when i put truck in reverse the lights do not work but if i wiggle the shifter(auto trans) i can get them on but will go off if shifter moves. any suggestions would be great

 

ditto here... there's got to be an adjusterthingymajig somewhere

 

i agree but can not figure it out i wish someone with know would jump in because it is bugging the crap out of me

 

Had the same problem with my 98.5,replaced the nutral-safety switch on the tramsmission,solved my problem.This switch also controlls the backup lights.You can use a jumper on two of the three wires,green and brown I think.Turn the key on ,If it's the neutral-safety switch,lights should work.If you change the switch,be aware that it is below the fluid level.I lost about a quart .Also don't forget the metal washer. Good Luck!

are you talking about on the upper half of the tranny?

 

It's a three wire connection on the drivers side of the transmission,just above the pan.Don't know what you consider "upper half",but take my word for it,there will be fluid when you remove the switch from the transmission.
