Ford 4R70W

Wifes 02 F150 truck with 146 K miles has developed the typical torque converter shudder.
I've flushed the fluid (mercon V) and changed the filter. The pan had no metal on the magnet and no chunks in the bottom. I know 146K is a lot of miles but I have been advised by a repair shop owner to put in a new converter and go. He claims these transmissions are good to 300K if the pan was clean when dropped. This truck has never had a trailer on it so it has never seen any load.
Whats the consensus?
Buy a converter and install it myself or bite the bullet and get it rebuilt?
If the clutches are still good, what is the life of the electronics in these?

Just put a converter in it.If you do a lot of local and city driving it is most likely worn as with all the on -off slipping to engage puts plenty of wear on the clutches. It has cycled about a gadzillian times , probably wouldnt be such an issue if they were all highway miles.
They shouldnt have to completley remove the trans or seperate the exhaust to change it either so mention you heard that, maybe they can give you a price break.

X2 you can flush it all you want but only one true fix and you already know what that is. Now i am not a believer in snake oil fix but I had one that started to shudder and i put some DrTranny in it fix it for about 6mos and that was it so that's not a fix either. Best replace it.
(There is nothing in the "BOTTLE" going to fix it).

Temporary fixes are just that "TEMPORARY"

Did you break open the trans filter? These trans pull alot of fluid in and debris can be sucked inside and the pan looks cleaner

Thanks guys. We'll probably only keep the truck another 15-20K miles.
I didn't open the filter up. I was too worried about the yellow plastic piece I found laying loose in the pan. Duh!!! I know what it is now. LOL

If it's converter only, I'll replace it myself. I'll let the house budget buy me a trans jack.
Just didn't want to do the converter and then have to buy another one in 10K miles if the trans dies.
