Hello,I'm new to this forum & have a unique problem...my C4 will shift fine under part throttle BUT under WOT it will lock the tires as if it was thrown into Park.
Trans was rebuilt, converter is a GER I installed a BNM
transpak & shifter(BNM) is adjusted fine.
I have a spare VB but it's from a pan fil trans w/a diffrent
bolt pattern on ther converter.
Any help would be greatly appreciated!!

Check your band adjustments
Rear or low-reverse band 3 turns out.
Front of intermediate band 1 1/2 turns out.
If problem still occurs try lossening rear band a few more turns.
You may have valve body internal leakage, have seen it a few times.
