That may be tranny shudder if it does it around 45 and 50.Aka torque converter shudder.It may be unlocking as soon as it locks.Feels just like a miss.fluid replacement may help it your lucky.

Could be ignition or tranny.
Get the misfire counters read by a tech with the right scan tool. A misfire doesn't always light the check-engine light.
Try to get it to do the "miss" or "shudder" or whatever it's doing, and without turning it off, get the tech to scan the misfire counters.
If that doesn't show any misfires, I'd suspect the tranny shudder. Get the fluid changed (completely!) and report back.

Some people change the fluid and the problem disappears,others say they had to have it rebuilt.
I've heard a shift kit both hides and avoids this problem if done soon enough.
If the OD light isn't flashing and the fluid is old change it now.
Have the pan dropped,filter changed and converter drained ,some have plugs some don't.
I would go to a reputable tranny shop and not say a word about the shudder.If they find excessive clutch material(sludge)and metal filings they will let you know or ask them what the pan looked like.
Flushing the system with a machine is a bad idea especially on an older unit with or without problems as it can stir up any crap in the pan and block passages.Plus it's always good to see whats in there.
I would double check and totally rule out a miss before allowing work on the tranny unless it becomes obvious.
good luck
