Well that helps, but it still unlocks at every gear change. Makes sense though with 8 speeds it's 2x more likely to find the right gear and the tc will stay locked more often.
Still not an ideal setup by any means for towing 6000lbs.
Just an FYI though, the same basic trans ZF 8 speed whatever it's called is used all the way up to the Hellcat and possibly the Demon.
They have a few different model designations for the different power levels but realistically it is an over built unit for only 300hp and should not be the weak link in any equation with lower powered vehicles.
Yes it unlocks at gear changes to prevent broken input shaft. It immediately locks after gear change. You cannot tell it locks and unlocks, its so fast.
The v6 8sp is not built as stout as the v8 8sp trans. Same design, less stout. The v6 8sp is assembled by FCA with ZF design. The v8 8 sp is designed and built by ZF.
