hang against the bearing retainer and when
the rpms get high enough the presure plate
is popping the release bearing back.
unless of course.....
you have an automatic blasser....
you didn't volunteer that info .......
I get a Thump in transmission when acceleration from a stop at about 25
mph. when acceleration. otherwise it runs ok. have been told that it is
a major problem and the transmission should be replaced??
any advice welcome as to probable cause.
