Hey I have a 2000 Honda Accord stick 4cylinder - and the problem I was having is my car is stuck in reverse and won’t go into any other gear. I tried sinking the clutch , also tried jacking up the front of the car still nothing

USA spec car in USA? not told
2.3L inline 4 banger.DOHC +VVT cam. 5sp, M/T
nor real name of the box told.
Vtec is honda name for VVT, valve variable timing, and is not a transmission part at all so is off topic if we want to do 1 at a time.
a wise idea that, leaks are your problem.as all are.
your post seem clueless, here, find a real shop and get it fixed?
vtech bad causes huge engine power loss, for sure stuck in idle mode. so lets end that here.
and talk the box, what box 5 speed is it
not told at all
honda says 5speed is a manual transmission M/T
the silly cable to it is bad.
end story, endless.
2 cables clutch release snapped i gear. makes it hard to shift if you do not move car bay hand to N./ (a trick to lean 2 man job) as all tow truck drivers know for 100 years.
shift cable bad. (or levers to it)
see this first photo , one can drop off links to that #8 part and shift the box by hand, sure can and if can the box end is good .
box means transmission box in whole.,, mech jargon.
all this is pure mechanics 101 problem shifting any M/T is.
photo 2 is lever #2 id and cable set 6
one if bad, looking only finds it as is 100% pure mechanical parts.
end to end. no brains no CPU or TCM brains here, just real gears and levers and flex steel cables that love to fail not lubed regular.

if it has a cable check the adjustment , if it has a rod check the adjustment. also check fluid in slave cylinder .

Giving your some diagnostic tools for your reference :http://www.xcardiag.com/ hope it can help you.

there are many gears.
are all gears dead, forward and reverse
even at 3000 engine RPM?
is the transmission slipping
if RPM gets stuck at say 1500 to 2000 that means the brakes are frozen in ICE.

Based on Info...
Possible Sun Gear Failure, or Other Internal.
Check Fluid Level. Although it Seems Damage is Done.
Remove and Replace.

Check the fluid level. Automatic transmissions won't go into gear without enough fluid. If it's low, you've probably got a leak somewhere that you need to find.

IT sounds like your reverse gear is going out, or that you need to have filter replaced my best advise is have your transmission checked out by a transmission shop as soon as possible.

you need to have the shifting cable lubricated or replaced.

your motor mount is probaly bad and needs to be checked
