ZF6HP19/26/32 (Gen. 1)/Ford 6R60, 6R80 Vacuum Test Guide

Vacuum testing is an efficient way to identify the root cause of transmission problems and evaluate the effectiveness of repairs. Frequent, proper vacuum testing can put money in the bank, improve turnaround time in your bays, and prevent costly comebacks.

See how easy it is to master vacuum testing and work with confidence knowing your rebuild is done right the first time.
