Have a 99 durango 5.9 4x4. Reverse does not want to engage when shifting from park. If I drive around the block and then try reverse it engages but shifts hard. Was wondering what could be causing this

SOURCE: no reverse sometimes geo metro a/t

The accelator cable is "Y" shaped. one side goes to the carb and the other to the tranmission. If you have the carb.side too tight it will give you the problem that you are having.

You will have to have the solenoid body replaced in the tranny and have the PCM reprogrammed.

SOURCE: suddenly automatic transmission would not go into reverse

seems like your gear linkage is either broken or come off, if the linkage is ok then u are looking at a replacement gearbox

SOURCE: 99 malibu horn honks shifting into D or R

wires from the horn run down the steering column and pass the area where the shift linkage is also in the column. its either a loose wire, or a chafted wire inside the column. Be VERY careful working on this if you have airbags. they must be disarmed before you work on the column.

SOURCE: cannot shift into reverse although forward gears all functional

have ur shift linkage bushings replaced....most likely thse are torn or completely broken .. this is common on these models..also on some vw's of the same years
