Jeep revving and giving ' whip lash'
Anyone know why my 98 5.9 is revving and yanking back and fourth when giving it gas? I think it might be the tranny. Also don't know if this has anything to do with the same problem but I gotta wiggle my reverse so the lights reverse lights come on.

Its hard to tell by the description but sounds like a failure in the trans could be a possibility.

We need a better description of your problems.
Does it drive fine under low/mid/high acceleration?
Rev lights are probably a pin switch or corroded connection.
When was the last time you changed/checked your spark plugs?
How is the trans fluid? Full/low/burnt/brownish/red/perfect?
When was the last full/complete tuneup?

With the yanking back and forth I'd be leaning towards an engine mis....sparkplugs/wires/ect!
A trans "should" just slip unless it's an engagement/fluid issue.
I'd also check on your crank shaft position sensor if it dies and comes back to life causing the jerking problem.

Hey Chrissrt10, what was the outcomer with this? You get a chance to check out what Escape mentioned? I would agree with Escape, I would lean toward ignition related

A little late but thanks escape for taking the time and info. I havnt had a chance to take my 5niner to the mechanic yet but will tell him what you said to check out. 1ABrian, I plan on taking her to the mechanic some point next week. I am leaning to the tranmissiob though. It has 117,000 miles on it so might be time to buy a new tranny.
