96 JGC trans help

[katie_parker]

hello all i need a little help with my jeep. so today the trans started to act up like it was stuck in gear and the check engine light come on so i took it to autozone and put it on a code reader. the trans oil still looked ok but the codes that come up was p0138 witch is oxygen sensor 2 the one after the cat. Before i replace it they said to try the relay under the hood but i dont know what one it is i dont have my owners manual to change it. Then it had 2 more codes that go for the trans, p0743 witch is the TCC solenoid and p0753 witch is 3-4 shift solenoid. Autozone said there is a relay in the power distribution box under the hood. i dont have the diagram to change them. I wanted to know if someone could show me what ones to change before i go rippin in to the trans to change them. im a girl but ill get down and dirty if i have to but ill try the cheeper easyer way first. anyhelp would be nice im stuck and i dont want to mess the trans up more then it is by driving it.

From what I've read online there are some relays under the hood that might work to fix this issue. You'll need a repair manual (maybe the factory service manual) to get the location of the relays.

Sorry I don't know more about it, never had this issue.
