TC shudder

Lucentinjection · 08-16-2008, 08:14 AM

I have some torque converter shudder, happens only in OD at 40-45mph, after that it's smooth as ice...Now I know the theory of how the TC operates, but what exactly causes the shudder effect? Just a slipping tcc? Something coming apart internally? Just curious...any info would be appreciated

It's slipping and grabbing. It's applied by trans line pressure and at lower rpm theres not enough pressure to hold the power.
