91 explorer tranny problem
I have a 91 explorer that for the past 3 months takes 3 to 4 seconds to shift into reverse. its an automatic with the stock transmision(A4LD?). even when it does finally shift into reverse it clunks really badly when its given some gas. if works even worse when backing up a hill. has anyone had this problem or know what could be causing it because it works just fine when in drive. any help would be great. -kell-

Here is something you can try which is a cheap alternative to a rebuild at this point. Most likely you have a sticking valve in the transmission valve body due to gum buildup caused by lax maintenance.
This product has been on the market for at least 30 years that I can remember and it works well in all but the most extreeme cases where actual physical damage is present.
1. Go to your local auto supply and find a quart can of K&W "Trans-X" and pour it into transmission. (you may want to remove some fluid to avoid overfilling). It is a Benzene based product that will cut the gum off the internal surfaces (and recondition rubber seals too). Benzene is some really nasty stuff though and should be used with care (read carcinogen). If it works, you should notice an improvement rather soon.
2. Drive the vehicle 100 miles or so then (read the directions carefully) take it and have the trans pan dropped and do a COMPLETE fluid & filter change.
3. If this does not do the trick, you are probably looking at a re-build sooner or later.
