I just had the TSB flash done (finally a dealer that could do it!). No improvement here. The tranny is still clunky.

I've driven the BMW 528i and the Chrysler 300 with the ZF 8 speed. Those cars were so smooth. I wish mine was

From that article...

"Any criticisms of the 8HP have to do with the individual tunings a carmaker applies rather than with the unit itself."

I'm even more convinced it's purely a software issue now...

The service advisor at this dealership is kind of clueless so I gave him the TSB on this. Hopefully they just apply it and can get it back sometime today.

Got mine back today after they blew out the radio, kept it for 4 days and allegedly performed the TSB. There is zero difference in the transmissions response what-so-ever. This car is going to be a nightmare. Thank god I can dump it back on the dealer in 3 years.

Anyone noticing a rough downshift from 5->4 after the update? I feel like this update was 75%, a good start but they have a ways to go yet.

Re: FLASH: TRANSMISSION SHIFT ENHANCEMENTS (vehicles with 3.6L engine)

From what I've been reading on this thread, I think I'll hold off on any reprogramming. Looks like they need to fine tune this a little more before it's ready for prime time. Went through this with my '08 Enclave. Took GM a couple of tries to get it right.

I have that now before the update. They are coming to pick me up and I should be able to tell shortly how it reacts.

Re: FLASH: TRANSMISSION SHIFT ENHANCEMENTS (vehicles with 3.6L engine)

Update on Flash: The update made a difference on mine (so far). The clunking is almost un-noticable downshifting from 5-4. It still seems to get to 4th by 20mph. When I would step on it (say on the highway in 8th), it would clunk a little to 7th, no more of that. Going from 1-2-3 and 3-2-1 is less lugging as well. Overall, I would say it made it better but maybe not as great as some would hope.

They performed TCM and PCM (TSB 18-034-13 and TSB 21-007-13)
