2007 Lexus IS 250 stuck in 3rd gear
I've changed Trans fluid, reset ECU normal till put on park it got stuck again. I've done multiple resets it shifts but when I put it on park got stuck in 3rd again. Code I found is P0171 I thought this got something to do with MAF but I replaced twice it still couldn't having problem with stuck in 3rd gear. should I replace O2 sensor, change my spark plugs? been on going for a month. really need some helps.

That code has zero to do with the transmission issue. You have a mechanical failure in the tranny most likely, but have the TCM module scanned first before doing any parts replacement. P0171 is most likely an O2 sensor issue, it is indicating lean fuel.
