Can It Get Any More Complicated?
I understand as transmissions progress in time with the future technologies, things will change and probably become more complicated. Let’s look at what used to be a simple design, the park-pawl components found in many transmissions. We have all heard of or seen the new “park-by-wire” systems found on some of the later transmissions in today’s market. The ZF6HP and ZF8HP have their version of park-by-wire with a release cable that can physically pull the park pawl out of the park position if the vehicle were to lose power. That system was probably the first to be seen in most transmission shops.
