Great thread and lots of useful information!!!

Have you compared or measured with the differences in the standpipe heights, the amount of fluid volume with the side drainplug removed from the case?

For the past three years with my ZLE, I have been using the side drainplug level as my mark with engine running, vehicle cycled through all gears and then idling in park while topping off. Temps are typically 100-140º when measured and with the Amsoil Signature Series ATL Blue Cap fluid. This is the ONLY fluid of the three high performance fluids that is backdated approved for DEXOS as well as CVT for extreme temperatures. The ULV and Multi-Use is not intended for racing use in an automatic.
