727 Shudder in Reverse, then rattle on 1-2 shift

Okay, that makes sense (the low/reverse not applied in first gear when in Drive). I will adjust the kickdown and then post up results. Just for grins and giggles, before I adjust the kickdown, I will drive it in manual low and then shift to second to see if the noise is still there.

Unfortunately, I am out of town for the next week, so I won't be able to crawl under there for a couple weeks. At least this truck is not my daily driver. Yes, I will check and determine the apply lever ratio. I am sure I have it written down. I will also determine what type of kickdown band I have as well as the band strut. Thank you very much for your help.

Anytime. I hope the band adjustment t helps. But more than anything it should point us in the right direction. The list of possibilities for this issue are very long. So gotta knock things out one at a time.
