transmission shakes when downshifting??

i have a 96 F250 w/ the 5speed and just rolled 225k the problem i'm having is when i go to downshift coming down a hill or coming to a stop the tranny starts to shake and will shake the entire truck if i dont drop it into neutral and just use the brakes. it's especially bad in 2nd gear and pretty bad in 1st and 3rd. i didn't notice much anything in 4th and 5th when i came down the pass last night hope that's enough info to figure out somethin let me know if i can add anything else. thanks in advance you guys are always awesome

Do you still have the factory Dual Mass FlyWheel (DMFW)? If you do, you may want to remove the inspection cover and check it. Make sure all the springs and retainers are still there and check how much the two masses can couter-rotate against each other (measured at the rim, it shouldn't be more than 5/8"). I guess I'd also look at the driveline U-joints too. Cheers!

It does have the factory dual mass flywheel still. Thinking about switching to a single for sure. Just torn on going Luk, southbend, or valair. Any suggestions on which ones best? and I'll definitely take a peek at those joints this afternoon.thanks

I had a SouthBend Con-O on my 94 and liked it. I wasn't sold on the Kevlar pilot bushing though. Cheers!
