View Full Version : Not shifting into OD

01-05-2009, 05:09 PM
98xj with 4spd auto. Having issues with it not seeming to shift into OverDrive on the highway. All the way up to Third it seems fine. I checked the fluid over the weekend and it seems to be little over the max line, but it must have been this way since i bought it, and this seems to be a fairly new issue. Funny thing is, this doesn't happen all the time. Only seems to be when its shifted in and out of 4x that this seems to pop up. Anyone have any ideas as to what might be the cause?

Well i just tried changing the fluid, but it still doing the samething. Seems to shift thru all the gears, but doesn't make it into OD.

Anyone have any ideas on what else to check?

Yeah Mike at Jeep Thrills figured it out. Stupid NSS does more than just stop you from starting.

O/D for a jeep ?

Isn't that just neutral on a downhill?

Thats all that mine is, and with a tailwind I got double overdrive.
