Slight hesitation when putting into drive?

2005 Lexus GX470 Shift Lag from Park to Drive

I have the same problem with my 2005 Lexus GX 470. Took it in to my transmission guy. He had it for over a month. After replacing a burnt out pigtail and Neutral Safety Switch he found that the problem was still there. He did more diagnostics and found that the shifter is loosey goosey from age allowing the driver to shift from Park to drive too quickly and when that happens there is some kind of communication delay between the computer module and the tranny. He explained that a new shifter is stiff and does not allow the driver to just slam the truck into drive. He also demonstrated that by slowly shifting the truck through each shift P, R, N, D., waiting a few seconds between each selection solved the issue... and voila....no delay. He demonstrated this action over and over to me...with no delay. Then he shifted it quickly going from Park to Drive and the delay was there again. I trust this guy and I know he is very thorough and knowledgeable. He did not give up and pushed and pushed to solve the issue and he also writes articles for transmission magazines. I sometimes forget and shift too quickly and there is a delay but at least I know that this is not a transmission issue.

I've got this slight delay also, thought it was normal for an automatic transmission.
Someone also mentioned the clunk, getting all the prop shafts lubed solved my driveline clunk.
Stoplight creep with your foot on the brake, that's another oddity. I've just learned to press a little harder than I did with past vehicles.

Curious what the outdoor temperature was when this occurred.

Typically this is the pump in the transmission. It requires a minimum level of pressure for the friction plates to engage, more in reverse, and the condition is exacerbated in very cold weather.
