Changing shift solenoids

[miller507]

Yes I tried. Everything works for a while and when this annoying sound starts coming the transmission stops working.

Well before changing the solenoids the truck was totally stuck in neutral. No matter what gear I use it didn't move.but changing solenoids worked and it ran uptil now. I dont have money to put new tranny in the truck. So looks like I have to sell the truck to a junk yard I guess. If I have no other solutions to make it work.

Whine sound? Yeah that can either be a crapped torque converter or a seal issue. Can get expensive.

I already rebuilt 2 transmission with no issues whatsoever. A340f (jan 2018) and a343f (2 months ago)

Unfortunately you are gonna have to drop the tranny.
