HELP!! Strange sound!

[The Jc2203]

So I have a 1998 t4r 3.4 2wd Auto, and when I get up to about speed and start slowing down in between 15-11 mph i hear this metal on metal sounds like it is clanging back and forth also when I shift out of park to drive I hear another metal hitting metal sound, also the previous owner pulled the truck behind a motor home and had a transmission free on the drive line and i have removed the disengage clutch and have made sure that the drive shaft cover stays in place, Im planning on making an appointment to a local mechanic unless you guys have any ideas thanks in advance!

That def sounds like you have transmission woes, had that happen on an 85 dodge d50 ended up needing new trans
