There may be something wrong with the transmission or the linkage.
Coud be linkage adjustment Or something internal
Check the transmission fluid level.
You need a new gear box (transmission)
There's probably something wrong with the reverse gear. Have it checked by a mechanic then see how much it would cost to repair it.
There can be several things that will cause your transmission not go into reverse. The most common cause is the gear in the transmission is worn.
the gear reverse don't work in the transmission,the tothers gears okey. This actually happened to me once. A piece inside the transmission had actually broken off, and there was no way to fix it other than to replace the transmission. Sorry.
If your van won't go into reverse, the transmission might be stuck. It could also be low on transmission fluid.
You blew your transmission, took out the reverse gear. You'll have to take it to a tranny shop and get it rebuilt (not cheap), or replace it yourself with one from a scrap yard. ($600 in parts, a weekend to do it)
the transmission...
what is the problem when the car will not go in drive or reverse? and the transmission fluid is still full
your transmission is about to go, usually reverse goes first
