What did you do to your NNBS GMT900 Tahoe/Yukon Today?

I need to buy some tow mirrors. Any suggestions?
The normal truck tow mirrors i think would not look decent on a Yukon.

I got my truck back today from my local tuner, who was working on eliminating a very hard downshift from 5th gear to 4th gear. He told me that he did his best, but he could not fully eliminate the hard downshift. Even though it is a newly rebuilt 6180 transmission, he believes that the root cause of the issue is something electrical, mechanical, or both inside the transmission. He gave me a referral to a local transmission specialist who would be willing to tear into the transmission to try to find the root cause of this issue. So, I will be reaching out to him in the near future.

@NickTransmissions, is there anything that comes to your mind regarding a hard downshift issue that occurs only when the transmission tries to downshift from 5th gear to 4th gear?

Was the TEHCM replaced as part of the rebuild? If so, was it replaced with a brand new, GM TEHCM?

Were there prior issues of hard 5-4 downshift before the transmission was overhauled?

Was the valve body vacuum tested?

Any codes stored in the ECM?

when I had mine rebuilt, after multiple trips back to the shop they determined it was the clutch set they used and took it apart again and used a different clutch set.
just food for thought if nothing else works...
