t-45 sticks in 4th

one night out of the blue I was driving home from work and when I went to shift out of 4th it needed a little more effort to get it out of gear, I had it back in fourth after I made my turn and it didn't do it again that night.

it does it randomly every once and a while, and it just started out of the blue, I don't take the car over 3.5k rpm or dump the clutch or anything. It also isn't grinding gears at all, just the notchyness that's always been there. It doesn't do it in any other gear, and its not hard to get out just needs more of a nudge than the other gears.

I'm also wondering if the squeak that I have when the clutch is engaged is somehow linked? Its a high pitched squeak that started about a month after the clutch was replaced and it happens in all gears including neutral weather its moving or not and it goes away when the clutch is disengaged.

I've owned this car since 6-25-10

I did the tob along with the clutch, before then it was only squeaking when the clutch was disengaged

Pedal to the floor and it doesn't make a noise, release the pedal and it starts squeaking.

Someone told it the main input bearing, and I really don't feel like tearing into another transmission.

this is a lexus but this is EXACTALLY what mine does push it a tiny bit and it goes away
