What can be wrong with a 1998 Ford Ranger automatic that won't go into reverse?

Answer 1

It sounds like it may be low on fluid, or maybe a dirty filter. Depending on how the vehicle is operated (Hot Roddded, Lead Foot, etc.) it could even be the clutches. The best way to find out is to pull the dipstick and check the fluid. This is while the engine is running, the vehicle is warmed up, and in park, on level ground. Pull the dipstick out, and wipe it off on white paper towels. Does it look brown? If so, this would be a danger sign letting you know that the transmission needs to be rebuilt, or replaced. If the fluid is red, almost a candy color red, then the transmission is probably ok, but the fluid is probably low. Put the stick back in, and pull it back out again. See where the fluid level is on the stick. There are two marks, and it should fall somewhere in between, if not, closer to the upper mark. If that is ok, then you need to find a trustworthy shop, or a friend that knows how to change transmission filters, because this would be your next step. If the fluid is low, have some put in to see if that fixes your problem. Then find the leak.
