New tsb for 8speed with 5.7

There is a new tsb that just came out for transmission shift improvement that applies to the 5.7 models. Several issues are listed but the one I was happy to see was the torque converter clutch control improvements.

Noticed that too. I've been extremely happy with the way mine shifts so I feel conflicted between "if it ain't broke" and "oooo the newest thing, I want"

Re: New tsb for 8speed with 5.7

Love the way mine shifts. Not going to let the dealer touch it unless something goes wrong or a more critical update is needed.

Re: New tsb for 8speed with 5.7

Done today. Helps slow speed driving with eco mode on. That's all I was looking for, so it's all I noticed.

Several new TSBs there.
Jeep Grand Cherokee WK2 - Grand Cherokee Service Bulletins and Recalls

One for the ELSD would seem to imply that the GC will be continued for at least
another 99 years! NOTE: This bulletin applies to vehicles equipped with the ELSD (Sales Codes DSF) built before September 30, 3013

Multiple misfires on the 5.7

The aforementioned 5.7/8 speed shift quality

Bogus blind spot detections

Allow turning off the auto steering wheel and seat heating

Re: New tsb for 8speed with 5.7

I got mine back. It made an already smooth shifting transmission even smoother. Took care of the low speed issues in eco mode. It seems to be perfect now.
