5.9l. When shifted into reverse, why is it backfiring and cutting off?

SOURCE: 1998 dodge 1500 wont shift

first of all standard or auto i am guessing its standed standard under drivers side hood near master cylinder there is a small clutch reservoir if there isnt enough fluid it wont extend the throw out bearing far enough for a shift because the clutch pedal is hitting the floor not enough fluid to extend the slave cylinder to drive the fork second faulty slave cylinder or throw out bearing as far as the light blown dash bulb or somone snipped the wire or took the bulb out

There are many things to consider with an automatic. Check that you have installed the kick down cable and spring correctly. If the kickdown is stuck or the spring is holding it in the wrong direction this will cause your problem. Insure your 8 pin plug is seated properly into into the sillinoid connector. Also check and see if any transmission codes have been set. Hope this helps.
