Unhappy 2012 Wrangler with Check engine codes.. 0734 0733

My check engine light came on Friday so I went to a local parts store to get it checked out. The following code was active:

P0733 JEEP Gear 3 Incorrect Ratio

It still under warranty, so I called the dealership. They asked me to bring it in Monday to be looked at. The light went off over the weekend. I take it there yesterday and they said that that code along with 0734 (gear 4 ratio) was stored.

They cleared the codes and said that it might have been a 'glitch' that caused the codes to trip. They said the light would have to be on for them to really tell whats going on. The sounds like complete crap to me as well.

It sounds like crap to me, but I wanted you guy's input. Has anyone heard of a check engine light tripping as a glitch?

My Jeep has 25k miles on it. It is automatic. It shifts ok as far as I can tell. The only possible issue I see is when its going into 3rd, sometimes the RPMs will jump up from around 2k to 3k for a half a second and then drop back to normal. This only seems to happen if I am driving more aggressively, ie without the ECO light on.

Maybe it is nothing, but its frustrating to be told that a almost new vehicle had a glitch and to not worry about it...

The dealership is Stateline Chrysler Dodge Jeep in Fort Mill, SC. If anyone has any word of caution about the place or can recommend a better dealership to have my warranty work completed, please let me know.

You can check this site for the error codes: P0733 Chrysler Gear Ratio Error In Third Gear OBDII Engine Light Trouble Code | Engine-Codes.com. Looks to me like they are both the same, except one is for 3rd gear and the other for 4th gear. It could have a been a glitch, as Jeeps have computers in them now, and sometimes the computers have to be reset. If it happens again, take it to another dealership, if you want, as any Jeep or Chrylser dealer can perform warranty work.

I know what the codes mean and I have looked up the possible fixes. My question was more in regards to has anyone else heard of glitches with the check engine light and does my experience seem typical of how a mechanic would handle a check engine light for a transmission problem.

It is reasonable that the dealership would want to see the check engine light on so they can record the code and document it. That way they have a direction to go in terms of diagnostics. IMHO

Ok. Thanks. I plan on driving straight to the dealership instead of making an appointment next time if it goes off.

sounds like the dealership knows the codes are/were there but don't know how or don't want to correct them. their first attempt to clear and HOPE it never comes back.

Great idea. Even if you swing by any Jeep quickly, get it documented (and grab a hard copy record) that way you can go about your business and tend to it at your convenience.

if there is a computer involved then there can be a glitch. If you have thrown only 1 code in 25000 miles I would not be too concerned unless you start throwing them often. You did not post if you have bigger tires or have done any mods. I still think however that it could very likely be a glitch.

The bolded portion of your OP is the part I would be worried about. Unless I am reading it wrong, you have some sort of transmission shift flare that occurs when shifting into 3rd. If you can reproduce this, I would bring it in to show them. Shift flare in an auto transmission is not normal.

The standard operating procedure for every Chrysler dealership I've been to is to reset the computer and hope it doesn't come back...it has always come back. I haven't had that code appear yet....probably because I have a stick, it might be the only code I DON'T get. Still love the JEEP though.

Wow, I've thought of a code like this but I never knew one existed.
An Incorrect ratio could would have to be thrown by monitering your wheel speed or shaft speed coming out of the transmition, and the engine RPM. A Few things could cause this not to agree.

1: Slipping Clutch
2: Clutch Pedal Improply adjusted, so the PCM things that the clutch is let off of, when it's not.

3: A Speed sensor going out on the transmition

This is mearly speculation and an educated guess. Goodluck,
Id bet it's a clutch.

When in gears, watch your RPM and your MPH. See if you ever notice your RPM increase with a lag on your MPH. See what MPH and RPMs match up in what gears. Also, if the clutch is slipping, it's probably worn out. This is not covered under warranty.

Edit:
Whoops,
Just saw you have an auto-matic.
Check your fluid level, (with engine running and transmition warmed up)
If that's good,
Something is probably screwed up in your tranny then. That SHOULD be covered under warranty.

Thanks for the information! The check engine light hasn't came on since they cleared it. I paid more attention to the RPMs and it's not really a spike. It jumps a little during shifting, but it doesn't seem like that much of a jump and doesn't happen often. I think maybe the light bothered me and I started to get over sensitive with the transmission and shifting.

I have another 11k miles of the bumper to bumper.. That should be enough to tell.

It will put it self into limp mode it there was a real problem. And the check engine light would flash if it was serious. Just what I think. I work at a dealership but don't fix em lol so take that with a grain of salt. Those 5 speeds are pretty reliable though. You have to remember a lot of these dealerships will only diagnose with the Chrysler computer and they aren't trained to actually diagnose and problem solve. They are trained to replace.

I thought there was a way to read your codes on the EVIC display?

Yup found this:

Most people reading want to hear the outcome! Not all of us just like to hear the sound of our keyboard strokes. LOL

Fault codes for gears 1,2,3, and 5.. They are going to open the transmission and see what's going on. They said they have a transmission guy who will be out till Tuesday who will be doing the work when he gets back. Till then I will be enjoying the Dodge Avenger rental.. :-/

Hopefully it's an oddball glitch, that way it won't be common and they should be able to fix it right. If you are lucky you will get a new transmission and tc if there are issues, and someone won't attempt to rebuild it.

Im not sure if I should start a new post or not..

The check engine light has not returned after the repairs.

The only lingering issue is when going into 3rd gear sometimes the RPMs will flair.. they will jump up about 500 to 1000 RPMs then back down to normal. This doesnt happen all the time, but it does seem to be isolated to going into 3rd gear. I have a 2012 Wrangler with automatic trans. I spoke to the dealership about it and they say that they did check everything out and see no issues after the repair and driving the jeep around for about 30 miles. They did offer to have a service tech ride with me to see what Im talking about.

My question to the forum is.. Is this something I should worry about? Am I being over sensitive? How smooth should the shifting be on a wrangler versus a sedan?
