CEL with code P0700

[hyde]

It came up today on the way to work.
700 ---> The automatic transmission computer or Aisin computer has a problem
Based on some online searches, the code seems to be a general master code, and that there could be sub-codes that are not displayed on the jeep, but can be determined by a digital reader, it could be something minor or major, not sure.

Seems to be common with Dodge Dakotas: http://www.dodgedakotas.com/boards/gen/3045.html

I did notice that when I was pulling out of our driveway just few minutes ago, i felt like a sitting duck in the intersection. I hit the gas and the jeep would take almost a second or so to get moving, although I was rolling at the time..

My code list for P0700 states Transmission Control Malfunction.
Haynes Manual: Transmission Control system (MIL request)
Phone a dealer and see if they got info/feeling on that code.
Check your HOT fluid level In Neutral, level surface is it ok?
Any clunk/ click or hard surge when u stepped on gas? hopefully not a broken accumulator/spring/valve.
Going to have to pull the pan... and have a look if it persists. Mine has done the hesitation thing before too when cold. It takes 30 minutes of driving to really get things warmed up.
A shift kit is inexpensive and may help a lot if you got the 42RLE.
You were in forward when it happened /driveway right?
Try letting the jeep warm up a few minutes in Neutral, with hand brake on, and try it again..does the light remain on now?

 

[hyde]

Yes, in forward. Went to autozone, they told me the code is 0700.. and nothing much else.
Called the dealer, "the service adviser is not available" so i have to call later. I will drive home this evening, I am planning to disconnect the battery overnight and check it again in the morning, to see if it comes back.

 

[LibertyTC]

As long as you got all the gears, you are ok 4 now. Definitely check the fluid level in N, before you tun it off tonight. It should be on the full line- it might be a bit low?
Might as well check your battery voltage after it sits overnight with ground off too.

The P0700 code is just the TCM requesting the MIL to be turned on with no specific problem.You will need a very good scanner and test equipment to diag that code.A very good trans shop or the dealership are your only options and neither will be cheap.

Dealer had the jeep for two weeks now. First they said it would take them 3-4 days to get it in since I am a "walk-in" then 3-4 days later they probably ran a simple reader and it spat 0700 and they put it aside waiting for real transmission technician, meanwhile they said they were waiting to see if it would be covered under warranty. Today they said they got a transmission shop to check it out because they could not determine what was wrong with it. This is supposed to be a 5-Star dealer, one would think they should have a transmission mechanics in there, but it turns out they don't. Final word is, it will go in tomorrow and they will let me know by tomorrow afternoon. So 2 weeks wait. I will be writing to Chrysler about this.

I had a P0700 once... was just a hickup... never showed up again...

 

[hyde]

This doesn't feel like a hickup. Resetted, it came back. I have sluggish acceleration which could be due to delayed transmission action or slipping somewhere.

Ugh, sorry to hear it Hyedipin. All things 'transmission' give me the willies. Let us know how it goes.

Sounds like the soliniod pack starting to go,about $700 after labor.

 

[hyde]

at 69500, hopefully covered under warranty.
Is this solenoid something to do with purge solenoid, or are there more than one selonoids?

Your trans is shifted by a soliniod pack that is located internally in the trans,no relation to the EVAP system at all.

That's actually not bad. I thought anything on the repair bill with the word "transmission" in it started at around $1,500.

Most times it does with these electronic auto's,old school auto's you can get a whole rebuilt one for about half of that before the core charge.

You know, the same thing might happen some thousands miles away as well.... A quite similar problem is what moved me into searching info about the XJ ( see my thread about ATF ...).
My neighbour is having P700, P702 (speed sensor) and and P0753 ( solenoid A electrical ). All codes I got by using an Innova 3140 scanner and a more interesting AutoEnginuity laptop based one. As the poor guy is continuosly changing sensors and solenoids, I humbly suggested that, either he is 'cursed' ( You know voodoo is popular here ) or better, should ( as a general rule and when feasible ) check the wiring ( I know, solenoids are internal, so tjkj2002 may well be right, as usual!)

But of course, being 'diyman', mine is just a guess....

 

[ttarmoom]

Hyde, did the problem ever get solved? If so, what was the issue and how was it resolved? Thanks!

Bump. I am having the same issue. Has anybody else had this issue and got it resolved?

Any suggestions would be appreciated.

This was my first result on a Google search. Wish cause and effect would have been posted.

 

[HoosierJeeper]

What other codes are you getting?

I just had to get my trans rebuilt as a result of PO700 with PO740 and PO1776

I had codes read at Autozone. That was all that was there.

Can I buy what I need to get all the codes?

Next step is to take it to a dealership and have codes read.

You'll need a special scanner to read the codes...it would be worth to go to a transmission shop and pay the $100 or so to get a complete diagnosis. They'll read CVI (clutch value indexes) which will tell you how much life is left in the major components.

My dealer was completely incompetent. Took them 4 days for them to say they had no idea. The shop had it diagnosed in a half day and was way more thorough than the dealer.
