Broken main shaft. Rebuild or replace.

You need a new tranny the gears broke had the same problem with a voyager around the same year to

either you have lost the reversing gear or the gear shifting solenoid will not work.

Change trans fluid and filter. Sounds like filter is starting to clog up. Trans fluid & filter should be done every 30k. More often if you do alot of heavy towing

Could be your clutch or the cable from the shifter has a plastic piece that is easily broken that wont allow proper gear placement

If it's a no crank condition, put your foot on the brake, shirt the gear selector to neutral and see if the engine will start. If it starts in neutral, you might have a faulty neutral safety switch which is located on the transmission. Very easy to change, but don't remove the steel alignment tool until you have it bolted to the transmission, Good luck, Gary

try checking your linkage on tranny, check fluid levels

If you're not experiencing a burning smell, it's most likely a clutch adjustment. The clutch appears to remain partially engaged and without adjustment, will eventually burn out. A symptom of this would be the RPM's being higher than normal when shifting.

The trans is electronic I suggest having a diagnostic run for the trans. This is only about $50 or so and is well worth it. Saves a lot of trouble shooting time.
