Ok im lost what am i supposed to do with that it is showing a parts catalog. I dont know what parts i need.

Jeepability

the autoparts store like advanced will read these for free..

98jeepcher

They read them for free to give you the trouble code such as the ones i have written in my post. They dont tell you what is wrong with the vehicle. All i need is kind of for someone to interpret these codes for me and let me know what they mean, and what i need to do i really do not want to take this thing to a shop its costly. Thanks

p0740?

is that TCC circuit?

Transmission code. I had that come on my 99 xj when my 2wd trans was going out. It was slipping pretty bad and when i would shift from park or drive to reverse it would take a few seconds to finally shift into the gear. I replaced the transmission with a 4x4 trans from there.

Also in the same respect i have had the same code with no slipping at all. In turn both times the code was present, i eventually replaced my transmission

Well thats no good but thanks for the info anyway Hope i dont have to replace the tranny.

What are your symptoms? p0700 seems to indicate a fault stored IN the tcu that must be read/retrieved with a specific piece of equipment. p0705 isn't listed, but p0740 sounds like the S3 lockup solenoid is going out, or is not functioning.

98jeepcher

Well my symptoms are intermittent overdrive. Like sometimes i will have it and sometimes not. i just replaced the s3 solenoid or atleast i think i did. i replaced a solenoid if its any help the one closest to the motor in the pan.

That appears to be S3. Have you checked the resistance? Have you swapped out the TCU?

The Wt/Bk wire in the 7 pin connector goes to S3 and to C14 on the TCU, Bk/Tn is ground from the TCU to the trans.

You have the AW4 diagnosis manual?

98jeepcher

Yes i have swapped out the tcu it worked for a little bit then quit. I do not have the diagnosis manual. Im just gonna take this thing to a tranny shop i already have an appointment set up for in the morning maybe i will get some answers there, i cant just keep throwing parts at it. The wife is starting to get mad about it ^.

PM me your email address and I'll send the AW4 diagnosis manual.

The trans shop should be able to read the codes out of the TCU, if not, the Jeep dealer should have the DRBII.

Its a Jeep thing, she wouldn't understand.

Okay so i took it to the transmission shop today just got it home. The shop says it runs like a champ and that his only guess would be nss or range something or another. Best 35 dollars i have spent in years not. Whats your alls 2 cents
