When cruising on the highway my Eclipse will pop out of 5th. Otherwise it
shifts smoothly and all other gears work fine. Checked the linkage and it is
properly adjusted. The car has 106,000 miles on it. What is likely to need
replacement in the transaxle? Since it shifts good could it be the shifter
fork only? How well do the thrust washers hold up in these transaxles?

TIA

Did you check the motor mounts?

Assuming its not just a mount block, it may be the following.

Fifth gear parts are held on with a big nut with a locking tab. This nut can
sometimes work loose, and start to grind its way out of the transmission end
cover.  The symptom is a partial loss of or slow synchro on the 4-5 change.
ie it may crunch on the change unless you do it slowly and carefully.

Good news is the end cover can be removed and the nut tightened and relocked
with the trans in the car. If your trans has been crunching, you''ll need to
replace the synchro ring and possibly the synchro cone as well.

It shifts fine, no crunching in any gear. It seems to stay in 5th longer if
I pop it in quickly. Does not crunch when I do this.

TIA!

Motor mounts seem fine.

I really doubt they are. They develop cracks that you can't see without
pulling them out. At 106,000, they're almost certainly poop.
Motor mounts are a VERY popular mod with the Wrong Wheel Drive crowd. You
can get a hard urethane insert that fits in the crevasses of the OEM front
and rear roll stops that helps a lot.

dude its in your transmission. Its the synchronizers, if you let it go
on it will only get worse. The other gears will start doing it. If you
have to hold down the shifter to keep it in 5th, then thats what it
is. My 98 eclipse done the same thing. I let mine go on and it also
happened in 2nd and 3rd.
