My jeep cherokee 1998 is pulling a transmission code 0P700. Does any one know what this is and what's making it show up? I have noticed that when I'm changing gears from drive to reverse it takes a while to kick in and I keep hearing a whining while it's in drive. Any help??

 

First thing to do is check the condition of the fluid in your trans:

Remove the trans dip stick and smell the fluid on the end. If it smells burnt that's not good. Touch the end of the dip stick to a white paper towl or rag and see what color the fluid is on the towl. If it's black that's not good.

Next, when the trans is cold remove the dip stick, wipe clean, reinsert dip stick then check the fluid level on the dip stick. It should be between the middle of the OK range and over the top of that range. Clean the dip stick again and set it aside. Start the engine and immediately reinsert the dip stick then check the fluid level again. It should be near the bottom of the dip stick but not lower than the ADD line. If it's too low, add a bit of fluid to bring it up to the ADD line.

Next, drive the Jeep for at least 15 miles. With the Jeep on level ground, set the parking brake. While in PARK and the engine idling, check the fluid level on the dip stick. It should be near the top of the OK range, but not over MAX.

 

(Agree with the checking of the quality of the ATF. But in all honesty, not sure why something as simple as a level-check needs to be expanded into a multi step procedure. Just check it once, after a longer drive when engine and trans are warmed up, check while idle in Neutral )

Of note: if you need to add, don't overdo it. It only takes 500ml from Add to Max with the ATF. Overfilling is as bad as running low.

 

Because, with the problems he's experiencing it is best to determine if the transmission has enough fluid in it before driving it to heat up the ATF for the actual level check.

Check the fluid level in PARK.

Edit: Read my signature.

 

We had this discussion already long ago. Park versus Neutral. Remember?
And don't worry I trust ye. Till a certain level.
I just don't see the point of making this more complicated. If he would have run dry, he would have had a lot more issues by now than only this. He can do a quick check and then drive.

 

What's a quick check?

 

you're a smart man CC, so your question suggests something else?

 

And, well in case it doesn't: black is the quick check. Blue is all the rocket science that follows a simple quick check-to-drive.

Now, with your approval of course, may I suggest we move on and actually hear from the OP how things are coming along?
Although I'd love to carry on with this, if only for future reference.
It's always a pleasure exchanging thoughts with you, CC..

Nec aspera terro. nemo mortalium omnibus horis sapit ; to give you some Latin back

 

I'm sitting here drumming my fingers waiting for his/her response.

The check I outlined is to see if the Torque Converter and/or the trans oil pump is working. If the fluid level does not drop, as described, there is a problem in this area. Of course, it is part of the cold fluid level check outlined in the Owner's Manual, page 165. wink wink

 

notch notch. I think I have that manual too,...somewhere.
(Did you like my Latin though? it's a bit rusty I must admit, but it's still there....)

 

We are up a bit early today.

 

Not sure if I understand what you mean with that, but I, for one, am turning in now. Will catch up tomorrow to see how this goes...

Nighty Night

 

The fluid is good it's up to the right hight but now the check engine lights on same with the check gages but the check gages were on before this started

 

Ok, so:

1) what do you see when you check the gauges?
2) your check engine light is on > have it read to see if any code(s) is/are stored. Check engine lights are a good point to start trouble shooting this further.

Ad 1): as far as I'm aware, this is done by looking at your gauges. But CCKen might have a different procedure for this (LOL, sorry I just had to...)

Ad 2): you can have this done at any automotive part store I've been told. Unless you have a scanner yourself. Post the codes that might have come up here.
