The reverse went out in the transmission then later the rest of the gears went out

Shift the clutch into first and second gear several times before attempting to shift into reverse if you have a manual transmission. Sometimes the clutch jams between the torque converter. Some minimal shifting between gears usually loosens the clutch, which enables you to put the car in reverse again.

An automatic transmission consists of a series of bands (gears) which is each gear within the transmission. You state that truck will move in reverse, but not in drive. The loud pop you heard was the forward gear band breaking. From this point you have two options...either have the transmission rebuilt or replaced.

MORE INFORMATION:
Does it also grind in reverse while running?
Does it go in gear easily if the engine is not running?

NOTE:
Both gears are unsynchronized.

INFO:
The transmission needs to come to rest before it can go in gear.

FACT:
Your clutch is not disengaging

RECOMENDATION:
You have a failure in your Hydraulic clutch, Check the clutch master-cylinder and or find the leak, The higher probability is that the slave cylinder has failed.



Hope this tip helps you solve helps problem.
this problums needs to be solved sooner than later.

Just check the transmission oil levels first, if they are low this will stop it from engaging into gear.

have it scanned, could be as simple as a mlp sensor...manual lever position. or what ya dread, a overhaul

First gear and reverse gear run off the same band inside the transmission. the rest of the gears will start having problems soon.

check power to the reverse shift solinoid

It sounds pretty right on..
I mean - its unlikely that reverse would be torn up - unless some one grinded the heck out of it.. Or had trouble getting it in & slammed it in maybe breaking a few teath..

i had a nissan pickup that would whine in all gears except 4th...it started out with 1st then reverse then went to the rest...solution was new transmission...or rebuild cause the syncronizers or the gears them selves are being chewed up...the new transmission was cheaper then a rebuild. or take it to somewhere that will do free diag on the transmission.
