Converter locks up

[JasonB]

My converter in my 85 Ttype locks up to early, like 30 mph or as soon as it hits drive. I put a switch on it to keep it from locking up when I dont need it to, But if I get on the highway and do 65-70mph I lock it up but once I do that even if I turn it off it will continue to lock up until I put the car in park and shut it off. Once i start the car again it is fine. Trans and coverter are new.
Thanks
Jason

Sounds like the classic sticking TCC solenoid. Not uncommon on these aging TRs at all. Just install a new solenoid and that should cure it.

Thanks,
I'll have to check that solenoid.
