Replaced od lockup solenoid and still no od
 

As title states i replaced overdrive lockup solenoid and overdrive still only works till my jeep gets up to its running temp. It is a 98 jeep cherokee 4.0l a340 tranny. only thing i can think of is maybe my nss casing on the backside of it is all kind of cracked up. and the nut that goes on the shaft that comes out of the side of the tranny in the nss is stripped from previous owner. If that at all makes any since. please help me im about to run this thing into a wall.:brickwall:

please if this is confusing ask questions im wanting to get this fixed.

just for ****s and giggles is the kick down cable adjusted correctly

Well i can adjust it again but im pretty sure it is. Wouldnt the o/d not work at all if it were not properly adjusted?

Are you sure you dont have the AW4 tranny?

Well it could be but im just going by what the transmission parts store told me they said it was the toyota tranny.

It has the AW4 trans. Do you drive with your foot on the brake? The brake switch unlocks the torque converter.

Do you have a CEL, or have you checked to see if there are any codes present? Have you checked to VERIFY that the new S3 solenoid is within spec for resistance. You can check it with reference to ground through the female connector (7 pin) at the trans dipstick tube.

Yes i have cel codes will have them checked tomorrow after work last time i had them checked they were p0700 and p0740. and all that other stuff your talking about sorry but im lost as to what you are saying.

Your codes are related to the trans control and torque converter lockup, or lack of.

The other info I was trying to relay to you was how to test the S3 solenoid. If you don't have the skills or inclination to try and troubleshoot this yourself, you may as well just take it to the Jeep dealer and let them plug their AW4 DRB II tester in.

actually i think its the brake switch as i was driving today I kept pulling up on the brake pedal and consistently having overdrive. Do you know any fixes for this? Thanks

I haven't looked at the brake switch, but I recall that it can be adjusted or simply replaced. Take a peek and see what position its in with the pedal raised(normally open or normally closed?). You might also look and see if you have a weak return spring on the pedal. That sounds a whole lot easier and less $ than taking it to a trans shop.

lol yea i know thanks any more questions ill let you know.

Just adjusted the brake pedal switch guess i will see if that worked tomorrow

Is there anyway that the switch could have just gone bad? because it was working yesterday when i pulled up on the brake pedal and not today.
