this or recommend something else. I'm capable
just clueless on auto tranny repair.

Thanks
