Question about Cars & Trucks
I noticed this question seemed to have been posted over a year ago... and started to skip over it... but then I noticed you have more than a couple of projects... (kudos).
Sounds like you got this car mostly straight...
If this is still an ACTIVE QUESTION...
a SERIOUS answer would require the MODEL...
(and a FIXER from this century... that had actually worked on transmissions with active PLASTIC parts)...
I suspect (plastics or not) the principles remain the same.
(?) Your symptoms... Well they could be clutch related...
but you would ALSO be getting one of two very distinctly
different symptoms... (slippage... or high pedal
engagement = worn clutch plate (NOT your trouble))...
Difficulty engaging (all) gears: Clutch release failure...
(most commonly caused by your clutch linkage...
(I suspect a hydraulic master, fluid line & slave cylinder
(actuator/plunger ("s" word censoring: past experience)) ...
Inspect the master... (should be clean, clear & dry).
Any moisture here will surly cause tranny issues...
But still... Your symptoms Trouble getting into 5th...
"At times"... 3&4 (still does not fit)
To me points directly at your shift selector...
(now Hyundai MODEL would allow me to KNOW
OR LEARN ... rather than speculate)...
Because your shift linkage ARE TWO CABLES

SHIFT SELECTOR: PURPOSE & Function ...
Make sure you OTHER gears
ACTUATER forks (or yokes) are in a NEUTRAL
position before allowing another gear cluster to be
engaged (avoid lock-up (multiple engagements)).
I did go out onto the Hyundai Forum and found
the fifth gear Pop-out to be a hot topic...
From all that discussion
I could only determine CYBER-WISDOM believes
transmission mounts are also critically important...
I am going to hazard a guess Like the really old
transmissions... the shift selector is at the LEVER
end rather than inside the transmission...
Good bushings & bearings will have a profound impact .
Buying or borrowing decent SHOP MANUALS
is the best way to end my speculation... or pulling
your TECHNICAL SERVICE BULLETINS (TSBs) from
the BBB Industries website (registration required)... at
BBB Industries Premium Alternators Starters Power Steering Products
Great news (if it were fact (rather than speculation))...
One TERRIBLY important TIP... Never let the weight of the TRANNY be held by the INPUTSHAFT...
>> Always use a TRANSMISSION jack...
(took me A shattered tail housing for that bit of wisdom
(fortunately DATSUN 240Z were plentiful & cheap)).
(beg, borrow, buy or rent... the transmission should be fully supported until it is completely bolted into place...!!!).
That tiny... terribly important I/O shaft (center) bearing could be damaged (very deep in the middle of your main-shafts).
450 lb Low Lift Transmission Jack
1 2 ton Transmission Jack Adapter Capacity TRANSFORM Automotive Floor Jack...
Hope this all helps...
Comment me back before you get deep into the transmission...
There are a couple of specialty tools and hot/cold tricks that
can help dis & re... assemble with minimal bleeding & damage.
(I'm just saying).

Sounds like you have lost the transmission. There are bands that clamp down to lock the transmission into the gear you want. They are controlled by a hydrolic unit located in the trans. The first thing I would do is have a shop pull the trans oil pan and see if it is full of chips of metal. If so you definately have a problem. At the same time they can look at the bands and see if one of them is broken. another cause would be that metal has gotten into the hydrolic valve body and frozen the drive band portion so it will not function. You may also get lucky and have it be an internal adjustment of the drive band. Good Luck, RAC

I would be interested in knowing if the thermostat is sticking open. Most Overdrives are prevented from engaging until the coolant temperature is over 177 degress F. Check you temp gauge...does it read Low? If so, change the t'stat, and see if that fixes your problem, or, if that does not help, get a complete transmission FLUSH, BEFORE you go out and get a rebuild. You just might save a ton of money.
