Hey guys, looking for a little advice here. Still reading up on this but sifting through the countless transmission threads is taking a while. Ran into an issue today where my 05 didnt want to shift at redline/under WOT. First noticed it when merging onto a highway on my way to work. Was doing about 45, stomped it to merge, and just bounced off of redline for a little before going into gear.

concerned by it, when i got to work, i stopped on a back road at a stop sign, floored it again, and it did the same thing, so i dont think it is a speed/gear dependent issue.

anyone have any ideas on what to check out?

 

Some info that i should have included here:

the car has around 14X,XXX miles on it i think. It’s getting up there
i’ve only owned it about a year and a half, but have all the service records up until when i purchased it. Looks like all of the scheduled services were done, but no major trans work was ever done.
most recently service included the transmission service which i had done at the local Acura a few months ago. They didnt notice anything out of the ordinary with it

 

Anyone??

 

 

only recommendation is pressure switches and fluid. If there's a faulty signal for the pressure switches it won't shift into the next gear to prevent damage
