I changed both O2 sensors and my check engine light was not on. Why is it shifting better and has more get up?

It seemed a little sluggish and was shifting poor for an automatic transmission. I changed both of the O2 sensors and WOW what a huge improvement. Should I also do the same with the MAF sensor??
no just clean it but if you have enough money then go ahead why not
Take your car to advance auto or autozone. They can run free code diagnostics for your car to see if it is throwing any CELs or codes. Not every code shows a Check Engine Light (CEL). A simple tune up can help, make sure the spark plugs aren’t old, and are gapped properly, the air filter is clean, and the oil is changed according to manufacturer’s suggestions. For an auto tranny you can smell the ATF (auto tranny fluid) if it smells burnt you can replace the transmission filter and replace the fluids, that could help it shift smoother also.
the MAF most likely won’t make a huge difference.
