Torque converter problems?

[Programmer]

The reason is high fluid shear in the converter in OD (higher load). The
lockup does a couple things--better overall fuel economy, and keeps the
fluid cooler. They're not weaker by any means...

CCC'd Monte SS had the same problem...replaced the TCC solenoid and changed
the tranny fluid, and all was well.  To diagnose on a 700-R4, you can
probably disconnect the TCC plug to see if the problem goes away, but don't
drive it that way for long, because they overheat and self-destruct in short
order with the lockup disconnected.

approx. 45-50 mph, and tap the brake pedal.  If the RPMs rise, the lockup is
functioning as it's supposed to.
