Slight jerk when auto tranny shifts

Is it normal? I've only put 200 mi on it since I've had it, trans oil looks good, doesn't smell burnt, gauge hasn't come anywhere near to peak. Wifey says it's worrisome, but I tell her, "it's a TRUCK, not a passenger sedan". Am I right, or should I be checking into it? Thanks for any ideas!

Yeah, sounds like the tuning is a bit off, you can get the quick shift without the clunk with a stock vb. Who's tunes do you run?

A ts chip with custom tunes with help alot. I tried swamps tunes and it was worse, so i went to bdp. I have heard of others who are good also. Tunes alone helped but the valve body helped that much more. Plus a vb helps the tranny live

Well I'm definitely about making this truck live forever, or close to it, so I really appreciate the advice. Much obliged!
